If the tectonic plates float on a layer of the earths crust what is it called?

The mantle or perhaps you are referring to the asthenosphere, the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.


Describe the asthenosphere?

Another name for the lower mantle is called the asthenosphere.


Why do crevasses form in the upper portion of a glacier but not below a depth of about 50 meters?

Crevasses form on the upper portion of the glacier because when a glacier moves over irregular terrain, the zone of fracture is subjected to tension, which forms the crevasse. The reason why it may not form below the depth of 50 feet is because plastic flow seals them off.


What are flow meters used for?

Flow meters are used to measure the linear, nonlinear, mass, or volumetric flow rate of a liquid or gas.
