Answer:
e. To create valleys, glaciers have to be constantly advancing.
Explanation:
Although glaciers look like massive, solid blocks of ice, they actually move in a very slow manner, which is difficult to detect by the naked eye. The pressure that the glacier receives from the weight of the ice causes it to deform. As these changes occur, the melt water at the bottom of the glacier allows it to slide. It is this movement that allows for the formation of glaciers, as glaciers have to be constantly advancing in order to form valleys.
I'd have to say gas because it usually doesn't change at all
Elevation= height (how high?)
if you see the letters c and d on he picture, how many meters is in between??
Answer:
1) Climate change in the last 100 Myr. has been extreme, thus offering a potential explanation of Earth's <u>TRUE</u>
Explanation:
2) Orbital forcing (changes in Earth's axis tilt) are too insignificant in the last 25,000 yrs. to explain Earth's warming in the past 125 years. <u>FALSE</u>
3) Retreat of glaciers in the past 8000 years has been uniform, thus potentially explaining Earth's warming in the past 125 years. <u>FALSE</u>
