Answer:
Air pressure is influenced by the differences between hotter and cooler pockets of air, or fronts.
Explanation:
When atmospheric pressure is low, air is pushed down toward the surface, meaning rain and moisture don't accumulate. This often also leads to high humidity near the surface of the Earth, where people experience weather.
Answer:
1. Another word for chemical weathering is b. disintegration
Chemical weathering is a process by which the rocks are broken down into parts and sediments by the action of a chemical agent such as alkali or acid. The disintegration can be a natural process by which a solid body is broken down into parts or subparts.
2. d. moving water is not an agent of chemical weathering agent.
The chemical weathering can be caused by the agents like lichens which secretes acid on the rock surface and causes it's disintegration, acid rain and salt water are chemical agents that can cause the disintegration of the rock but moving water will have little influence on the hard rock surface.
3. c. chemical weathering is a process which turns rocks and minerals into new substances. The chemical weathering process brings change in the chemical composition of the rocks due to the action of the weathering agents hence, on disintegration of rocks new substances are formed.
