Glaciers and Long IslandHow are Glaciers and Long Island related?
Glaciers Snowfall exceeds melting. High altitudes and polar regions.Gravity moves mass downhill. Firn = very dense snow layer.
Continental Glaciers Ice sheets that cover continents.Kilometers thick. Only 2 exist: - Greenland and Antarctica
Valley Glaciers Begins in a cirque = bowl-shaped basin at mountaintop.Crevasses = cracks in the glacier.
Erosion U-shaped Valleys Cirques, Aretes and Horns.Hanging Valleys - from tributary
Erosion Striations = parallel scratches on bedrock... from rocks on bottom of glacier Polish = fine material rubs rock smooth.
Deposition Moraines - Unsorted pile of debris = tillErratics = large isolated boulders. Drumlins = long, low mounds of till with teardrop shape. Outwash Plain (sorted) = sediments that are “washed out” in front of glacier.

Lakes Kettle Formation:
Glacial Lake Forms when ice dams a stream.
Ice Age Glacier Limit
GLACIERS AND GLACIATION. GLACIER A body of ice Formed on land Recrystallization of snow=> Firn => Ice Evidence of movement Alpine (valley) glaciation.
Glacier: Any large mass of ice that moves slowly over land.
Mysterious rock formations…….. What could have caused these formations? GLACIERS!!!!!
Glaciers & Glaciation. Glaciers Glacier: a large, long-lasting mass of ice, formed on land that moves under the influence of gravity and its own weightGlacier:
Glaciers. Glacier - a thick ice mass that originates on land from the accumulation, compaction, and recrystallization of snow. Formation of glacial ice.
Erosion and Deposition by Glaciers Created By: Belinda Schmahl.
Glaciers Glaciers formed much of the landscape that exists presently in the northern United States and elsewhere in the world. Glaciers Today, scientists.
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.
Geologic Features of Glaciation. Horn Mountain peak formed by glacial erosion.
Glacial Landscapes Glacier = large moving mass of ice. Glacier = large moving mass of ice. Glaciers erode, transport and deposit massive amount of sediment.
Glaciers Section 9.4. Glaciers are any large mass of ice that moves over land Continental Glaciers - cover much of a continent or large island (10% of.
Glaciers and Erosion Glacier = Large moving mass of ice and snowmovingice Alpine vs. Continental Glaciers.
Glacial Erosion and Deposition. Erosion Glaciers have the capacity to carry huge rocks and piles of debris over large distances They grind out parallel.
Study Guide Chapter What is a glacier? 2.Distinguish between alpine and continental glaciation. 3.Explain how a glacier moves. Explain how a crevass.
Form in high mountains where snow accumulates to sufficient depths so that it is compressed, compacted and recrystallized. For this reason glacial.
Ch 15: p Enormous masses of moving ice created by the accumulation and compaction of snow. Powerful agents of erosion ~ have carved some.
Glacial arete and col. drumlin valley glacier and medial moraines.
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.
‘S‘S. VOCABULARY GLACIER - LARGE MOVING MASS OF ICE THAT FORMS NEAR EARTH’S POLES AND IN MOUNTAINOUS REGIONS AT HIGH ELEVATIONS. GLACIER - LARGE MOVING.
Glaciers once covered most of the Earth –in total there have been up to 22 times when glaciers covered large areas of the Earth… including Alberta the.
Glaciers. A GLACIER forms when yearly snowfall in a region far exceeds the amount of snow and ice that melts during the summer months. Most of the world's.
GLACIERS CHAPTER 5 HONORS EARTH SCIENCE. What is a glacier? a thick mass of moving ice
Glaciers and Glacial Landforms
What is a Glacier? REVIEW = An accumulation of compacted snow & ice
Glaciers and Erosion Chapter 7 Section 1.
An introduction to where, how, and why glaciers form
Guided Notes For Glaciers Section 8.3. Glaciers shape the landscape by eroding, transporting, and depositing huge volumes of rock and sediment.
CHAPTER 5 HONORS EARTH SCIENCE
An Introduction to a Powerful Force That Has Shaped the Earth.
Chapter 5: Section 2 Surface Processes and Landscapes
Erosion: Deposition: AIM: Erosional and Depositional systems
The movement of sediments by wind, water, ice, or gravity.
CHAPTER 7.1B GLACIERS. LANDFORMS CREATED BY GLACIAL EROSION Glaciers produce things like glacial troughs, hanging valleys, cirques, aretes, and horns.
As glaciers travel over land, glacial ice can erode the underlying bedrock. This erosion can happen by: Plucking Abrasion.
Erosion by Glaciers. Index Types of Glaciers Features Deposition Formation of Long Island.
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.
Chapter 15-1 Glaciers Pages
Geology of Great Lakes How the lakes formed.
Formation Snow accumulation More winter snowfall than summer melt Glacier formation is similar to sedimentary rock formation.
Chapter 8 Erosional Forces Section 8-2 Glaciers Note Guide.
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.

Glaciers. Geologists define a glacier as any large mass of ice that moves slowly over land. There are two types of glaciers: Continental glaciers Valley.
