Answer:

The best way to determine whether a planet has crust composed of plates that move is if it has chains of volcanoes along continental coastlines.

Explanation:

A is not correct because the condition of the water depends on the temperature of the planet and its atmosphere.

B is not correct because the iron-rich rocks may just be an ancient remnant of volcanic activity, but in general, it is the most common metal found in the crust, so it is not a good indicator.

C is correct because the chains of volcanoes along the coastlines indicate that there are subduction zones, meaning that there are tectonic plates that move.

D is not correct because the deep chasms carved by meteors are not in any way connected to the tectonic activity.

Which example BEST shows the global impact of the Internet? An American writer uses the Internet to conduct research for a repor
Fudgin [204]
I believe the answer is:
- A Chilean reporter shares live footage of an earthquake on the Web.

This is a perfect example of the power of the internet, where we have a country that is very far away and something happens in there and by using the internet you can visually see what is happening there in the exact same moment even though you may be on the total opposite side of the world.
