Answer:
The permanent base level of a sea is the lowest level to which a sea can erode a landmass. The sea is a overflowing water 24/7 the tides also play a role
If not for the Earth's rotation, global winds would blow in straight north-south lines. ... The Coriolis effect influences wind direction around the world in this way: in the Northern Hemisphere it curves winds to the right; in the Southern Hemisphere it curves them left. The exception is with low pressure systems.
They form only above snowlines at higher altitudes where so cold and dry snow doesn't melt and accumulates.
Answer:
The method that scientists use to discern this information is similar to medical CT scans that bounce X-rays through the human body to make three-dimensional pictures of internal tissue. In an analogous manner, a method called seismic tomography uses hundreds to thousands of earthquakes recorded by dozens of stations to measure the speed of seismic waves through the Earth--data that allow geophysicists to make three-dimensional pictures of structures beneath the surface. Scientists compare these seismic velocities and infer the composition by comparing them with average, thermally undisturbed values.
