How Metamorphic are form?
Weathered products of existing rocks are transported , deposited , compacted , and cemented.
What would you expect to see underneath the layer of granite?
Well, beneath granite you would find any layer of Mafic igneous rock. Basalt is the most common Mafic rock, so that's a good start. It's what you will typically find forming the ocean floor as well as the heavy layer of the earth's crust beneath the granitic layers.
How heavy is the planet of Neptune?
1.0243×1026 kg 17.147 Earths
What is the crusts thickness?
There are two types of crust's. I dont know which one you are talking about, but it is probably the continental crust. The other type of crust is the Oceanic crust. The first continental crust is about 4-7 miles (6-11 km) thick and mainly consists of heavy rocks, like basalt. The Continental crust is thicker than the Oceanic crust, about 19 miles(30 km) thick. It is mainly made up of light material like granite.
What elements are found on earth crust?
There are various parts that consist the earth's crust. It is mainly made up of two parts namely the lighter granite-based continental crust and the heavy basaltic oceanic crust. Some of the elements in the earth's crust include oxygen, silicon, magnesium, iron and so many more.
Where is the thinnest point of the earths crust?
It is beneath the sea an is called a ocean crust. This is the thinnest point because the ocean water is so dense (heavy) it flattens the crust (because there's millions and millions of gallons of water...... That's heavy!!!) that's why there are oil rigs at sea because it's only around 5 kilometres thick, unlike on land it's around 50 kilometres thick!!!
What is the layer of heavy rocks beneath the Earth's crust?
The upper mantle.
What is the earth's crust the outer lighter portion of?
The earth's crust is the outer lighter portion of the continental crust. The crust beneath the ocean iscomosed of heavy, dark volcanic rock. The continental crust is composed mostly of lighter rocks rich in silica such as granite.
Why do geologist think earths core contains mostly iron?
Other orbiting bodies contain more iron then earths crust does
How can such heavy things as the continents float?
Continents float because the rock beneath them is denser then the surface rocks The surface rocks are poorer in iron than the deeper layers. The continents are made mostly of silica rich rock, which is less dense than oceanic crust, so when the two come in contact, the oceanic crust sinks beneath the continent.
How Metamorphic are form?
Weathered products of existing rocks are transported , deposited , compacted , and cemented.
Why do scientist think earth's core contains iron?
Samples of Earth's crust contain less iron than found in meteorites, and iron is a comparatively heavy element that would have sunk into the planet when it was being formed.
