How are the sun, Earth, and moon aligned during a lunar eclipse?

• In a straight line with the moon between Earth and the sun

• In a straight line with Earth between the sun and the moon

• With the sun and the moon at right angles to each other in relation to Earth

• With the sun and Earth at right angles to each other in relation to the moon

Which of the following happens during a lunar eclipse?

• Earth starts revolving around the moon.

A coastline on Earth experienced a high tide at 6 a.m. At what approximate time will the next low tide occur, and why?

• 6 p.m., because the coastline will turn 90 degrees from the moon

• 6 p.m., because the coastline will turn 180 degrees from the moon

• 12 noon, because the coastline will turn 90 degrees from the moon

• 12 noon, because the coastline will turn 180 degrees from the moon

High tide are experienced 12 hours apart for a certain coastline. Which of the following best explains the reason for this phenomenon?

• The coastline experiences tidal bulge twice a day.

• The coastline experiences tidal bulge once a day.

• The coastline comes in a straight line with the moon once.

• The coastline becomes 90 degress with the moon twice.

During a certain time of the year, location B receives light rays spread out over twice as much area as location A. Which of the following explains which location is relatively cooler than the other?

• Location A, because it receives sunlight at a smaller angle than location B

• Location B, because it receives sunlight at a smaller angle than location A

• Location A because it receives sunlight at a 90° angle

• Location B, because it receives sunlight at a 90° angle

During a certain time of the year, the angle of the sun's rays at location C is smaller than the angle of the sun's rays at location D. Which location experiences cooler temperatures at that time?

• Location C, because the smaller angle means the sunlight is spread out over more area

• Location D, because the larger angle means the sunlight is spread out over more area

• Location C, because Earth is tilted away from the sun at this time

• Location D, because Earth is tilted towards the sun at this time
