Earth Processes - Unit 7 Review

The data chart shows the length of the shadow of an object outside at different times of the day. 

What would most likely be the measurement of the shadow at 1p.m.?

• 5 cm

• 11 cm

• 8 cm

• 4 cm

What phenomena does this diagram demonstrate?

• The Earth's revolution, which takes 365 days.

• The Earth's rotation, which takes 24 hours.

• The Earth's revolution, which takes 24 hours.

• The Earth's rotation, which takes 365 days.

The pictures below show a tree at noon and at sunset on the same day.

Which sentence explains the differences in the shadows at these two times?

• The shadow changes because the sun sets in the West changing the length of the shadow in the East.

• The shadow changes because the sun sets in the East changing the length of the shadow in the West.

• The shadow changes because the sun is brighter at sunset.

• The shadow changes because the sun is brighter as sunrise.

A scientist used blocks, a ramp, and a car to complete an investigation. The scientist used the same car and ramp each time. However, as the variable in this investigation, he increased the number of blocks under the ramp with each experimental trial to change the height of the ramp. How many variables should be tested in an experiment?

• 1

• 2

• 3

• 4

One sunny day, a class measured and recorded the length of a flagpole during the morning.

What will happen to the length of the shadow in the afternoon hours?

• The length will continue to decrease because the Sun appears to be higher in the sky.

• The length will gradually increase because is the Sun appears to be sinking lower in the sky.

• The length will increase and then decrease again because the Sun is always moving.

• There will be no shadow visible because it is a sunny day.

The Earth’s rotation results in the day and night cycle causing the apparent movement of the Sun across the sky. Therefore, the Sun rises in the east and sets in the west.

How many hours does it take the Earth to complete one day and night cycle?

• 12

• 365

• 28

• 24

In the picture, the Sun’s position is making a shadow.

Using the compass rose and the Sun’s position, what time of day is pictured?

• It is early morning because the Sun is in the east and there is a long shadow. 

• It is late afternoon because the Sun is in the east and there is a long shadow. 

• It is late morning because the Sun is in the north and there is a short shadow. 

• It is early evening because the Sun is in the west and there is a short shadow.

What could be done to make this diagram more accurate?

• Replace the Sun with the Moon because the Sun sets in the West.

• Switch the East and the West because the Sun rises in the East.

• Add clouds to the drawing so it's prettier.

• Move the Sun directly above the house to decrease the shadows.

• Change the time from 6:00 AM to 6:00 PM because the Sun sets in the West.
