1. A student observes a large rock at the base of a volcano in a river valley that gets a lot of snow in the winter and floods in the spring. The student claims that the large crack in the rock was caused by a destructive process called weathering.
Which argument best describes the students claim?
The students claim is correct because water fills small cracks in rocks, freezes and expands, making the cracks larger over time.
The students claim is correct because the rock was carried from the top of the volcano to its based by a glacier, creating many cracks over time.
The students claim is not correct because the rock was picked up by moving water and rolled against other rocks, smoothing its surface and causing cracks in the short period of time.
The students claim is not correct because large cracks in rocks are caused when lava from a volcano covers rock so its temperature rises and falls in a short period of time, causing it to break.
