How do Glaciers change the earth’s surface? BY MRS. J
Overview GlaciersWeathering and Erosion Effects Deposition Effects
Glaciers Compressed snow layers Cold year-round: advance, retreat Moved by gravity and pick up sediment Ice mass moves slowly (1-2 in./day) Changed land surface over many years
Weathering Effects Weathering Rocks broken into smaller pieces Ice crushes rocks into sediment Rocks grind other rocks Effects Glacial Striations = long scratches Glacial Polish = flatten and shine rocks
Erosion Effects Erosion Pluck rocks and pick up sediment Carry sediment downhill Effects Horns = ice carves out sides of peak Missing sediment = empty space U-Shaped valleys = half-pipe shape
Deposition Effects Deposition Relocates sediment and rocks Effects Moraines = piles of rocks or sediment Kettles: ice fills area and melts Erratic: material different from things around it

Ch.9 Erosion and Deposition. Section 4: Glaciers How Glaciers Form and Move – Glacier is defined as any mass of ice that moves slowly over land – There.
AIM: How do Glaciers change the landscape? Do Now: The material seen below was left behind by a retreating glacier. Describe the sediments seen in the.
Chapter 7.3 Glaciers. Glacier Any large mass of ice that moves slowly over land. Two kinds: – Continental Glaciers – Valley Glaciers.
Glaciers How are Glaciers and Long Island related?
Features of erosion and deposition associated with glaciated landscapes.
Erosion: Deposition: AIM: Erosional and Depositional systems Do Now: In your notebooks… 1) Define the two terms below in your own words. 2) Explain how.
Glaciers Chapter 3 Section 4 Pages Objective: Describe the causes and types of glaciers, how they impact land features, and analyze their role.
SECTION 4 GLACIERS. KEY TERMS GLACIER Any large mass of ice that moves slowly over land There are 2 kinds of glaciers continental and valley.
As glaciers travel over land, glacial ice can erode the underlying bedrock. This erosion can happen by: Plucking Abrasion.
Erosion The movement of sediments by wind, water, ice, or gravity.
Glaciers and Erosion Glacier = Large moving mass of ice and snowmovingice Alpine vs. Continental Glaciers.
Chapter 8 Erosional Forces Section 8-2 Glaciers Note Guide.
Erosion and Deposition by Glaciers 1. What are Glaciers? Glaciers are: any large mass of ice that moves slowly over land 2.
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 Chapter 3 Section 4 Standards S 6.2a Surface water flow, glaciers, wind, and ocean waves have all been and continue to be active throughout.
Chapter 3 Erosion and Deposition Section 4 Glaciers.
CHAPTER 7 UNIT 2. The material moved by erosion is called ___________________.
Chapter 7: Erosion and Deposition 7.1: Forces wear down and build up Earth’s surface 7.2: Moving water shapes land 7.3: Waves and wind shape land 7.4:
External Forces that Shape the Earth. Erosion Occurs when weathered material is moved by the action of wind, water, ice, or gravity There are several.
What is a Glacier? = An accumulation of compacted snow & ice that moves slowly under the force of gravity 2 types of glaciers: 1.Valley glacier = wedge-shaped.
Glaciers We wouldn’t be here without them.. A Glacier is an accumulation of snow that is large enough to survive the summer melt. What are glaciers?
Erosion and Weathering. What is erosion? (geology) the mechanical process of wearing or grinding something down (as by particles washing over it) The.
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.
Glacial Erosion and Deposition. Erosion Glaciers have the capacity to carry huge rocks and piles of debris over large distances They grind out parallel.
Agenda Check In Review notes Glaciers WATER Who’d’a Thunk: Karaoke means “empty orchestra” in Japanese.
Chapter 8, Section 2. What is a glacier? Large mass of snow and ice that moves on land under its own weight.
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.
Ch 15: p Enormous masses of moving ice created by the accumulation and compaction of snow. Powerful agents of erosion ~ have carved some.
Erosion by Glaciers. Index Types of Glaciers Features Deposition Formation of Long Island.
10.4. Erosion Water, in either gas, liquid, or solid form can change the surface of the earth, it can even carve rock! Erosion is the transportation.
Glaciers Chapter 3 Section 4. Standards S 6.2a Surface water flow, glaciers, wind, and ocean waves have all been and continue to be active throughout.
1. _____type of rocks that form in oceans, rivers, and lakes (sediemntary rock) 2. _____type of igeous rock that cools on Earth’s surface (igneous)

‘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.
How do Glaciers Effect the Land? By erosion & deposition.
What things change the Earth’s surface slowly?. Slow Changes to the Earth’s Surface Process is a synonym for change. Slow Process- A change that occurs.
GlacierNotes. Cryosphere – sea ice – ice shelves – icebergs – ice sheets – glaciers – lake ice – river ice – snow – permafrost All of the frozen areas.
Erosion by Glaciers. A glacier is Any large mass of ice that moves slowly over land Think of it as a moving river of ice and snow.
