What do you remember?

Tides on Earth are influenced more by the Moon than the Sun because the Moon is

• brighter than the Sun.

• larger than Earth.

• colder than Earth.

• closer than the Sun

The orbit of the Moon is not usually in the same plane as Earth and the Sun. (See the pic)

Which of these can only take place at times when the Moon is between Earth and the Sun and in the same plane? (Hint: Draw this)

• a full moon

• a new moon

• a solar eclipse

• a high tide

What has the greatest influence on the strength of a high tide in a particular area?

(hint:

• the position of the Moon around Earth

• the position of Earth around the Sun

• the rotation of the Moon

• the rotation of Earth

The stratosphere contains ozone (O3)

which interacts with the ultraviolet radiation that reaches Earth from the Sun. How does the action of ozone in the stratosphere affect Earth?

• Ozone is essential for living organisms to breathe.

• Ozone maintains the magnetic field around Earth.

• Ozone stores heat to be transferred to the surface of Earth.

• Ozone removes electromagnetic radiation that is harmful to living things.

At the same latitude, the climate tends to be colder in the mountains than at sea level. Which explains the difference in temperatures at different elevations?

• Precipitation absorbs heat at lower elevations.

• Air molecules are farther apart at higher elevations.

• Heat radiated from Earth creates wind at lower elevations.

• Lack of vegetation at higher elevations keeps the air cooler.

Most ultraviolet (UV) rays are deflected or absorbed by the atmosphere, but some of these rays pass easily through the atmosphere and penetrate Earth’s surface.

Which substance in the atmosphere absorbs most of the ultraviolet rays?

• chlorofluorocarbon

• ozone

• nitrogen

• water

A low tide and a high tide occur in the oceans two times each day. Which factor has the greatest effect on the size of the tides?

• air pressure differences

• gravitational pull from the Sun

• seasonal temperature variations

• gravitational pull from the Moon

Ocean tides result mainly from

• surface winds.

• radiant heat from stars.

• Earth’s tilt on its axis.

• the Moon’s gravitational pull.
