The answer is B.
During plate tectonics, cracks may occur in the earth crust that causes magma to rise up from the mantle. The cracks may also cause cracks to form on the crust that makes outlet channels for the magma in magma chambers. These result in volcanic eruptions on the surface of the earth that form volcanic features such as mountains.
The Great salt lake is salty due to a high rate or water evaporation in the desert climate
Answer:
tornadoes are formed by mixing cold and hot air together.
Explanation:
Because hot air rises, when hot air from the west, clashes with cold from the east (or visa versa) the hot air rises above the cold air and causes drag on the inside of the cold air, which makes the inside of the cold air travel at a slower rate than the outside of the cold air, which in turn makes the cold air turn in on itself.
because the cold air turns in on itself, any warmer air underneath rises above the swirl of cold air forcing it to sink to earths level. "friction" or "resistance" between the swirl of cold air and the earth's surface creates more energy that is absorbed by the cold air molecules in the swirl of air, allowing the particles to move quicker and quicker in the direction they are travelling in (a bend or circle), creating a tornado.
