what happens at a convergent plate boundary? earth's rock plates grow denser, earths rock plates slide past each other, earths rock plates collide with one another, or earths rock plates pull away from each other
At a convergent plate boundary, Earth's rock plates collide with one another.
At a convergent plate boundary, Earth's rock plates collide with one another. Convergent boundaries occur when two tectonic plates come together, leading to a variety of geological features and processes. The collision can result in the formation of mountains, volcanic activity, and the creation of deep trenches. The denser plate usually subducts, or goes under, the less dense one, leading to the recycling of Earth's crust and the formation of new landforms.
At a convergent plate boundary, the Earth's rock plates collide with one another. However, let me explain how you can arrive at this answer yourself.
To determine what happens at a convergent plate boundary, it helps to understand the different types of plate boundaries:
1. Convergent Boundaries: Occur when two plates come together.
2. Divergent Boundaries: Happen when two plates move away from each other.
3. Transform Boundaries: Take place when two plates slide past each other horizontally.
Now, considering the options you provided:
1. Earth's rock plates grow denser: This statement doesn't accurately describe what happens at a convergent plate boundary. The density of the plates may vary, but it is not directly related to what occurs at these boundaries.
2. Earth's rock plates slide past each other: This statement describes what happens at a transform boundary, not at a convergent plate boundary. In transform boundaries, plates move horizontally, causing earthquakes.
3. Earth's rock plates collide with one another: This correctly describes what happens at a convergent plate boundary. When two plates converge, they collide, leading to various geological phenomena such as mountain formation, volcanic activity, and the creation of deep ocean trenches.
4. Earth's rock plates pull away from each other: This statement applies to divergent plate boundaries, not convergent ones. In divergent boundaries, plates move apart or separate, creating gaps called rift zones.
Therefore, the correct answer is that at a convergent plate boundary, Earth's rock plates collide with one another.
