Question

what natural process significantly shaped continent - wide landforms? options: ocean waves, random horizontal movements, volcanic activity, climate change
how do the rocky mountains influence north american geography? options: create a national barrier, impact continental climate, determine animal patterns, all of the above
what defines a peninsula, a geographical formation? options: land completely surrounded by water, land mostly surrounded by water, mountainous terrain, desert region

Explanation:

1. For the first question about natural processes shaping rock - sediment generation, weathering breaks down rocks into sediments. Erosion transports them, and deposition accumulates them. But weathering is a key initial process.
2. For the second question, the Rocky Mountains influence North American geography in multiple ways. They act as a natural barrier, affect continental climate by blocking moisture - laden winds, and influence animal migration patterns.
3. For the third question, a peninsula is a landform that is surrounded by water on three sides.

Answer:

1. Weathering
2. All of the above
3. Land partially surrounded by water
