Why do seismic waves speed up beneath the surface of continents?
Because earths crust is denser than the mantle
How does isostasy impact the surface of the earth?
Isostacy refers to an equilibrium level maintained by the earths crust on top of the mantle. The theory holds that the weight of the earths crust will displace a certain amount of the underlying mantle, and that an equilibrium is reached whereby the mass of the displaced crust and the mass of the displaced mantle are equal, thus holding that part of the crust at a certain height.
Why does water float on Earth's surface?
Oceanic crust is denser than continental crust, it floats lower in earths mantle.
The balance between the weight of a continent and the buoyant force of mantle is?
isostasy
The balance between the weight of a continent and the buoyant force of mantle is called?
isostasy
What is the concept that rocks of the crust and upper mantle are floating in gravitational balance?
isostasy
The balance between the weight of a continent and the buoyant force of the mantle is called?
isostasy
Why is the lower mantle denser the the upper mantle?
The lower mantle is under greater pressure than the upper mantle, compressing the rock into a denser form.
Concept that rocks of the crust and upper mantle are floating in gravitatioal balance?
It is the concept of isostasy.
What are facts about earths upper mantle?
Temperature is about 2000 to 3000 degrees celsius maybe less.The mantle is hot but not the hottest layer.It is is the second layer of the Earth. The mantle is the thickest layer of the earth, it is the layer of the earth beneath the crust.Upper mantle and Lower mantle are the two parts of the mantle, The lower mantle is deeper and denser than the upper mantle .
The balance between the downward push of continents and the upward push of the mantle is called isostasy?
TRUE
How many layers in earths mantle?
there are 7 layers in earths mantle.
