Igneous rock are formed by the cooling and crystallization of molten rock and are formed by the cooling of magma above earth's surface.
Let's look into the statements one by one:
Igneous rocks are formed only from material ejected during a volcanic eruption.
-This is not true because igneous rock can also be formed by the cooling down of magma inside a volcano or magma that was trapped in the crack of crust.
Igneous rocks are formed by the cooling and crystallization of molten rock.
-This is correct.
Igneous rocks are produced by the weathering and transport of pre-existing rocks.
-This is incorrect as igneous rock is formed by volcanism. The rock that are formed with the statement is sedimentary rock.
Igneous rocks are formed by the cooling of magma above earth's surface and lava below the surface.
-This is correct. Both intrusive and extrusive volcanic activity forms igneous rock after cooling down.
Igneous rocks are formed by recrystallization
-This is not true as recrystallization does not take place in the formation of the igneous rock. The rock formed by recrytillization is metamorphic rock.
Therefore,the igneous rock are formed by the cooling and crystallization of molten rock and are formed by the cooling of magma above earth's surface.
Hope it helps!
The main reason, which I have read about in some books, is that they do not permit industrial building on those islands, so who would want to live there? It is a very bare bones society.
<span>the country that is not dircetly situated next to a sea or ocean is : C. Laos
Laos is a country in south east asia that is located entirely by land. On its southern border it covered by Thailand, Myanmar border its eastern part, Yunnan borders its northern part and its western part is bordered by VietnamHope this helps. Let me know if you need additional help!</span>
It was Carl O. Sauer who did
The climate 250 mya was very tropical, so maybe those fossils could've been found there even w/o continental drift
