2
How does a glacier help create new soil?
by freezing small particles of soil to form large rocks
by melting rocks along its path down the valley
by carrying living plant material to the ocean
by scraping small particles of large rocks
3
Seafloor spreading provides evidence of which of the following Earth processes?

5
Which of the following are formed when two crustal plates collide with on another?

6
The "Ring of Fire" encircles the Pacific Ocean. Why are they arranged the way they are?
