Exam 6: Earth and Its Moon: Our Cosmic Backyard

The crust on the near side of the Moon is on average thinner than the crust on the far side, due to our tidal pull on the Moon.

What is true of the lunar highlands?

In most places on the seacoast, there are two high and two low tides a day.

When strong solar wind storms are diverted poleward by our magnetic fields, we often observe in the ionosphere.

Neap tides occur at first and third quarter phases of the Moon.

Why is the impact theory now preferred as an explanation for the Moon's origin?

Seismic P- waves can be detected worldwide from any strong epicenter.

The Earth's inner core is about the same temperature as the surface of the Sun.

has the largest gravitational pull on Earth.

Which of these age ranges best describes the lunar maria?

What is meant by tidal locking?

List the two major regions of the near side of the Moon, as seen with the naked eye.

The difference in the Moon's gravitational force on the near and far sides of the Earth produces a(n) _ .

At what phase are the tides least noticeable?

The ozone layer blocks much of the Sun's radiation.

The lunar mare are found

Because the interior of the Earth is , the crust is much less dense than the core.

Today, an average lunar moonquake releases about as much energy as
