progressive cooling of earths surface.
earths heat balance could change as orbit alters.solar radiation fluctuations, periodic changes in earth tilt and orbit.
loss of heat from earths surface through reduction of carbon dioxide content of atmosphere.
volcanic eruptions, short term cooling of globe could increase effect if lots erupted over longer periods of time.

What caused the glacial grooves?
Glacial grooves are caused by the ice picking up boulders and scraping them across the bedrock.
What is the difference between glacial erosion and water erosion?
Glacial erosion is caused by ice, while water erosion is caused by liquid water.
Which type of erosion is caused by moving masses of ice?
The type of erosion that is caused by moving masses of ice is called glacial erosion.
Is the climate currently considered to be in an ice age?
Technically, yes. Ice ages are not continuous periods of cold, but rather have cycles of colder glacial periods and warmer interglacial periods. We are currently in an interglacial period.
What rocks are caves made of?
Caves caused by volcanic activity are made of basalt Caves caused by dissolution due to groundwater are formed in limestone or sometimes marble. Caves also form in glacial ice due to melting. (Glacial ice can technically be considered rock.)
Are glacial periods caused by changing in the tilt of the Earth's axis?
They can be. Atmospheric changes, location of continents, and solar output could also cause them.
What caused the glacial grooves?
Glacial grooves are caused by the ice picking up boulders and scraping them across the bedrock.
What is a Periods of rapid glacial movement are referred to as?
Periods of rapid glacial movement are referred to as glacial surges. These events are characterized by a sudden increase in glacial velocity, resulting in the movement of large quantities of ice over short periods of time. Glacial surges can drastically reshape the landscape and contribute to changes in local ecosystems.
What is the difference between glacial erosion and water erosion?
Glacial erosion is caused by ice, while water erosion is caused by liquid water.
Which type of erosion is caused by moving masses of ice?
The type of erosion that is caused by moving masses of ice is called glacial erosion.
How many glacial periods have there been during the last two million years?
There have been multiple glacial periods, known as ice ages, during the last two million years. These ice ages are characterized by intervals of cold climate when ice sheets covered much of the Earth's surface. The exact number of glacial periods can vary depending on the scientific definition used.
What causes glacial groove?
Glacial grooves are caused by the ice picking up boulders and scraping them across the bedrock.
What type of erosion is caused by moving masses of ice?
glacial
How was long island formed?
It was caused by deposition. Of glacial moraine.
What is another word for glacial episode?
Glacial periods, episode of glaciation, glacial age, etc. They all the same thing as an Ice Age. If you want something more specific, I would check websites that have information on weather and climates.
Is the climate currently considered to be in an ice age?
Technically, yes. Ice ages are not continuous periods of cold, but rather have cycles of colder glacial periods and warmer interglacial periods. We are currently in an interglacial period.
