Glaciers shape the landscape by eroding and depositing rocks and soil. They carve valleys into U-shapes, create fjords, and leave behind features like moraines and drumlins.
MCQs
1. Which of the following is a way that glaciers can change the landscape?
A) Building mountains
B) Melting into rivers
C) Carving valleys
D) Growing plants
Answer: C) Carving valleys
Explanation: As glaciers move, they erode the land beneath them, carving out valleys and shaping the landscape.
2. How do glaciers contribute to the formation of lakes?
A) By heating up the ground
B) By creating dams with ice
C) By leaving behind depressions that fill with water
D) By pumping water from underground
Answer: C) By leaving behind depressions that fill with water
Explanation: When glaciers retreat, they often leave behind depressions in the land. These depressions can fill with water, forming lakes.
3. What are moraines?
A) Types of mountain goats
B) Hot springs found near glaciers
C) Piles of rocks and debris left by glaciers
D) Underground caves in glaciers
Answer: C) Piles of rocks and debris left by glaciers
Explanation: Moraines are accumulations of dirt and rocks that have been pushed along and deposited by a glacier, often marking the glacier’s former extent.
4. What term describes the process of glaciers breaking off into the ocean?
A) Sublimation
B) Calving
C) Condensation
D) Erosion
Answer: B) Calving
Explanation: Calving is the process which glaciers lose chunks of ice at their edges, which break off and fall into the ocean, forming icebergs.
Fill in The Blanks
Choose from These Words: valleys, lakes, moraines, movement.
1. Glaciers can carve out deep ________ in the landscape.
Answer: valleys
2. When glaciers melt, they can create ________ and rivers.
Answer: lakes
3. Deposits of rocks and sediment left behind by glaciers are called ________.
Answer: moraines
4. Glaciers can change the shape of the land through their ________.
Answer: movement
True / False
1. Glaciers are made of flowing water (True / False)
False: Glaciers are made of ice, not water. They are formed from layers of snow that have compacted over time.
2. Glaciers can carve out valleys (True / False)
True: Glaciers can shape the land by carving out valleys as they move and erode the surrounding rock and soil.
3. Glaciers have no impact on the landscape (True / False)
False: Glaciers have a significant impact on the landscape by shaping and sculpting the land as they move and erode the land beneath them.
4. Glaciers are stationary and do not move (True / False)
False: Glaciers are constantly moving, albeit very slowly, due to the force of gravity pulling them downhill.
