Steep slopes b Limestone formation of at least 80% calcium carbonate c. Complex pattern of joints d. Vegetation cover Sinkholes and underground caverns are characteristic of a. Convergent plate boundaries b. Karst landscapes C. Salt-crystal growth d. Calderas 35) Processes relating to streams are termed a. Fluvial b. Geomorphological c. Metamorphic d. Volcanic 36) As the discharge of a stream increases, which of the following happens? a. the rate of flow decreases b. channel width increases but channel depth decreases c. width, depth, and velocity all increase d. stream channels narrow, become shallower, and lose velocity 37) As the velocity of a stream increases, its ability to carry sediment decreases. a. True b. False

Explanation / Answer

32. Answer: d. All of the above Explanation: Amount of vegetation affects the weathering because of the penetration of roots into the rock to break it into smaller pieces. Depending on the rock type, that is soft or hard, the weathering occurs because in soft rock like sandstone or mudstone the chemical bonds are weaker for the weathering agents to react easily. Climatic conditions like temperature and pressure changes introduces freezing and thawing which weathers rocks. 33. Answer: a. Steep slopes. Explanation: Slope should be gentle to encourage the water to float so that the limestone can be dissolved to form karst landscapes. 34. Answer: b. Karst landscapes. Explanation: Ground water that moves in the karst landscapes are forming a cave underground called sinkholes. 35. Answer: a.Fluvial Explanation: Fluvial process is the movement of sediments and deposition in the streams.
