根据短文内容，回答下列问题(每题答案不超过10个词)。
(2025·扬州模拟)There are many different types of landforms. Landforms are natural features on the planet's surface. You probably know about some of them already!
Deserts are one kind of landform that humans dislike. They are large areas of land that do not receive a lot of rainfall. Each desert has one thing in common：it has less than 10 inches of rain per year. They can be very hot during the day， and very cold at night. It is difficult for many plants and animals to live in deserts.
Mountains are very tall landforms. They are larger than hills， usually more than 600 metres high. 20% of the Earth's surface is covered by mountains. They are made up of earth and rock material. Most mountains we know about rise high above the ground， but mountains also lie under the oceans. Mountains are home to different types of plants， animals and even people. The higher the mountain you go up， the colder the temperature becomes. The air at the top of a mountain is thin， so sunlight gets through very easily. This means that even if it feels cold， you can get sunburnt quickly.
Valleys are the spaces between mountains. Some valleys are V-shaped， and some are U-shaped. Many people live in valleys， because they have a comfortable temperature， are protected， and may have rivers flowing through them. River valleys are attractive for humans as they provide good water for drinking and agriculture. They also offer benefits such as fishing， rich soil， and easier transportation.
Plains are large， flat areas of land. Since flat land is easy to build on， many cities are on plains. Many plants can grow on plains as well. Some plains are by oceans， and are called ocean plains. Plains that are by rivers are called river plains， and are especially good for growing crops.
