What are the two types of crust that makes up the continents and ocean?
The two types of crust that make up the continents and ocean are the continental crust and the oceanic crust.
What is the portion of the ocean floor that is made up of oceanic crust?
the deep ocean basin
What is two differences between the continental crust and oceanic crust?
The oceanic plate is thin, dense, and makes up the ocean floor. The continental plate is less-dense, thick, and make up the continents.
What type of rock makes up the ocean floor?
Primarily lime stone.
Is basalt common?
Basalts are as common as the formation of the Ocean floor. Basaltic rocks are ferromagnessian rocks and intrusive igneous rocks. This implies they are formed within the Earth's crust, and they make up the ocean floor. They are dark and dense rocks and occurs in large scale as M.O.R.B. (Mid-oceanic Ridge Basalt).

What makes up the continents and the ocean floor?
The continental and oceanic plates are primarily igneous rock. The continental crust is granitic and the oceanic crust is basaltic.
What is the compition for the crust?
Crust is made up of mainly granite, a felsic rock wit a lower density than basalt, what makes up the ocean's crust, thus why the continental crust rises up compared to ocean crust.
What does ocean crust mean in science?
The oceanic crust is the part of the earth's crust that is below the ocean. The rock that makes up the oceanic crust is about 200 million years old.
Iron rich volcanic rock that makes up much of the ocean floor is?
The volcanic rock that makes up most of the ocean floor is called sediment.
What evidence in rock supports the theory of seafloor spreading?
Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.
A rock that makes up much of the ocean floor?
basalt
What are four differences between the oceanic crust and the continental crust?
1. The Oceanic crust is dense while the Continental crust is relatively lighter. 2. The Oceanic crust consists of Silicon and Magnessium, while the Continental crust has Silicon and Alluminium. 3. The Oceanic crust is thin, while the Continental crust is thick. 4. The Oceanic crust makes up the ocean floor, while the Continental crust carries the continents.
