World Geo. Midterm Review

How does the tilt of the Earth affect climate?

• It has no effect

• It determines the intensity of sunlight received

• It regulates ocean currents

• It affects wind patterns

What primarily causes the change in seasons on Earth?

• The distance from the sun

• The tilt of Earth's axis

• The shape of the Earth

• The rotation of the moon

Match the following

What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time
• Continents are stationary and do not move
• The Earth is broken into lithospheric plates that move due to convection currents
• none of the above

What is desertification?

• The process of deserts shrinking

• The process of deserts growing into non-desert areas

• The process of deserts remaining the same size

• The process of deserts becoming wetter

Which of the following is a climatic factor contributing to desertification?

• Increased rainfall

• Decreased temperatures

• Increased humidity

How can human activities contribute to desertification?

• By planting more trees

• By cutting down plants and over-farming

• By conserving water sources

• By reducing soil erosion

What are some signs of desertification?

• Increased water levels

• Decline in agriculture and increased erosion

• More native plants
