A. The plants will break the rock. B. The plants will make the rock hard. C. The plants will make the rock rough. D. The plants will make the rock smooth.
2.Which of the following occurs when carbon dioxide from the air or soil sometimes combines with water?
A. Carbonation B. Erosion C. Hydrolysis D. Oxidation
3. The following tends to cause physical or mechanical weathering. Which one is NOT?
A. Dead plants that produces acids B. Animal that burrows in the ground C. Root of plants growing into the cracks in the rocks D. Water that seeps into the pores and cracks of rocks
4. This type of weathering happens when the rock changes its composition.
A. Weathering B. Soil Formation C. Chemical weathering D. Mechanical weathering
5.Which of the following is the product of continuous breaking of rocks?
A. Erosion B. Soil formation C. Typhoon D. Weathering
6. The following human activities causes weathering, EXCEPT
A. Mining B. Quarrying of rocks C. Boating and fishing D. Building roads and tunnels
7.It is the breaking down of rocks into smaller particles
A. Erosion B. Formation C. Rock elements D.Weathering
8.Why is weathering useful to plants and animals?
A. Because of formation of soil B. Because of formation of rocks C. Because of the formation of fossils D. Because of the formation of landscape
9. How does temperature break the rocks apart?
A. By cooling and heating, the rock becomes hard. B. By cooling and heating, the rocks become smooth. C.By cooling and heating, the rocks become colorful. D. By cooling and heating, the structure of the rocks weakens.
10.It is the breaking of rocks physically. A. Chemical weathering B. Mechanical weathering C. Soil Formation D. Weathering
NON-SENSE = REPORT Accurate / Correct = Brainliest.
6.A and B. Acidic water can cause chemical weathering while in boating and fishing, there's not really a direct connection between the two, unless it's illegal fishing that uses explosives that could both weather minerals under water and destroy underwater life.
7.C
8.D
9.Temperature changes can also contribute to mechanical weathering in a process called thermal stress. Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens. Over time, it crumbles.
