World Geo. Unit 1: Physical Systems

What 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

For the Northern Hemisphere it experiences summer starting in which month ​ (a)   ​ and for the Southern Hemisphere it experiences summer starting in ​ (b)   .

• April
• September
• March
• May
• June
• December

For the Northern Hemisphere it experiences winter starting in which month ​ (a)   and for the Southern Hemisphere it experiences winter starting in ​ ​ (b)   .

• December
• June
• September
• April
• August

Why do both hemispheres experience seasons at different times?

• They are at different distances from the sun

• They have different temperatures

• They are tilted at different angles to the sun

• They rotate at different speeds

The Northern and Southern Hemispheres experience opposite seasons.

• True

• False

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 would happen if the Earth's axis were not tilted?

• There would be no night and day

• There would be no seasons

• There would be extreme weather

• The Earth would stop rotating

Which physical process is responsible for the formation of islands and volcanos around the Ring of Fire?

What type of climate does the Sahel region primarily experience?

• Semi-arid

• Tropical rainforest

• Arctic

• Mediterranean

What significant climatic challenge does the variability of rainfall in the Sahel lead to?

• Consistent agricultural success

• Periods of drought or flooding

• Permanent ice coverage

• Abundant freshwater sources
