The San Andreas Fault is a continental transform fault that extends roughly 1300 km in California. It forms tectonic boundary between Pacific plate and North American Plate. Its motion is right-lateral strike-slip. It is divided into three segments, and each of this segments has different characteristics and different degree of earthquake risk. The most significant segment is the southern one, which passes within about 35 miles of Los Angeles. This fault was first identified by professor Andrew Lawson from the UC Berkley in 1895.
The two minerals that are found in cement are : Silica and calcite.
<u>Explanation:</u>
Different minerals form the composition of cement but the minerals that are most commonly found in cement are calcite which is contained in the limestone.
The other mineral that is used in the production of cement is silica in the form of raw rock type used to make cement which is found in clay. So they form an important part of formation of cement.
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.
Dead zones are hypoxic (low-oxygen) areas in the world's oceans and large lakes, caused by "excessive nutrient pollution from human activities coupled with other factors that deplete the oxygen required to support most marine life in bottom and near-bottom water.
