A colder climatic period of glacial advance.

• Glacial period
• Interglacial period
• Glaciated
• Global cooling

 A warmer climatic period of glacial retreat.

• Glacial period
• Interglacial period
• Glaciated
• Global warming

A large mass of moving ice.

• Iceberg
• Glaciated
• Glacier
• Avalanche

The change of the shape of the Earth’s orbit from nearly circular to elongated and back again.

• Precession
• Tilt
• Angle
• Eccentricity

The wobble of the Earth’s axis.

• Precession
• Eccentricity
• Tilt
• Angle change

A period of climatic cooling during which glaciation repeats.

• Glacial period
• Ice age
• Interglacial period
• Global cooling

To be covered in ice sheets or glaciers.

• Glaciered
• Ice buried
• Glaciated
• Ice sheet

What is the principle behind the Milankovitch theory?

• The amount of solar radiation that Earth absorbs is constant
• The amount of solar radiation the sun receives varies
• The amount of solar radiation the sun receives is constant
• Cyclical changes in the Earth's orbit and the tilt of the Earth's axis cause climatic changes

How do glacial and interglacial periods differ?

• In glacial periods, glaciers advance; in interglacial periods they retreat
• In glacial periods glaciers flow; in interglacial periods they advance
• In glacial periods, glaciers retreat; in interglacial they slip
• In glacial periods glaciers retreat; in interglacial they advance

What happened to sea levels during the last ice age?

• They were the same as today
• They were higher than today
• They were lower than today
• They were higher, then lower than today
