What else can I help you with?
Why is there less silica in ocean water than river and ground water?
almost no silica in ocean water but most of its the earths crust.
Where is most of the earths new crust found?
Most of Earth's new crust is found along mid-ocean ridges, underwater mountain ranges where tectonic plates are moving apart. This is where magma rises from the mantle to create new crust through volcanic activity.
What rock type is most abundant in the crust of the ocean floors?
The most abundant rock type in the ocean floor crust is basalt. This volcanic rock forms from the rapid cooling of lava at mid-ocean ridges and is a key component of oceanic crust. Basalt is typically dense and rich in iron and magnesium, distinguishing it from the continental crust, which is primarily composed of lighter granitic rocks.
What is the theory that earths crust is in a slow motion?
Plate Tectonics. The crust is in large, irregular plates shuffling around by new rock extruded from the upper Mantle in ocean plate boundaries, balanced by the loss of the fringes of the ocean-floor plates to subduction.
What is caused by the earths plate or crust?
Earth's plates or crust can cause earthquakes, volcanic eruptions, and the formation of mountain ranges due to tectonic plate movements and interactions. Subduction zones can also lead to the formation of deep ocean trenches and volcanic arcs.
Why the oceans floor is considered part of Earth's crust?
earths crust includes ocean floors and
The layer of the earths crust that is not covered by ocean water is called what?
continental crust
What covers about three fourths of the earths surface and most of the ocean floors?
water
Which earths layer includes the land that that make up the continents and land under the ocean?
this is the crust which is the very thin layer which has land in the water
Which earths layer includes the land that make up the continents and land under the ocean?
The layer that includes the land making up continents and the land under the ocean is the crust, which is the outermost layer of the Earth's surface. It is divided into continental crust, which forms the continents, and oceanic crust, which lies beneath the oceans.
What is the uppermost layer of the earth?
The uppermost layer of the Earth is called the crust. It is divided into two types: continental crust, which makes up the landmasses, and oceanic crust, which forms the ocean floors. The crust is thinnest under the oceans and thickest under mountain ranges.
Where can you find sodium in earth or ocean?
Sodium is found in the Earths crust!! But i don't know about the ocean!! And Sodium is salt!!
How and why does the earths crust vary from place to place?
The earths crust its 5-70km deep in the ocean and upto 100km deep at mountain ranges. At certain areas, the crust is unstable due to moving plate tectonics.

Why are ocean floors the newest crust on the earth?
The reason for this is that the ocean floor is ever changing and is never in the same possition due to current.
Where is crust located?
The Earth's crust is the outermost layer of the Earth. It is divided into two types: continental crust, which forms the continents, and oceanic crust, which forms the ocean floors.
Does the earths crust extend deeper below the continents or below the ocean basins?
Earths crust extend deeper below the continents than below the oceans basins (or at least this is what I think).
