Answers
Answer:
1.Humus is dark, organic material that forms in soil when plant and animal matter decays. When plants drop leaves, twigs, and other material to the ground, it piles up. ... The thick brown or black substance that remains after most of the organic litter has decomposed is called humus.
2.Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
3.Bedrock is the hard, solid rock beneath surface materials such as soil and gravel. Bedrock can be made of most types of rock, such as granite, limestone, or like this piece of bedrock, sandstone. .
4.Thunderstorm, a violent short-lived weather disturbance that is almost always associated with lightning, thunder, dense clouds, heavy rain or hail, and strong gusty winds.
5.The wind is caused by differences in atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator.
6.The anemometer counts the number of rotations, which is used to calculate wind speed. An anemometer is an instrument that measures wind speed and wind pressure. Anemometers are important tools for meteorologists, who study weather patterns. They are also important to the work of physicists, who study the way air moves.
