According to the Vertical Angles Theorem, two crossing lines' opposing (vertical) angles must be equivalent.

Each pair of opposite angles formed by two crossing lines are referred to as a vertical angle.

Proving ∠1 ≅∠3 and ∠2 ≅ ∠4:

(1)   m∠1 + m∠2 = 180°    // straight line measures 180°

(2)   m∠3 + m∠2 = 180°    // straight line measures 180

(3)   m∠1 + m∠2 = m∠3 + m∠2          // transitive property of equality, as both left-hand sides of the equation sum up to the same value (180° )

(4)   m∠1 = m∠3                           // subtraction property of equality (subtracted m∠2 from both sides)

(5)   ∠1 ≅ ∠3                            // definition of congruent angles

Similarly, for ∠2 ≅∠4:

(1)   m∠3 + m∠2 = 180°                      // straight line measures 180°

(2)   m∠3 + m∠4 = 180°                      // straight line measures 180°

(3)   m∠3 + m∠2 = m∠3 + m∠4            // transitive property of equality, as both left hand sides of the equation sum up to the same value (180°)

(4)   m∠2 = m∠4                              // subtraction property of equality (subtracted m∠3 from both sides)

(5)   ∠2 ≅ ∠4                               // definition of congruent angle

volcanism is the result of forces that transports heated material to or toward the surface of the earth.

The process of molten rock erupting to the surface of the Earth is known as volcanism. In addition to being connected to tectonic movements and a component of the rock cycle, volcanism is a result of the heat generated by the planet's interior. When hot lava touches the Earth's surface, volcanic eruptions take place. The tectonic plates are displacing one another along constructive plate boundaries. To provide a fresh passageway for hot magma rising to the surface, the Earth's crust is split apart. These conditions can occasionally produce volcanoes; Iceland is one example.

Weathering, erosion, transportation, deposition, and lithification are the five steps in the formation of a clastic sedimentary rock from its pre-existing parent rock.

Weathering is the first step in the process of clastic sedimentary rock formation. Weathering is the breakdown of the parent rock into smaller pieces due to the action of wind, water, and temperature changes.

Erosion is the second step in the process of clastic sedimentary rock formation. Erosion is the process by which the smaller pieces of the parent rock are removed from the surface and transported to other locations due to the action of wind, water, and ice.

Transportation is the third step in the process of clastic sedimentary rock formation. Transportation involves the movement of the smaller pieces of the parent rock from one location to another.

Deposition is the fourth step in the process of clastic sedimentary rock formation. Deposition is the process of the smaller pieces of the parent rock being deposited in a new location.

Lithification is the fifth and final step in the process of clastic sedimentary rock formation. Lithification is the process of the smaller pieces of the parent rock being compacted and cemented together to form a solid rock.

Cool air constricts and sinks, while warm air expands and rises. The right response in this case is option A.

The molecules are separating as they heat up and travel more quickly. As a result, air expands when heated and shrinks when it is cooled, like most other things. The air is less dense than the surrounding material because there is more space between the molecules, which causes the heated air to float higher.

When the air gets cooler, the reverse takes place. The air bubbles shrink, becoming denser and sinking because their weight now occupies a smaller volume. This may occur if air particles travel away from the heat source; they may have climbed very high, relocated to a location over a cold lake, or shifted to an area under partial shade.

Significant environmental problems caused by the agricultural practice of tilling include soil compaction from compost addition, intercropping by conventional farmers, eutrophication from excessive fertilizer usage, and ozone depletion from fossil fuel consumption. This statement is true.

Tillage causes soil compaction, which is a serious environmental problem. Tilling is the process of turning the soil over before planting a crop. Soil erosion is the main environmental problem caused by tilling.

Tilling systems have an effect on soil's physical, chemical, and hydraulic qualities as well as crop yield. Tilling alters the top soil layer, alters how soil porosity is preserved, and decreases soil organic matter.

When soil particles are packed tightly together or lumped together, compaction occurs. This results in the soil having fewer pores, which reduces water penetration and soil aeration. Soil compaction is a significant environmental issue brought on by tillage.

A turbine running on Genevieve hill might theoretically produce roughly 30% more power than a turbine operating on Ashley hill if the wind speed is on average 12 mph on Genevieve hill and 11 mph on Ashley hill.

For wind turbines to start spinning and producing power, there must be a minimum wind speed (often 12–14 km/h). Strong winds are required for full-capacity generation (50–60 km/h).

Even a light breeze causes the blades to rotate, releasing kinetic energy. This causes the shaft in the nacelle to revolve as well, and a generator inside the nacelle transforms the kinetic energy of the rotating blades into electrical energy.

A typical onshore wind turbine may generate between 2 and 3 megawatts (MW), or more than 6 million kilowatt hours (Kwh), of power annually. That will be adequate to satisfy the electrical needs of around 1,500 typical families.

Answer: Terrace Farming is the best method to prevent soil erosion in an agricultural area. Thus, it is Option (D).

Explanation: Terrace farming refers to farming in which steeply sloped surface-like hills (higher altitudes) are cut into flat layers, resembling a series of steps on which various crops are grown. Rainfall takes soil with it, leading to erosion. Terrace farming mitigates the effects of erosion by slowing water runoff and trapping it in individual layers along the incline.

Slash-and-burn agriculture refers to the clearing of wild or forested land and the burning of any remaining vegetation. This deforestation causes the soil to erode since there is no vegetation left to hold it.

Integrated Pest Management (IPM) is a sustainable, science-based, decision-making process that combines biological, cultural, physical, and chemical tools to identify, manage and reduce risk from pests and pest management tools and strategies in a way that minimizes overall economic, health, and environmental risks.

Monocropping is the agricultural practice of growing a single crop year after year on the same land, in the absence of rotation through other crops, or growing multiple crops on the same land, which is known as polyculture.

The grid system used to locate points on the surface of the earth is a system of lines that divide the earth’s surface into a series of squares. It is also known as a geographic coordinate system or a geographic referencing system.

The grid system is used to map out an area and make it easier to locate points of interest on the earth’s surface. The key reference points in the grid system are as follows:

1. The Equator: The Equator is an imaginary line that runs around the middle of the earth and separates it into the Northern and Southern Hemispheres. It is the reference from which all other lines of latitude and longitude are measured.

2. The Prime Meridian: The Prime Meridian is the line that divides the earth into the Eastern and Western Hemispheres. It is the reference from which all other lines of longitude are measured.

3. The Lines of Latitude and Longitude: The lines of latitude and longitude are imaginary lines that run around the earth in a grid-like pattern. These lines intersect each other at right angles and are used to locate points on the earth’s surface.

4. The International Date Line: The International Date Line is an imaginary line located at 180 degrees longitude, which marks the transition from one day to the next. It is used to keep track of dates when crossing the International Date Line.

5. The Origin: The origin of the grid system is the point of intersection between the Equator and the Prime Meridian, which is located in the Gulf of Guinea off the coast of West Africa. This point is used to measure all other points on the earth’s surface.

These five points are the key reference points in the grid system used to locate points on the earth’s surface.

Much of the Ethiopian landmass is part of the East African Rift Plateau. Ethiopia has a general elevation ranging from 1,500 to 3,000 meters above sea level. Interspersed on the landscape are higher mountain ranges and cratered cones, the highest of which, at 4,620 meters, is

. The northernmost part of the plateau is Ethiopia's historical core and is the location of the ancient kingdom of Aksum. The national capital of Addis Ababa ("New Flower") is located in the center of the country on the edge of the central plateau.

Millennia of erosion have produced steep valleys, in places 1,600 meters deep and several kilometers wide. In these valleys flow rapid streams unsuitable for navigation but possessing potential as sources of hydroelectric power and water for irrigation.

The highlands that comprise much of the country are often referred to as the Ethiopian Plateau and are usually thought of as divided into northern and southern parts. In a strict geographical sense, however, they are bisected by the Great Rift Valley into the northwestern highlands and the southeastern highlands, each with associated lowlands. The northwestern highlands are considerably more extensive and rugged and are divided into northern and southern sections by the valley of the Abay (Blue Nile).

North of Addis Ababa, the surface of the plateau is interspersed with towering mountains and deep chasms that create a variety of physiography, climate, and indigenous vegetation. The plateau also contains mountain ranges such as the Chercher and Aranna. Given the rugged nature of these mountains and the surrounding tableland, foreigners receive a false impression of the country's topography when Ethiopians refer to the landform as a plateau. Few of these peaks' surfaces are flat except for a scattering of level-topped mountains known to Ethiopians as ambas.

The answer that is incorrectly matched is C. Aggradation is the process by which sediment is deposited on the bed or banks of a stream, leading to an increase in the elevation of the stream bed. Therefore, aggradation is not an area of erosion, but rather an area of sediment accumulation.

A cut bank is an outer portion of a stream meander, which is an area of substantial erosion. The erosive forces of the stream cause the bank to become steep and undercut, resulting in a bluff or cut bank.

A point bar is an area of deposition, where the stream slows down and deposits sediment. Point bars are usually found on the inside of meanders, opposite of the cut bank. Point bars are often characterized by having a gentle slope and sediment accumulations.

A braided stream is a stream with a maze of interconnected channels. These channels are formed as sediment is deposited in the stream and the stream splits into multiple channels as it flows. Braided streams are often found in areas with high sediment loads, where the sediment is deposited faster than it can be moved downstream.
