Deserts

Map of deserts

Deserts Who- people actually do live in the deserts and adapt well to the heat these people are usually nomads or sometimes even hunters and gatherers What- A desert is a big plain area with usually very high in temperature and rarely water, possibly even none. Where- Many deserts are found in bands along 30 degrees latitude north and 30 degrees latitude south. When- I can’t see when exactly it rains in the desert but it rains less than 200mm per year. Why- why are deserts so hot? It’s mostly because of the lack of water. And there is less moisture in the air. How- when trees are cut down, there are no tree roots to hold the soil in place. This means wind erosion can pick up more good topsoil and take it away.

Rivers

Who- Many different types of plants and animals grow and live along a river’s banks, including trees, shrubs, birds, and insects. What- definition: A large natural stream of water flowing in a channel to the sea, a lake, or another stream. Where- Rivers are mostly found where there has been a big melt like a glacier or at a natural spring. When- Rivers overflow when the volume of water is greater than the capacity of the river banks. Why- river flow downhill toward a sea or ocean. How- rivers are formed from small erosions making a narrow channel then water falls and flows down that channel.

MOUNTAINS

mountains Who- New Zealander Edmund Hilary was the first person to reach the top of mount Everest. What- In terms of Mountains with public ski areas - Mt. Hood's Timberline Lodge generally gets some of the highest snow totals each year. Where- They start under the ocean and come up when the plates come together. So they form under the ocean When- when do mountains stop moving? Mountains never stop growing. Why- why do mountain tops have snow? ground absorbs more heat than high altitude places and that causes the air to be actually not so hot on high places. How- how are mountains are formed? There are actually several ways that mountains are formed, and they all have to do with processes that take millions of years.
