A because they tell by their texture.
You see how much the scale is, let's say that it is 150 mm=300 miles. If it goes over, you can measure it with a ruler, or move with your hands, measuring it as well as possible and estimating. Hope this helps! :)
The correct answer is D. ocean floor mapping and earthquake tracking
Tracking earthquakes is helpful because it shows where it came from and what caused it, as well as how it affected the environment, while ocean floor mapping is useful because it shows how the bottom of the sea changed over time which happens due to tectonic activity.
A rock on Earth's surface tends to be weathered more because it is exposed to wind, precipitation, and the effects of gravity. A rock buried underground does not experience weathering from wind, precipitation, or gravity.
