Quaternary
What is the Quaternary period divided in to?
Holocene and Pleistocene
What is the current interglacial period known as?
Holocene
What is another name for the Holocene?
Age of Man
A time of warming possibly caused by climate changes
Medieval warming
A period of time when there were colder winters than those of the 20th century
Little ice age
What time period is made up of glacial and interglacial periods?
1|Page
,Pleistocene
The cyclical movement related to earth's orbit around the sun
Milankovitch cycles
What affects the amount of heat on the earth's surface and influences climate patterns?
Milankovitch cycles
What are the 3 types of Milankovitch cycles?
Eccentricity, obliquity, and precession
A type of Milankovitch cycle where earth's orbit is an ellipse and a complete cycle take round
100,000 years
Eccentricity
A type of Milankovitch cycle that deals with the axial tilt of the earth and takes 41,000 years to
complete
Obliquity
A type of Milankovitch cycle where earth's axis wobbles like a top and is caused by tidal forces;
takes 26,000 years to complete
Precession
Glaciers make up _____% of the earth's land surface
11%
What type of glaciers are found in coastal regions with high moisture?
Humid-maritime glaciers
What type of glaciers are found in continental interior areas with dry atmospheric conditions?
Dry-Continental Glaciers

, Where is snow deposited when forming glaciers?
Accumulation zone
What is the snow that has not yet been compressed in to ice that accumulates to form glaciers
called?
Firn
Where seasonal melt and transportation of seasonal ice occurs
Ablation zone
The lower limit of any year's permanent snowfall that separates the zone of accumulation and
ablation
Snowline
When ice melts more quickly than snowfall can accumulate
Glacial retreat
When snow adds more to a glacier than melting and sublimation remove and the total volume
of the glacier increases
Glacial advance
Occurs when the rate of accumulation equals the rate of sublimation
Stagnant glacier
Permanent deformation due to pressure and the primary way glaciers move
Plastic flow
When glaciers break instead of flow and occurs in cracks and crevasses of a glacier
Brittle flow
The act of a glacier sliding over the bed due to meltwater under ice acting as a lubricant
