Which of the following is true about the age of rock layers and the age of the Earth? A. The top layer in a sequence of rock layers is older than the Earth. B. All rock layers are older than the Earth. C. The Earth is older than any rock layer. D. The bottom layer in a sequence of rock layers is older than the Earth.
Answer:
The Earth is older than any rock layer.
Explanation:
The rock layers on our planet are numerous, and each of them represents a particular geological period. They occupy anywhere between 25 and 70 km in-depth, or rather the uppermost layer of our planet. And while some of these rock layers are over a billion years of age, they are not older than Earth. Earth has initially formed from a nebula, space dust, which over time consolidated, and it took at least a couple of billions of years for the first rocks to occur.
The rocks only started to form when the conditions were right on the surface, or basically when Earth cooled enough so that the magma can cool down and solidify. Since the formation of the first rocks, the process has not stopped, and there is the constant formation of new ones, pilling on top of the older layers. It is not just that new rocks are forming though, but older rocks are getting subducted and end up in the mantle where they melt and get recycled.

What are some economic challenges that Cuba is facing? Be sure to discuss at least three examples.
Answer:
Cuba faces different problems such as deforestation, water pollution, the loss of biodiversity, and air pollution.
Explanation:
Deforestation, water pollution, biodiversity loss, and air pollution are just a few of the issues that Cuba is dealing with.
What is Deforestation?Deforestation is the human-caused clearing or thinning of forests. One of the main problems with global land use is deforestation. The majority of croplands today receive enough rain and heat to support many types of woods in the past.
The area of forest cleared for human use, including the removal of trees for wood products, croplands, and grazing grounds, is the basis for estimates of deforestation traditionally.
Clear-cutting is a technique when all the trees are taken down, completely destroying the forest. However, in rare circumstances, even incomplete logging and unintentional fires thin out the trees sufficiently to significantly alter the forest's structure.
There is a long history of converting forests into land that is used for other purposes. The majority of the planet's 49 million square km of farmland is deforested land.

Which of the following is true of the Antarctic Treaty System?
A. It allows limited weapons testing of the continent.
B. It limits restrictions of environmental controls.
C. It encourages scientific research.
D. Members came from the Antarctic Agreement.
Answer:
The Antarctic Treaty System encourages scientific research.
Explanation:
The Antarctic Treaty has been put in place in order to prevent escalation of the situation during the past century, but also to prohibit any violence and military interventions in the continent. Numerous countries rushed to take their piece of Antarctica with the goal of taking as much as possible for further exploitation. This led to a lot of tensions, so luckily all sides set at a table and solved the problems in a diplomatic manner.
There are a lot of articles in the treaty, but one of the most important ones is the one that focuses on science. This treaty supports scientific research and encourages the countries to do so. Not just that, but it encourages collaboration between the countries in their scientific teams in order for them to get closer and to work for mutual and global interest.

NEYT QUESTION
ANSWER:
b. Similar fossils of plants and animals are found on widely separated continents.
c. Remains of tropical plants found in Antarctica.
d. Matching jig-saw puzzle coastlines, particularly with the west coast of Africa and east coast of South America.
EXPLANATION:
Continental drift is the earliest ways geologists believed continents moved gradually. The continental drift theory is connected to the scientist Alfred Wegener. He was certain that all continents of the Earth were once fragment of a mammoth, single land form known as 'Pangaea'. Wegener a trained astronomer, used botany, geology, and biology to define Pangaea and the continental drift.
For instance, fossils of the primeval reptile Mesosaurus, a freshwater reptile,were only found in South America and Southern Africa and Mesosaurus being only one meter long would not have swam the Atlantic Ocean. The existence of Mesosaurus suggested a single habitat with several rivers and lakes. Wegener studied fossils of plants from the glacial Arctic Svalbard Archipelago, Norway.
These plant fossils were not the sturdy specimens accustomed to subsist in the Arctic climate. These fossils were that of the tropical plants, which adapts to a more humid, much warmer environ. The existence of these fossils submits Svalbard once had a tropical climate.Lastly, Wegener studied the stratigraphy of mountain ranges and different rock.
Africa's West-Coast and South America's East-Coast fit together like jigsaw puzzle pieces, and Wegener learnt their rock layers fit very clearly. Wegener uncovered that the Eastern United States' Appalachian Mountains, for example, were geologically connected to Scotland's Caledonian Mountains.
The correct options are A) Remains of tropical plants have been found in Antarctica, C) Mountain ranges in North America match up with those along the European coastline. and D) Similar fossils of plants and animals are found on widely separated continents.

although china has the largest population in the world, what explains the country's declining NIR?
Answer:
China has declining NIR because of the measures set to prevent the families from having more children.
Explanation:
China is the country with the biggest population in the world, having over 1.3 billion people. For comparison, this is aproximately the same as all of Europe and all of North America combined. It is not just nowadays that China is the most populous country, but it has been for several thousands of years now.
Things seem to gradually change though, and this can be easily noticed by China's declining NIR. This has actually been done on purpose by the Chinese government, almost half a century ago. Seeing that if the population continues to grow exponentially there will be huge problems, the government made a law that allowed the families to have only one child (though there were exceptions), and only a few years ago it was allowed that the families can have two children. While this has solved the problem with the rapid population growth, it opened up another, the population is aging quickly.

How is Marble formed?
Answer:
Marble is a type of rock. It is a metamorphic rock , which means rock which as changed it texture or shape or color over the time. These rocks are formed usually by uniting already existing substances on the earth. Limestone is the naturally available stone , which when undergoes metamorphosis turns into the formation of marble. Marble forms when the hot magma heats the limestone , the heat recrystallizes the calcite in the limestone changing its texture, shape etc.

Why is it incorrect to say that the earths crust is covered with tectonic plates
Answer:
The statement that the earth's crust is covered by tectonic plate is considered as false. The earth's crust as an upper mantle and inner layer of the crust. The tectonic plates always move over the mantle and does not stay constant. Hence the earth crust is not covered by tectonic plates.Answer: Ask your teacher for help

Which of these is not an advantage of wetlands?
Group of answer choices
recharge water tables
help prevent flooding
flow rapidly
good habitat for life
Answer: Low rapidly
Explanation:
Wetlands are areas that are filled with water sometimes permanently, sometimes seasonally. They have a couple of advantages such as recharging water tables, preventing flooding and providing a good habitat for life.
They recharge the water table by collecting water then letting it sip into the ground mostly at the edges. They prevent flooding by also collecting water then letting the water out gradually. They provide a good habitat for life as wetlands are teeming with fish, animal and plant life.
A rapid flow is therefore not an advantage of wetlands.
What is the main role of earths atmosphere
Answer:
Gases in the atmosphere surround Earth like a blanket. They keep the temperature in a range that can support life. The gases keep out some of the Sun's scorching heat during the day. At night, they hold the heat close to the surface, so it doesn't radiate out into space.
