The density of basalt is around 3 grams per cubic centimeter. In contrast, the mantle is made of peridotite, which has a density of about 3.3 grams per cubic centimeter. Therefore, when the mantle partially melts and re-crystalizes as basalt, the oceanic crust will sit on top of the mantle.

The average density of granite is 2.7 grams per cubic centimeter (your particular granite may vary slightly, so if you want a high level of accuracy, you should measure it, weight divided by volume equals density). If you have the dimensions of granite plate, you can calculate the volume of that plate; length x width x thickness = volume.

Basalt is a major rock type that occurs in virtually every tectonic setting. Basalt is clearly the most common volcanic rock on Earth and basaltic rocks (including gabbro, diabase and their metamorphosed equivalents) are the most common rocks in the crust 2.Basalt is also common on the Moon and other rocky planets of the Solar System.

Various planes of the earth have a variety of materials, all having peculiar attributes attached to them. Factually, density is one of the primary reasons for the formation of the different planes in the earth. Mathematically, density is known as the mass over volume. So, in essence, thickness could be seen as how weighty a substance is.

Basalt is the most widely distributed basic extrusive rock, with a SiO 2 content ranging from 45% to 52%, and is mainly composed of basic plagioclase and monoclase pyroxene, followed by orthopyroxene, peridot and amphibole. Pyroxene in basalt often has a complete crystalline, short columnar structure; plagioclase in basalt has a fine needle-like nondirectional arrangement.

Density Contrast- basaltic magmas have densities on the order of 2600 to 2700 kg/m 3, whereas rhyolitic magmas have densities of 2300 to 2500 kg/m 3. This contrast in density would mean that the lighter rhyolitic magmas would tend to float on the heavier basaltic magma and inhibit mixing.

Why does copper have a high density? Answer. The density of elements going from left to right in the periodic table increase in density up to the element copper.

The atoms and molecules in a solid have fixed positions. They don't move around like atoms or molecules in a gas or liquid do. Density is a tangible property that is often correlated with chemical composition. The density of matter is communicated in the form of mass per unit of volume. Solids have a definite shape and volume can't flow.
