I believe that the answer is Urea.
Answer:
Conditions at the base of a glacier increase glacial flow velocity -
Steeper slope
Smooth rock / glacier contact
Colder basal water temperature.
Explanation:
Steeper slope and smooth rock/glacier contact will increase glacial flow velocity because higher the steepness higher the velocity and smoothness will apply less friction.
Due to decrease in ice thickness the load at the bottom of the glacier will decrease, and we know that the glacier flows under the load of itself, so lesser the load lesser the velocity.
Colder basal water temperature will generate less amount of melt as compared to warmer basal water temperature, so in colder condition, glacial flow velocity will not be increased.
The main mechanism through which the layering happened is gravity: it pulled the heavier, denser material to the center, leaving the less dense material on the surface.
The material that was on the outside cooled quicker, but this was the result, not the cause.
The answer is
<span>2) Gravity caused more-dense material to move toward the center of each planet.</span>
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.
