• Weather is short-term, climate is long-term

• Weather is determined by humans, climate is natural

What determines Earth's average temperature?

• The number of trees on Earth

• The amount of sunlight absorbed

• The amount of rainfall

• The presence of animals

What causes ocean currents?

• The presence of fish

• Human activities

• Wind patterns and Earth's rotation

• The temperature of the water only

Which factor does NOT shape regional climate?

• Population density

• Latitude

• Altitude

• Proximity to oceans

What is a key process involved in climate change?

• Changes in temperature and precipitation patterns

• Decreased plant growth

• Increased animal migration

• More frequent earthquakes

What is the Greenhouse Effect?

• Trapping of heat by greenhouse gases

• Absorption of sunlight by the ocean

• Cooling of the Earth’s surface

• Reflection of sunlight by ice

What happens to warm air in the atmosphere?

• It disappears

• It stays at the same level

• It sinks and warms

• It rises and cools

What is one effect of climate change?

• Decreased ocean levels

• Less sunlight reaching the Earth

• Increased frequency of extreme weather events

What happens when air rises and cools?

• It releases moisture as precipitation
