What forms the elevated part of the earths crust?
continental crust
Which is not one of the eight most common elements in Earths continental?
Carbon
What provides the heat that drives the formation of igneous and metamorphic rocks?
Earths hot interior
When rock layers bend due to stress in the earths crust as in example of two continental plates converging what is the answer folding or rifting?
The answer is folding. When two continental plates converge, the stress can cause the rock layers to buckle and fold, creating mountain ranges or anticlines due to compression forces. Rifts, on the other hand, occur when plates separate or diverge, leading to the formation of valleys or grabens.
What do scientists believe that is happening to the segments of earths crust?
it has been washed into the oceans as the continental crust has eroded.
What is the relationship between society and the technologies of using earths resources?
the relationship is technologies trikes
Key events for the precambrian which makes up about 85 percent of the earths history are?
Cooling and formation of continental plates, primitive photosynthesis, free oxygen, primordial life forms, and formation of the Earth with widespread volcanic activity and meteorite bombardment.
What shows the relationship between distances on the map and the corresponding distance on the earths surface?
A map scale.
What is the general composition of earths continental crust?

What forms the elevated part of the earths crust?
continental crust
What is the average thickness of Earth's crust?
The Earths Crust can be divided between Oceanic Crust and Continental Crust. Oceanic and Continental Crust are quiet different. The thickness of oceanic crust is between 5km and 10km. It is made of mainly basalt, grabbo and diabise. The thickness of continental crust is between 30km and 50km. It is made up of lighter rocks such as granite.
What is the relationship between the density of the earths materials and depth below the surface of the earth?
As the depth increases, the density increases also.
The earths crust is made of rock sections called?
Continental plates.

Carbon

Oceanic
What is not one of the eight common elements in earths continental crust?
Carbon
