which of the following is true characteristic of the earth but not the moon? a. volcanoes b. plate tectonics c. molten core d. asteroids impacts

The characteristic of plate tectonics is only true about the Earth and not the Moon.

Explanation:

The Moon is way too smaller than the Earth and has a comparatively cooler mantle. The size of the Moon limits the possibility of the existence of tectonic plates. Moreover, a cooler mantle doesn't favour the generation of convection currents that are responsible for the tectonic activities. The moonquakes (like that of earthquakes on Earth) are believed to be caused by the Earth's gravitational influence over the moon and the tidal activities on Earth, not by tectonic activities.

Answer: B.

The Moon's Mantle is too cold to move easily, and has no convection and no active tectonic plate motions, due to the Moon's smaller size and colder temperature than the Earth.
