What is magma and lava?

What is Magma?

Ans:- Due to enormous pressure and temp erature the substance of the earth's interior remain liquid, being mixed with gas and vapour is called magma.

Short Ans:- molten rock material inthe earth 's interior is known as magma

What is lava?

Ans:- When hot molten magma of the earth's interior, comes out through the cracks and joints on the earth's surface, it is called lava As temperature rises a substance melts into liquid and increases in volume. On the other hand, when pressure increases, there happens to be a severe contraction in the same volume of mass. Both pressure and temperature are incredibly high in earth's interior.

Short Ans:- when this magma comes out to the earth's surface, it is as lava.

What is density and density of the earth.

What is density ? Density of a matter is its mass per unit volume. It is measured by the measure of its mass contained in one cubic centimetre of its volume. Density of a matter gives us an idea of how close, or how far apart, its molecules are. An iron plate feels heavier than an aluminum plate of the same volume, simply because iron is denser than aluminum.

An account to igneous rocks Granite: continental crust, Basalt:ocenic crust by research studys

An account to igneous rocks Granite: Continental crust is mainly formed of this Ba rock. It is composed of quartz, feldspar, mica and ro homblende and the colour of this rock varies from white, grey to pink. This is an impermeable rock. Granite is m very much resistant to erosion as it is heavy and very hard. Granite is coarse granied as the magma is cooled and solidified very slowly in the earths interior (diameter >3 mm). Landforms developed on the regions of granite rock are generally rounded and domal.
