Exam 16: Earth and Moon: Bases for Comparative Planetology

Human output of carbon dioxide is small compared to natural output by volcanoes, for example.

On the Moon, the maria are younger than the highlands.

The presence of vesicular basalts among the lunar rock samples shows that

Explain how a greenhouse works.

The Earth is about ___________ years old by ___________.

In the condensation theory of the Moon's origin,

What causes erosion

Fragmenting during meteorite impacts caused the vesicular basalts found among the lunar samples.

Earth and the Moon could not have condensed from the same materials because they have different densities and compositions.

The four stages of planetary development are shown above. Which is the last one

Motion of the plates of Earth's crust is thought to be due to

The greenhouse effect occurs because carbon dioxide is opaque to infrared radiation.

The Moon's distance from Earth is measured very accurately by bouncing a laser beam off of a small mirror left on the surface of the Moon. If a laser is fired at the Moon and the signal returns in 2.6 seconds, what is the distance to the Moon

Slow surface evolution is caused by

-The four stages of planetary development are shown above. Which is the first one

The Earth is geologically dead and the Moon is geologically active.

When plates spread apart and magma rises, what forms in the following labeled map of Earth

On Earth, according to current ideas about plate tectonics, ____________ were once together.
