Florida state university has a large collection of ice cores taken from the antarctic. what can scientists learn by studying these ice cores?
group of answer choices

a history of earth’s climate

b how new species have evolved

c how continents have moved

d major changes that have taken place on earth’s surface

A and D

Explanation:

Through analysis of ice cores, scientists learn about glacial-interglacial cycles, changing atmospheric carbon dioxide levels, and climate stability over the last 10,000 years. Many ice cores have been drilled in Antarctica. Antarctic ice core drill sites with depth and record duration.

As snow is layered it compresses, and over time the lower layers are turned into ice, capturing small samples of the atmosphere as air bubbles. These natural ice archives with trapped chemicals, dust and air, can hold a a tremendous amount of information for scientists. Past climates and temperatures, large scale Earth events such as volcanic eruptions, atmospheric changes, ice accumulation rates over time, changes in vegetation and human impacts on the overall Earth system through emissions of gases and chemicals are all information that is captured in ice cores.

b. 20: 5

explanation:

20% of the worlds population lives in southwest asia, and less than 5% of the world's

land area.
