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.

False....I believe at least its false<span />
The hot and humid climate
Answer:
C. Principle of original horizontality
Explanation:
The Law of Original Horizontality suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed. This allows us to infer that something must have happened to the rocks to make them tilted.
Answer:
There are many natural resources found in Latin
America that can be used for industry. Three examples of these resources are fertile soil, minerals, and the Amazon Rainforest. Fertile soil can be used in farming and ranching industries. Farmers can grow important cash crops, such as coffee, soybeans, and tropical fruits. Ranchers can use the land to raise and breed cattle, one of the leading industries in Brazil. Though these are important industries in Latin America, if people can create environment challenges to the soil if they are not careful. Possible challenges include soil exhaustion, erosion, deforestation, and water contamination from pesticides. A large supply of minerals has led to the development of the mining industry, which is very important to countries like Chile, Colombia, Argentina, and Peru. Though mining creates economic stability, it also creates environmental challenges! Issues such as water pollution (with toxins like mercury and bauxite) and air pollution (from heavy machinery) are common. The Amazon Rainforest itself is an amazing natural resource that allows for industries like mining, farming, ranching, and logging. However, if left unchecked, these industries can create environmental challenges such as deforestation, water contamination, air pollution, and the extinction of plant and animal species.
