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.

· Irrigation schemes are a necessity in many countries as they supply the countries with sufficient water to produce food to meet their increasing food demand (Fanadzo, 2012).In South Africa, the Vaalharts Irrigation Scheme (VHIS) is a large irrigation scheme utilising water from the Vaal River via numerous gravity fed canals ().The return flow from the VHIS enters the Harts River (via numerous ...
Explanation:
Answer:
well there's so many factors influencing temperatures like we have clouds in a cloudless place the temperature will be low as the clouds will be absorbing the rays from the sun while in a place where we have no clouds the temperatures will be really high during the day and called in the light then we also have nearness to large water bodies places near large water bodies experience high temperatures while those that are far experience low temperatures we also have altitude places with high altitudes experience low temperatures while places with low altitudes experience high temperatures
The altitude ranges from 500 ft to 11500 ft
