b.1. differentiate between instructive and extrusive igneous rocks
Extrusive igneous rocks reach surface still mostly liquid (lava) andintrusive igneous rocks cool down much more slowly while still buried.
Extrusive igneous rocks are usually fine grained or even glassy, and may have scattered larger crystals .intrusive igneous rocks, since they cool more slowly and uniformly, usually have an overal interlocked fabric of minerals without the size contrast.
Examples of instructive igneous rocks are granite and pegmatite ect. Examples of extrusive igneous rocks are pumice, tuff ect.
b2. magma and lava
magma is the molten rock stored in earths surface.
lava is magma which comes out when volcano erupts
b.3. metamorphic and sedimentary rocks
Sediments form very thin layers. Then these layers become harder over a long period of time. Those hardened layers of sediments are called sedimentary rocks. Example limestone and coal ect.
When existing rocks undergo changes due to high pressure and/or high temperature and/or high shearing stresses, metamorphic rocks are formed. Usually metamorphic rocks are formed deep in the earth. Heat comes from magma, while pressure comes from the layer of rocks on top of the other layers. Example slate and marble ect.
c.1 define core of the earth
The Earth's core is the part of Earth in the middle of our planet. It has a solid inner core and a liquid outer core.
c.3.what is metamorphic rock?
rock is subjected to very high heat and pressure, which cause obvious physical and/or chemical changes. Examples of these rocktypes include marble, slate, gneiss, schist.
my hand is paining plz some one help this guy
