The rate of chemical weathering is controlled by such things as the temperature, the amount of rainfall and the surface area of the minerals which constitute the rocks. Rocks with a finer grain size have more surface area than coarse-grained rocks so are more susceptible to chemical weathering, like a volcanic rock compared to a granite, say. With higher temperatures and greater rainfall, chemical reactions in the rocks are facilitated and this is why, for example argillic (clay alteration) alteration is so well developed in the tropics (in El Salvador for example and also why the lateritic soils develop in countries like Indonesia and can contain economic amounts of nickel for exampl) . A factor which controls the rate of physical weathering could be the development of glaciers which transport rocks in their bed, which shapes these boulders and also scores the rocky surfaces these scrape over as the glacier moves. Alternate freezing and thawing in the spring time in the northern hemisphere can speed up the breakdown of the rock by cracking it or opening up pre-existing joints and faults.
and also the surface area of the minerals being attacked.

Answer:
They provide us with accurate data that is needed to make adjustment on earth's surface.
Explanation:
- The use of techniques like the Global positioning system, Geographic information system, and remote sensing is a tool that provides us with geospatial information and help us understand the laws of nature.
- These all act as sensors and provides us information directly from the space with coordination to sun-synchronous and geostationary satellites.
- The use of technology like the lidar and radar also helps in understanding the global warming and deforestation patterns around the world.
he was in there with his two brothers
Explanation:
if you look at the text you can see who was in there with him and then use a geography site to extend your answer
