What is composed of the continents and the oceans floor?
Earth's crust is composed of the continents and the ocean floor.
Does sea-floor spreading occur in oceans only?
It occurs in the oceanic crust!!!
What is the definition for earth's crust?
the outer layer of earth ; includes continents,oceans and ocean floor
Continents and the ocean floor are part of earths solid rocky surface called?
crust
The oceans crust is composed of what?
The oceanic crust composed of sima, mafic rocks and basalt. This is the top layer of the lithosphere which is found in the ocean floor.
What is the chain of mountains that extends into all of earths oceans is called?
The ocean ridge.
The floor of heavier rock under the oceans is composed of?
The floor of heavier rock under the oceans is primarily composed of basalt. Basalt forms from volcanic activity and makes up the majority of the oceanic crust.
What scientist studies the earths crust the mantle the crust continents and the ocean floor?
A geologist studies the Earth's crust, mantle, continents, and ocean floor. They investigate the composition, structure, and processes of these layers to understand Earth's history and dynamics. Geologists also examine natural resources and environmental implications related to these components.
How wide is the crust?
The Earth's crust can vary in thickness, but on average it is about 5-70 kilometers (3-44 miles) thick. However, it can be much thicker under mountain ranges and thinner under the ocean floor.
What layer of the earth's interior contains the highest mountains and the deepest oceans?
The Earth's lithosphere, which includes the crust and the uppermost part of the mantle, contains both the highest mountains (on the crust) and the deepest oceans (in the oceanic crust). The lithosphere is broken into tectonic plates that float on the semi-fluid asthenosphere below.
What is the measurement of the earth's crust?
The Earths crust is about 6miles thick and it covers the entire earth even at the bottom of oceans. The crust is only the beginning of the Earth and underneath is the mantle, outer layer and inner core.
Is it true that tectonic plates made up of land and ocean floor?
Yes, there are two types of crust on the Earth, oceanic and continental. The crust under the oceans is, of course, oceanic crust which has more mass than continental crust. Each type is formed from plates of different size and shape.
