Lithosphere literally means "rocky globe" and refers to the rough outermost layer of any rocky planet--Earth included. For that reason the crust and the coolest top part of the mantle of Earth is called the lithosphere because it is the most rigid layer of the Earth in comparison to the hotter, more viscous layers beneath it.

The Lithosphere is the solid rock layer atop the molten mantle of earth. It makes up the tectonic plates and land masses.

Why are basalt and granite important igneous rock?
As it turns out, most of the ocean floor is basalt, and most of the continents are granite.
Where is the most of the basalt found on earth?
Most Basalt is found mostly in oceanic plates of Earth.
Is basalt found under water and by volcanoes?
yes. some types of basalt is found of volcanoes.
Where is basalt located?
Basalt is generally found on and near volcanoes.
Why are the oldest parts of the earth's crust found on continents?
The older peices of the Earths crust are significantly lighter than the newer peices, (i.e. oceanic plates / basalt) forcing them to the surface.

Where was the basalt slab found?
Basalt is the result of lava flows from volcanoes. Basalt flows and or 'slabs' can be found anywhere volcanoes are. In fact, the entire islands of Hawaii are really just a huge basalt slab.
What is the bedrock that makes up the bulk of the continents?
basalt i thhink just kidding i am obliviose
How do you use the word basalt in a sentence?
The explorer found a basalt inside of a volcano.
What are two sentences that use basalt?
Basalt can be found under the earth. I would like to see real basalt in my lifetime.
