Glaciation of Canada.

Erosion: Deposition: AIM: Erosional and Depositional systems

  Glacier: thick mass of ice, forms over land  Compaction and recrystallization of snow  Glacier Types: Glacier Types:  Valley (alpine) glaciers –

Form in high mountains where snow accumulates to sufficient depths so that it is compressed, compacted and recrystallized. For this reason glacial.

Glaciers and Glacial Landforms

 As glaciers travel over land, glacial ice can erode the underlying bedrock.  This erosion can happen by:  Plucking  Abrasion.

August 3, What can geologic formations found on Earth tell you?

Base your answers to questions 48 through 51 on the map of Long Island, New York. AB, CD, EF, and GH are reference lines on the map.

GLACIERS CHAPTER 5 HONORS EARTH SCIENCE. What is a glacier? a thick mass of moving ice

Aim: What are Glaciers? I. Glacier – found at high altitudes and high latitudes. These are locations where more snow falls during the winter than melts.

GLACIERS What is a glacier? Large volume of ice on land Doesn’t melt in the summer Ice moves and flows with the pull of gravity What does it take? Very.

Glaciers and Erosion Glacier = Large moving mass of ice and snowmovingice Alpine vs. Continental Glaciers.

GLACIERS AND GLACIATION. GLACIER A body of ice Formed on land Recrystallization of snow=> Firn => Ice Evidence of movement Alpine (valley) glaciation.

Glaciers We wouldn’t be here without them.. A Glacier is an accumulation of snow that is large enough to survive the summer melt. These large ice masses.

Glacial Erosion and Deposition. Erosion Glaciers have the capacity to carry huge rocks and piles of debris over large distances They grind out parallel.

Glaciers. “ RIVERS OF ICE ” Mass movement of frozen ice on land Mass movement of frozen ice on land Form at high elevations or high altitude Form at high.

D. Evan Stribling  a larger mass of compacted snow and ice that moves under the force of its own gravity (weight)  They erode in some places deposit.

Drumlin Streamlined hills of glacial till – drumlins indicate the direction of glacial movement.

GLACIERS A LARGE MASS OF ICE ON LAND THAT FLOWS UNDER THE PRESSURE OF ITS OWN WEIGHT – DOWNHILL OR OUTWARD DUE TO GRAVITY.

Glaciers & erosion Glaciers can leave behind large boulders known as erratic. Glaciers can move lots of sediments that can carve striations or grooves.
