Question

1. why is the land in the canadian shield often rocky and uneven? a. glaciers scraped away the soil b. frequent earthquakes c. recent volcanic activity d. strong ocean currents

Explanation:

To determine why the Canadian Shield's land is rocky and uneven, we analyze each option:

• Option A: Glaciers during the last ice age scraped away the overlying soil and sediment, exposing the hard bedrock, which makes the land rocky and uneven.
• Option B: The Canadian Shield is not known for frequent earthquakes as its tectonic activity is minimal now.
• Option C: Volcanic activity in the Canadian Shield is not recent and not the main reason for its rocky, uneven terrain.
• Option D: Ocean currents do not affect the landform of the Canadian Shield (a large continental region) in this way.

So the correct answer is A.

Answer:

A. Glaciers scraped away the soil
