Florida State University has a large collection of ice cores taken from the Antarctic. By this information scientists learns about the <u>history of Earth’s climate</u>
Answer: Option A
<u>Explanation:</u>
Ice cores which are taken from the Antarctic help the scientists to study the history of Earth's climate. With the help of these ice cores scientists can study the climate of earth as far back as 800,000 years.
This can be studied by drilling core samples from deep underneath the ice sheets of Antarctic. The records of ice core can be used to reconstruct ocean volume, precipitation, solar variability, volcanic eruptions, atmospheric dust and many other things.
Why was it almost impossible for a woman to become an astronaut?
Answer;because men are stronger,taller and weighted more.
The plate labeled with A is the South American plate, the one labeled with B is the African plate, and the one labeled with C is the Australian plate.
Explanation:
The three plates that are marked on this map are the South American, African, and Australian (Indo-Australian) plates. All of these three plates have a core of continental crust which is surrounded by oceanic crust. The three continents on these plates are South America, Africa, and Australia (plus the subcontinent of India). Despite the three continents being separated by oceans between them at present, it was not like that throughout the past.
- In the distant past these three continents were merged, being part of Gondwanaland, accompanied by India and Antarctica as well.
- Divergent boundaries arose between them though, so they started moving apart and gradually formed new continents.
- As it stands, there is no evidence that these plates will merge again in the next few million years, as the South American plate moves west, the African is actually splitting into two plates, and the Australian is moving toward northeast.

Answer: The earth layers and atmospheric layers are distinctly different.
Explanation:
The earth layers are made up of solid matter whereas the atmospheric layers are made up of gases.
The earth layers provide the base for the survival of diversity of living beings whereas the atmospheric layers only allow microbes which can survive in extreme temperature conditions.
The stratospheric layer of the atmosphere protects the living beings from the harmful radiations striking on the surface of earth and they are capable of causing mutation whereas the lithosphere or any other surface layer of the earth also absorb thermal energy from sun but does not provide protection against harmful affects of ultraviolet radiations.
