The two main types of erosion are:
Q. What evidence would show that an area was once covered by a glacier?
The most apparent evidence is of course the glacial drift itself. Glacial drift refers to the rock material ground up and transported by a glacier and deposited by or from the ice (till) or in water derived from the melting of ice (outwash or lake sediment).

Q. How do glaciers cause deposition quizlet?
How do glaciers cause erosion and deposition? Two process by which glaciers erode the land are plucking and abrasion. When a glacier melts, it deposits the sediment it eroded from the land, creating various landforms.
Q. Where a river flows from an area of harder rock to an area of softer rock the softer rock may wear away eventually forming a drop called a n?
Where a river flows from an area of harder rock to an area of softer rock, the softer rock may wear away, eventually forming a drop called a waterfall. A waterfall is a body of water in which water flows over the edge of a cliff into a plunge pool under it.
Q. What process causes glacial erosion?
The two main processes that lead to glacial erosion are plucking and abrasion. Plucking is the process by which a glacier picks off rocks as it blocks over the land. The rock fragments freeze to the bottom of the glacier, gouging and scratching the bedrock as the glacier advances in the process of abrasion.
- Abrasion – as the glacier moves downhill, rocks that have been frozen into the base and sides of the glacier scrape the rock beneath.
- Plucking – rocks become frozen into the bottom and sides of the glacier.
Q. What are two main types of glaciers?
There are two main types of glaciers: continental glaciers and alpine glaciers.
Q. What are 3 physical features that have been formed by glaciers?
Glacier Landforms
- U-Shaped Valleys, Fjords, and Hanging Valleys. Glaciers carve a set of distinctive, steep-walled, flat-bottomed valleys.
- Cirques.
- Nunataks, Arêtes, and Horns.
- Lateral and Medial Moraines.
- Terminal and Recessional Moraines.
- Glacial Till and Glacial Flour.
- Glacial Erratics.
- Glacial Striations.
Q. What qualifies as a glacier?
A glacier is a large, perennial accumulation of crystalline ice, snow, rock, sediment, and often liquid water that originates on land and moves down slope under the influence of its own weight and gravity.
Q. What is the main difference between a snowfield and a glacier?
Snowfields are like young glaciers. If they grow large enough, the snow will pack together into ice and begin to flow like a glacier. A glacier is a large amount of ice that sits on the land.
Q. Which amongst the following is the largest glacier?
The world’s largest glacier is the Lambert glacier in Antarctica , according to the United States Geological Survey. The glacier is more than 60 miles (96 km) wide at its widest point, about 270 miles (435) long, and has been measured to be 8,200 feet (2,500 meters) deep at its center.
Q. Which continent has most rain?
South America is the wettest and has the largest river flow and evaporation (Table 1)….Water balance of the continents.
| region | North America |
|---|---|
| precipitation: mm/a | 800 |
| discharge mm/a | 330 |
| ratio: percent | 41 |
| evaporation mm/a | 470 |
Q. What 2 continents have the most similar climates?
Explanation: These two continents are familiar in many ways. Apart from the different culture, both are expanding, and developing regions. South America and Africa experience heavy rainfall and a high degree of sunshine, that led to the formation of some of the forests, like Amazon and Congo Forest.
