<span><em>Weathering is the gradual breakdown of rocks when they are exposed to the air. Weathering affects surface rocks the most, but water trickling into the ground can weather rocks 200 m down. The more extreme the climate, the faster weathering takes place, whether the climate is very cold or very hot. In tropical Africa the basal weathering front (the lowest limit of weathering underground) is often 60 m down. Weathering works chemically (through chemicals in rainwater), mechanically (through temperature changes) and organically (through plants and animals). Chemical weathering is when gases dissolve in rain o form weak acids that corrode rocks such as limestone. Weathering is the breaking up of rocks by agents such as water, ice, chemicals and changing temperature. The main form of mechanical weathering is frost shattering — when water expands as it freezes in cracks in the rocks and so shatters the rock. Thermoclastis is when desert rocks crack as they get hot and expand in the day, then cool and contract at night. Exfoliation is when rocks crack in layers as a weight of rock or ice above them is removed. At 22°C, ice can exert a pressure of 3000 kg on an area of rock the size of a postage stamp. The desert heat means that both the chemical and t he mechanical weathering of the rocks is intense. Hope this helped

In the atmosphere ( I hope this is right, I looked it up online )
Having climates that are good for agriculture, sophisticated infrastructure systems, the most arable land available, a variety of produce, and suitable amounts of rainfall and climate stability over a large portion of arable land. Finally, the US has high production due to advanced agricultural practices, including mechanization, fertilizers, and bioengineering.
D. North and South piglets.
Explanation: The absolute location does not change, such as the position of a place or the longitude and latitude of a place. The relative location changes depending on the person who informs of the location. On the map of fiction, the element that suggests the relative location is to the North and the South of the piglets. Directions such as north, south, east, and west of great help to explain that when a place is in relation to another.
