Desiertos

Deserts are areas receiving less than 250 L of rain per square meter annually. They form in four main regions: subtropical, orographic shadow, cold ocean currents, and polar regions. Subtropical deserts like the Sahara form due to dry air from the equator. Orographic shadow deserts, such as the Gobi, are created by mountain rain shadows. Cold ocean currents lead to deserts like the Atacama in Chile. Polar deserts, like Antarctica, form due to low solar heat. Despite their differences, all deserts share dryness as a common trait.

What is the primary reason for the formation of deserts in the subtropics?

• Frequent storms

• Proximity to oceans

• Dry air from the equator

• High humidity levels

Which desert is the largest hot desert in the world?

• Sahara Desert

• Antarctic Desert

• Atacama Desert

• Gobi Desert

How do orographic shadow deserts form?

• By being near cold ocean currents

• Through volcanic activity

• Due to high temperatures

• From mountains blocking rain

What natural feature contributes to the formation of the Atacama Desert?

• Proximity to the equator

• Dense forests

• Cold ocean currents

• High altitude

Why is Antarctica considered the driest continent?

• Water vapor freezes due to low heat

• It is covered in ice

• It has no rainfall

• It is surrounded by mountains
