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.

The largest desert on earth is the Sahara Desert in Northern Africa. The Sahara is 9,400,000 km2.
Compared to the surrounding material, mantle plumes rise towards the Earth's surface from the core-mantle boundary because they are hotter and less dense (3) than the surrounding material. A mantle plume is a large column of hot rock that rises through the earth's mantle. This plume is hot enough to cause the rocks in the lower lithosphere to melt. When the plume reaches the bottom of the lithosphere, it spreads out forming a mushroom shape cap. The lithosphere is then pushed up and stretched out. This forms magma chambers which feed the surrounding surface volcanos.

When not advocating publicly for a global human rights organization, James teaches at the Outdoor Nursery School in Chevy Chase, Md. A strong proponent of education, she was recently featured on NBC Nightly News for collecting more than 600,000 pennies for education for girls.

How do you teach your preschoolers about Jamaica, your native country?
Jamaica is a jewel and very dear to my heart. I share this with my class by having Jamaica Week every year. I transform the classroom with decorations—the Jamaican flag and pictures of our musicians and athletes. They learn songs, games, and our language—the local dialect is the patois. They also taste Jamaican food, including some of my favorites: patties, stew chicken, fruit cake, plantains, rice and peas, and tamarind balls. I teach them how make their own toys, so they gain perspective on the lives of less privileged children. They make trucks, cars, balls, and windmills. This is one crafty project they love.
