5.3 - Changes in Climate

Many animal species, such as mammoths and scimitar-toothed cats, became extinct at the end of the last ice age. Why?

• These animals adapted to become totally new species

• They decided to die

• Their bodies were better suited to live in colder climates

• There were too many food sources that they died from over-eating

The width of _________________________ helps scientists learn about temperatures and precipitation long ago.

• Tree Rings

• Ice Cores

• Fossil

• Pollen

What has affected the severity of major ice ages?

• Changes in the angle at which Earth’s axis tilts and the shape of the orbit

• The movement of continents together affect wind patterns and ocean currents

• The increase in yearly volcanic eruptions

• The changes in the amount of light given off by the sun

Which statement is not correct regarding how the movement of continents affect changes in climate over millions of years

• Latitudes and temperatures have changed.

• Mountains formed.

• The angle at which Earth's axis tilts and the direction of the axis

• Global patterns of winds and ocean currents changed.

Scientists analyze __________ found in lake bottoms to learn what type of plants lived there thousands of years ago.

• Tree rings

• Pollen

• Ice Cores

• Fossils

How does a volcanic eruption affect climate?

• Solar radiation reaching Earth is reflected causing a drop in temperature.

• Global patterns of winds and ocean currents changed.

• Huge sheets of ice covered large parts of Earth's surface.

• The movement of continents over time changed the locations of land and sea.
