Practice Test 8

Read the passage: In fall, days get shorter and cooler. Because there is less sunlight, many trees stop making new leaves. As a result, leaves change color and then fall off. After the leaves fall, the tree rests through winter. When spring comes and days get longer, new leaves grow again. Why do many trees stop making new leaves in fall?

Read the passage: In winter, the air can get very cold. When the temperature drops below freezing, water turns into ice. Because ice is hard, puddles and ponds can freeze on top. As a result, animals may walk carefully and people may wear boots. When the air warms up again, the ice melts back into water. What happens when the temperature drops below freezing?
