The water droplet will turn into rain because it is precipitation.
The water droplet will begin to condense and form a new cloud.
A student wants to draw the impact of the water cycle. Water is a clear, colorless, tasteless and odorless liquid that makes up seas, lakes, rivers and rain.

What information should the student include to describe how a drop of water from Georgia can end up watering a forest in China?
The water cycle is a cycle that is constantly changing. The water will evaporate towards China.
This is impossible because water will evaporate, condensate in the clouds, and rain in the same area.
The water cycle is not limited to one area. The water will be pushed by winds when it becomes clouds.
The water cycle is a cycle that travels across the world in one day. Whenever water evaporates, it will quickly condensate and travel across the world.

Which of the following is a way that the student’s argument can be improved?
The student should not say that the tilt of the Earth causes the seasons.
The student should not say that direct and indirect sunlight causes the seasons.
The student should add the Earth’s orbit around the sun to the argument.
The student should add the Earth’s distance from the moon to the argument.
Students are given the following image to try to figure out which season is represented in the images and provide evidence for their explanation.
Which of the following explanations BEST describes the seasons shown?
Image A represents the summer months because there are direct rays of sunlight.

The stars appear bigger and brighter because of their closeness to the Earth.
The stars appear bigger and brighter because of their closeness to surrounding stars.
Use the information to answer the following question.
During recess, Tony and Josephine were talking about the sun and stars. Tony told Josephine that the sun is really a star. Josephine asked why it was so big and bright.
If the sun is a star, why is it so big and bright?
The sun is not really a star. It is a sun and that’s why it is so big and bright.
Since the sun is the closest star to the earth, it appears bigger and brighter than the other stars.
The sun is brighter than all the other stars in the sky, so it looks bigger from the earth even though it is really farther away than most stars.
The sun is a star, but it is made up of gasses that are much different from the other stars, and this makes it appear bigger and brighter than the other stars.
