........ ......... show the changing climate because every year a new ring is formed. The wider the ring, the higher the temperatures that year.

How do ice cores show that the climate has changed.

• The layers of ice get thicker for warmer weather

• The layers of ice get thinner for warmer weather

• There are more gas bubbles in the ice layer for warmer weather

• There are more fossils in the ice layer for warmer weather

What are the Milankovitch cycles?

• The change in the earths orbit from circular to oval every 100,000 years

• The change in the earths orbit from circular to oval every 11 years.

• The increase in CO2 every 100,000 years.

Sunspots change every 11 years. The more sunspots the warmer the temperature. Is this a natural or a human cause of climate change.

• Because the trees create wind which cools down the planet.

• Because the trees produce oxygen.

• Because the trees provide shade.

• Because the trees absorb carbon dioxide.

What is the enhanced greenhouse effect.

• Increased amounts of greenhouse gas release solar energy.

• Increased amounts of greenhouse gases trap more solar energy.

• Increased amounts of greenhouse gases trap more CO2.

• Increased amounts of greenhouse gases trap more pollution
