ENDOGENIC PROCESSES

It is a mixture of molten or semi molten rock, volatiles and solids that is found beneath the surface of the Earth

• chemicals

• gases

• magma

• minerals

Besides molten rock, magma may also contain the following except:

• dissolved gas

• organic matter

• solid rocks

• suspended crystals

Magma originates in the lower part of the Earth's crust and in the upper portion of the mantle known as:

• asthenosphere

• outer core

• subduction zone

• vents

When magma emerges on the surface of the Earth , it is now called as:

• ash

• lava

• pyroclast

• tephra

what gives magma it's explosive character?

• gas

• molten rocks

• chemicals

• minerals

It refers to the resistance to flow

• combustibility

• ductility

• fluidity

• viscosity

magma extruded into the atmosphere as part of violent eruption solidifies in the air forming volcanic rock called as:

• Gas

• Lava

• Pyroclasts

• Tepra

Magma collects in areas called as:

• Vents

• Craters

• Caldera

• Magma Chamber

it involves the upward movement of the earths mostly solid mantle

• decompression melting

• transfer of heat

• flux melting

• extrusion

It is the portion of mantle where magma originates
