Answer:
Frost Action in temperate regions of the world
Salt weathering in coastal and arid regions
Thermal expansion and contraction in tropical climates
Explanation:
Mechanical weathering is also known as physical weathering, and it entails the disintegration of rocks into smaller fragments.
Weathering processes generally take place slowly with time. Also, they are geography specific. One such means is frost action. In frost action, a freezing and thawing cycle catalyze rock disintegration. When water freezes, it expands 9 percent in volume. The expansion causes stress which forces rock disintegration.
Also, in some coastal and arid regions, salt crystals may grow from saline solutions on evaporation. When these salts crystallize in interstices of rocks, they produce stress and widen pores. This weathering process is very slow.
Another very effective mechanical weathering process which occurs in tropical regions of the world is thermal expansion and contraction. It's a prolonged process in which daily heating and cooling of rocks cause a rock to expand during the day and contract at night. This alternating process causes cracks to open up in a rock body.
Hello,
The distance between the sun and Earth is about <u>93 millions miles</u> or <u>150 millions kilometers</u>.
I hope it helped ^_^ ✅
Glaciers. This is because glaciers are giant frozen bodies of water. When the glaciers melted in the summer, they flowed down mountains and into the ocean.
Radio waves (similar to electromagnetic radiation) travel at the same speed of light, that is 300,000 km/second.
Jupiter being at 630,000,000 km from earth, the time needed to get the radio waves on earth = 630,000,000/300,000 = 2,100 sec or 35 minutes
