The picture below shows a cumulonimbus cloud forming over an ocean.
Which statement best explains how the sun and the ocean interact to form a cumulonimbus cloud?
A. Heat from the sun warms the ocean, causing water to evaporate. The water vapor then condenses to form a cumulonimbus cloud.

Some scientists measured and recorded local rainfall amounts and water levels at several local lakes over the summer. They compared their measurements with data from the past 30 years. The scientists concluded that the area was drier this summer than in previous years. They plan to continue recording these measurements each summer for the next decade. What characteristic of the area are the scientists studying?
A. Climate, because they are making more than one type of measurement
B. Climate, because they are comparing rainfall amounts over a long period of time
C. Weather, because they are tracking changes only to their local environment
D. Weather, because they expect rainfall amounts and water levels to continue to decrease
What is B?
Climate, because they are comparing rainfall amounts over a long period of time
