Question 187 (1 point) Coring can create climate logs than span from hundreds to millions of years (choose the best answer) Tundra Ice sheets Igneous rocks Ocean sediments Bogs and marshes Question 188 (1 point) In 1831, the North Magnetic Pole was located over Northern Nunavut. Which direction has it migrated in since then?

Answer 1

Ice sheets and glaciers near Earth’s North and South Poles formed from years and years of accumulating snowfall. The weight of each year’s snowfall compresses down the previous layers of snow, and after many years, all of this pressure helps to form glacial ice. In some areas, these layers result in ice sheets that are several miles (several kilometers) thick.

Researchers drill ice cores from deep (sometimes more than a mile, or more than 1.6 kilometers) inside the polar ice sheets in Greenland and Antarctica, as well as some high-latitude ice caps and mountain glaciers. They collect ice cores in many locations around Earth to study regional climate variability and compare and differentiate that variability from global climate signals.

So answer is ice sheets
