What is earth hard surface is formed of?
It is the surface we live on and is known as the Earth's Crust.
What in the world is the lithosphere?
The lithosphere is the solid, rocky layer covering the entire surface of the planet, composed of the crust and the hard uppermost mantle, and reacts to stresses as a brittle solid. The lithosphere ranges in thickness from 50 - 200 km and is fragmented into tectonic plates with boundaries where plates collide, diverge, or grind past each other.Lithosphere is the solid part of the Earth.Like land,and crops.The land part of the earth on the crust

What is the definition of the crust of the earth?
The Earth's outermost layer of hard brittle rock is called the crust. The crust is typically about 23 miles thick beneath continents, and about 6.5 miles thick beneath oceans. The crust is relatively light and brittle compared to other Earth layers. Most earthquakes occur within the crust.
Crude oil is often found in the Earths crust why is this a problem?
billions of gallons of oil and tons of coal has been extracted from the earths crust which is obviously leaving an emptyness behind, i find it hard it hard to believe that this space remains empty without any collapse in the crust to fill the empty space. if there was a collapse in the earths crust then it would surely be felt as an earthquake or maybe even a tsunami.Earth is only a few kilometers thickness but crude oil pockets could lie anywhere, even under the sea.The crust has to be bored and plugged up for extraction which causes spillage and harms bio life to upset the ecology.
