The Sun's energy causes changes on Earth. Which of the following is a change caused by the Sun?
The Sun's energy is reflected off high mountains, causing cold temperatures.
The Sun's energy heats the Earth, contributing to evaporation.
The Sun's energy causes lava to boil and erupt from volcanoes.
The Sun's energy melts snow crystals in clouds, causing rain.
What process in the water cycle occurred to form the object at location B in the diagram?
Condensation
Precipitation
Evaporation
Runoff
The pictures show a sidewalk at three different times on the same day. The changes were caused by the weather. Which table best describes the changes that most likely occurred between 6:00 A.M. and noon?
The picture shows water droplets on a blade of grass in the early morning hours. Tiny drops of water that form on cool surfaces overnight are called dew. What process is most likely causing the water droplets to form on the grass?
evaporation
weathering
condensation
runoff
During a science lesson, a teacher placed a beaker with 50 mL of water near a sunny window. He placed another beaker with 50 mL of water in the closet. Two days later, the beaker near the window was empty while the water remained in the beaker that was placed in the closet. What most likely happened to the water in the beaker near the window?
The Sun changed the water from a liquid to a solid.
The Sun's light caused the water to condense.
The water changed from a gas to a liquid.
Heat from the Sun caused the water to evaporate.
Which process of the water cycle is shown above?
precipitation
evaporation
condensation
transpiration

Mrs. Brown's class is studying how the path of the Sun crossing the sky changes during the day. Each hour a pair of students goes outside to a square Mrs. Brown has painted on the sidewalk. One student stands a ruler upright in the center of a painted square. The second student traces the shadow produced by the ruler onto a piece of paper. This picture is then posted in the classroom beside the picture made the hour before. At what time will the shadow be shortest?
9:00 AM
10:30 AM
12:00 PM
2:30 PM
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.
A Sun-Earth cycle is pictured. What is the correct order of the seasons as they occur from March through December?
Spring, Winter, Autumn, Summer
Spring, Summer, Autumn, Winter
Summer, Winter, Autumn, Spring
Winter, Spring, Summer, Autumn
