Question 2

Moraines are composed of jumbled piles of very poorly sorted rock fragments ranging in size from boulder to clay that fall out near the edges of glaciers.Why are the larger particles (boulders,etc.)not broken down during transport in the glacier?

Accepted Answer

A) because the ice is not strong enough to break up rock 
B) because sediments are picked up and carried along with the ice as it moves 
C) because the sediments are not carried for very long distances 
D) because the ice stops the chemical weathering processes

Question 4

Glacial ice cores can be used to determine the atmospheric concentration of CO₂ during Earth's history.How do scientists come up with these data?

Accepted Answer

A) They use the thickness of the ice layers to determine how much CO₂ was in the atmosphere. 
B) The melt the ice and measure how much carbon was trapped in the ice. 
C) They record changes in the shape of ice crystals to determine the paleoclimate. 
D) They break the ice apart,release the air trapped in bubbles,and then measure the gases.
