Cause and Effect - Mountains

What causes water vapor to rise into the air?

• The wind blows it upward

• The sun warms water in rivers and oceans

• Water is frozen in glaciers

• The air in mountains is colder

What happens when water vapor cools down?

• It disappears into the air

• It turns into clouds and forms small water droplets

• It melts into rivers

• It stays as water vapor

Why are some mountain animals becoming rare?

• People are moving away from mountains

• The climate is becoming warmer

• People are using more land, water, and wood

• More animals are moving into the mountains

What makes mountain valleys a good place for farming?

• They have rich soil and plenty of water

• They are far from human settlements

• They have colder temperatures

• They have strong winds

Why do farmers build terraces on mountain slopes?

• To stop animals from eating the crops

• To control the flow of water and grow crops

• To make the mountains taller

• To prevent landslides

What happens when rain falls on mountains?

• All the water stays on the mountain

• It turns into vapor immediately

• Some water is stored as snow, and some flows into rivers

• It disappears into the ground forever

Why are mountains called the “water towers” of the world?

• They store large amounts of water in the form of snow and glaciers

• They have many waterfalls

• They collect rainwater from the oceans

• They are very tall

Why does the shape of a mountain affect the water cycle?

• It prevents rain from falling

• It pushes water vapor up to the top of the mountain

• It blocks sunlight

• It makes the air hotter

What is the effect of warm temperatures on glaciers?

• Glaciers grow bigger

• Glaciers melt, causing more water to flow into rivers

• Glaciers turn into clouds

• Glaciers disappear instantly

How does building roads in mountains affect animals?

• It helps animals find more food

• It gives animals more space to live

• It takes away their natural habitat, making them rare

• It helps animals migrate to other places
