How many layers are there in the earth's crust?
The crust alone contains millions of different layers of sedimentary rock. For the layers of the Earth, some of which are rock and some of which are not, see the related link below.
What does the Earth consist of?
The Earth consists of several layers: the core (inner and outer), mantle, and crust. The core is mainly composed of iron and nickel, the mantle is mostly silicate rocks, and the crust is a thin layer of solid rock that includes both oceanic and continental crust.
How many layers is the oceanic crust?
There are 5 layers in the ocean, I learned them in Science, the layers are: 1. epiplogic 2. mesoplogic 3. bathyplogic 4. abyssaplogic 5. hadoplogic who ever told you 3.....well sorry its wrong....so there ya have it (i might spelled some wrong but these are the layers and if you disagree complain to the laws of physics NOT ME!!!)
How many tectonic plates in oceanic crust?
There are 9 major tectonic plates in the Earth\'s oceanic crust, six of which receive the names of the continents they hold.
How is the difference in density between the oceanic crust and the continental crust important?
Oceanic crust is thin, dense and composed of mainly silicon and magnessium While the Continental crust is thicker but less dense in comparism with the oceanic crust and its composed mainly of silicon and aluminium.

Volcanoes only occur in oceanic crust?
Volcanoes do not only occur in oceanic crust; they can also be found in continental crust. While many volcanic eruptions happen at mid-ocean ridges or subduction zones associated with oceanic plates, continental volcanoes can form due to rifting, hotspots, or tectonic activity in continental regions. For example, the Cascade Range in the Pacific Northwest of the U.S. features volcanoes formed on continental crust. Thus, both oceanic and continental crust can host volcanic activity.
What does the Earth consist of?

How many times thicker is the continental crust to the oceanic crust?
The continental crust is about 35 to 40 kilometers thick, while the oceanic crust averages at about 7-10 kilometers thick. This means that the continental crust is about 3.5 to 4 times the thickness of the oceanic crust.
Why are continental plates less dense than oceanic plates kids answer?
Continental crust and continental crust are made of different types of rock. The rocks in the continental crust do not contain as many of the heavier elements as the ones in the oceanic crust do.
Rocks in ocean crust are as old as how many years?
Rocks in ocean crust are generally as old as 200 million years. The oldest oceanic crust is found near continents, which can be around 250 million years old. However, most of the oceanic crust is continually being formed and destroyed through seafloor spreading and subduction, so rocks are often much younger.
What forms when 2 oceanic plates move apart?
Some move away from each other and create massive trenches normally in the sea bed, for example the Mariana Trench - 10,998 m.
What did geologists divide the world into?
The world is divided in many ways for descriptive purposes. Thus, the geologist classifies the crust by describing it as oceanic or continental. They've also described and named the layers of the Earth.
Can hot spots from only in oceanic crust?
Hot spots can occur in both oceanic and continental crust, not just in oceanic crust. They are caused by plumes of hot material rising from deep within the Earth's mantle, which can create volcanic activity. While many well-known hot spots, like the Hawaiian Islands, are located in oceanic regions, others, such as the Yellowstone hotspot, are found beneath continental crust. Therefore, hot spots are not limited to oceanic crust alone.
Is the theory of the continental drift true?
Continental Drift is an obsolete name for the theory of Plate Tectonics and yes, it is true. It has been proved in many ways, by comparing the composition of oceanic crust and its ages with that of the continental crust, by plotting the reversals of magnetism in the oceanic crust and many other ways.
