1.
- Soil: crop rotation, fewer concrete surfaces, plant trees to secure topsoil
2. Advantages
- coal: easy to burn, inexpensive
- Oil: easily available, used in a variety of industries
- Natural gas: Easy to store, cheap
3. Disadvantages:
- Coal: Produces large amount of CO2, fast depleting as we consume so much of it
- Oil: releases greenhouse gases, water pollution
- Natural gas: highly flammable, release greenhouse gases
The first thing to say is that there are two geographical features with the same name: the Rocky Mountain System and the Rocky Mountains (s.s.) that are part of it.The complete orographic system is something like a very varied sample of geological and tectonic processes.The system extends for more than 2982 miles, from Canada to the southern United States, (state of New Mexico). Its transverse extension varies between 68 and 300 miles, with the eastern edge being very close to Denver, and constituting a prominent feature within the central plains of the continent.The far west is not far from Salt Lake City, Utah, and is separated from the Sierra Nevada, Cascade, and Coastal chains-farther west-by the Great Basin and the Columbia River Plateau.The Rocky Mountains end before entering Alaska, not the System that contains them, which is also known to include the highest peaks in North America. In the United States, the highest height is recorded at Mount Elbert in Colorado, showing 4,401 m.s.n.m.Also in the Rocky Mountains is the watershed of the continent, which obviously separates the basins that drain towards the Pacific from those that drain towards the Atlantic.
The correct answer is - The rock cycle is driven by the movement of the tectonic plates.
The rock cycle can simply be taken as the formation, evolution and existence, and destruction of the rocks. This cycle is a result of the movement of the tectonic plates. Most of the new rocks form on the divergent boundaries, where the magma creates new crust, the ones that are between the boundaries are the rocks that are in their evolution faze, and the rocks that are finding into a situation to be at the convergent boundaries are getting destroyed as they get into the mantle layer.

The primary cause of change in regional metamorphism is pressure. Usually rocks subjected to high pressures at considerable depth within the earth's crust will exhibit regional metamorphism like the widespread phyllites, schists, gneisses and migmatites of the Canadian Precambrian Shield for example. A phyllite is the next higher metamorphic stage than a slate, a schist is a further stage and gneiss and migmatites are of the highest grade of regional metamorphism. On the other hand, contact metamorphism usually depends more on the effect of heat from an igneous intrusion say converting a limestone to a marble (more coarse grained than limestone usually).
