Having the right materiel and stick to it
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.

Answer:
Top to bottom:
- Polar
- Continental
- Arid
- Tropical
- Temperate
Explanation:
The world is very diverse when it comes to climate. This comes from numerous different factors, with one of the most important ones being the angle at which the sunlight falls on the surface. Some parts of the world are hotter, some colder, some milder, and in some parts, there is a lot of precipitation while at some precipitation is something rarely experienced.
At and near the equator, the climate is tropical, having constantly high temperatures, high humidity, and a solid amount of precipitation. Just north and south of the tropical climate we have the arid climate, characterized by very high temperatures, low humidity, and very low precipitation. The temperate climate is found in the mid-latitudes, bordering the tropical and arid climates, having pleasant temperatures for most of the year, and a medium amount of precipitation. The continental climate is found in the mid-latitudes and deeper into the continents, having extremely low temperatures in winter and high in summer, with precipitation being manifested through both rainfall and snowfall. Polar climate is found around the poles, and this climate is the coldest on average, the precipitation is also very low and when there is some it is manifested through snowfall.
