Step-by-step explanation:
20. If there is more friction, rivers flow slower and there is more erosion. Friction between the water and the riverbed slows down the flow of water, which can cause sediment to be deposited and lead to erosion. In fact, a lack of friction can cause fast-moving water to erode the riverbed and banks more quickly.
21. Glaciers are masses of ice that move slowly over the land due to gravity. They form when snow accumulates over time, compresses, and recrystallizes into ice. Glaciers can be found in many parts of the world, from polar regions to high mountains, and they play an important role in shaping the landscape and influencing the climate.
22. Valley glaciers are also known as alpine glaciers, and they form in mountain valleys or on the sides of mountains. They flow downhill between two mountain peaks and can carve out U-shaped valleys as they move. Valley glaciers are typically smaller than continental glaciers, which cover entire land masses, and they are found in many mountainous regions around the world.
23. Glaciers do move with the force of gravity. The weight of the ice causes it to flow downhill, following the path of least resistance.

25. Materials are picked up by a glacier in a process called "plucking" or "entrainment". As a glacier moves, it can pick up rocks, soil, and other debris, incorporating them into the ice. This material can then be transported and deposited elsewhere as the glacier melts.
26. Till, moraine, and drumlin are all features that are associated with glaciation. Till refers to the unsorted mixture of sediment that is left behind by a retreating glacier. Moraine is a ridge or mound of sediment that is also left behind by a glacier, and it can form at the edge of the glacier or in the middle of it. Drumlin is a type of hill that is formed by the movement of a glacier and is usually elongated in the direction of ice flow. Till can contribute to the formation of moraines and drumlins, which are both composed of sediment that was picked up and transported by a glacier.
