A teacher was talking with the students about earth's day and night cycle, as well as other planets in our solar system. Below are some thoughts from the students. Which ones are true statements. check all that are true.

• The revolution of the earth around the sun causes the day/night cycle.

• The rotation of the earth on its axis causes the day/night cycle.

• Days and nights have different lengths on other planets.

• At night the sun is shining on the other side of earth.

• At night the sun no longer shines on the earth.

Multiple Choice

Some ocean currents are caused by differences in the density of water from place to place around the earth. 

What two factors cause differences in the ocean water density?

• Differences in the water temperature and wind.

• Differences in the water temperature and the amount of dissolved salts.

• Differences in the water temperature and the phases of the moon.

• Differences in the amount of dissolved salts and gravity.

Match

• Tides that are at the highest and lowest levels

• Tides that do not differ much between low and high tide

High tide

• 1st or last Quarter Moon

• New Moon or Full Moon

• Spring tides

• Neap tides

• High tide

Multiple Choice

A total solar eclipse is a rare event. Why are reoccurring solar eclipses so rare?

• Because of the rotation of the moon and earth, the three rarely form a straight line.

• The light from the sun usually passes through the moon instead of being blocked by it.

• A total solar eclipse actually occurs monthly, but is only visible from the equator.

• The moon passes slightly above or below the line between the Sun and the Earth because of its tilted orbit.

Multiple Choice

Compare this image of a partial solar eclipse to that of a total solar eclipse. Which argument accounts for the difference in what you see during the partial solar eclipse?

• The Earth, Moon, and Sun are not in exact alignment.

• This view is seen when you are standing in the umbra only.

• It is not time for the full moon phase so you see the partial eclipse.

• The moon is farther away from the Earth and does not block the entire view.

Match

Match the following

• Moon is just about to cause this kind

partial solar eclipse

Total Solar Eclipse

Solar Eclipse

Lunar Eclipse

Star - massive ball of plasma

• partial solar eclipse

• Total Solar Eclipse

• Solar Eclipse

Multiple Choice

The earth moves in an elliptical orbit around the sun that requires 365 1/4 days to complete. When the earth's axis points towards the sun, it is ___________ season in that hemisphere?

• Fall

• Summer

• Spring

• Winter

Multiple Choice

A solar eclipse can ONLY occur when the moon is in which phase?

• Full Moon

• 1st Quarter

• 3rd/last Quarter

• New Moon

Multiple Choice

The graph reflects that a coastal area has two high tides and two low tides every 24 hours?

• True

• False

Multiple Choice

Both the Moon and the Sun influence tides on Earth. The moon has a much greater influence though. Why is that?

• Because the Sun is much less dense

• Because the Sun is gaseous, not solid

• Because the Sun is much farther away from Earth than the moon

• Because the Sun is less massive than the Moon

Multiple Choice

Winter in the Northern Hemisphere begins December 21 or 22, when the North Pole is tilted a full 23.5° away from the sun. This day is known as the winter solstice. The angle of the sun is the lowest and the Northern Hemisphere has the least amount of daylight. When the Northern Hemisphere is tilted toward the sun, that part of the Earth receives more direct rays of sunlight during the daytime than the Southern Hemisphere does.

During the summer, the land, oceans, and atmosphere in the Northern Hemisphere receive more direct rays of sunlight and

• it is very cold

• the days are longer

• the days and night are equal

• there is an increase in precipitation

Multiple Choice

When Earth is between the Moon and the Sun, the fully lit face of the Moon is seen from Earth. This phase of the Moon is called a ________ moon.

• crescent

• full

• new

• waxing

Multiple Choice

As the phases of the moon change, and we move from step D to C and back to A, we would say that the moon is ____________, or the view of the moon we see is getting smaller.

• waning

• waxing

• whisting

• Whittling

Multiple Choice

The temperature on land around the equator stays about the same throughout the year. This is because this area

• has a greater tilt than other parts of the Earth.

• receives less direct sunlight throughout the year.

• receives similar amounts of sunlight throughout the year.

• is flatter and absorbs heat more efficiently

Multiple Choice

In the oceans the colder water sinks into deep basins, while warmer water stays closer to the surface. The water then moves around the ocean basin. This causes

• increases, decreases

• decreases, increases

• remains the same, decreases

• remains the same, increases
