GEOLOGY

Detailed explanation-1: -Inside an active volcano is a chamber in which molten rock, called magma, collects. Pressure builds up inside the magma chamber, causing the magma to move through channels in the rock and escape onto the planet’s surface. Once it flows onto the surface the magma is known as lava.

Detailed explanation-2: -Magma is a molten and semi-molten rock mixture found under the surface of the Earth. This mixture is usually made up of four parts: a hot liquid base, called the melt; minerals crystallized by the melt; solid rocks incorporated into the melt from the surrounding confines; and dissolved gases.

Detailed explanation-3: -As it rises, the magma collects fragments of rocks, like floodwaters picking up silt and gravel. Some of these fragments contain diamonds. (Related: “World’s Oldest Diamonds Discovered in Australia.")

Detailed explanation-4: -Molten rock below the surface of the Earth that rises in volcanic vents is known as magma, but after it erupts from a volcano it is called lava. Magma is made of molten rock, crystals, and dissolved gas-imagine an unopened bottle of soda with grains of sand inside.

Detailed explanation-5: -The molten liquid that gets erupted out of the surface of the Earth is termed as lava. Lava is also referred to as liquid magma. The temperature of magma is slightly hotter and ranges from 1300 to 2400 degrees Fahrenheit. The temperature of lava is slightly colder and ranges between 1300-2200 degrees Fahrenheit.
