a. igneous
b. metamorphic
c. sedimentary

question 2 of 18
any rock over time, has the chance to become another type of rock. (1 point)
a. true
b. false

question 3 of 18
weathering and erosion can happen to to any rock, in due time. (1 point)
a. true
b. false

question 4 of 18
a majority of the earths surface is sedimentary rock, because that is where the weathering takes place. (1 point)
a. true
b. false

Explanation:

• Question 1: Igneous rocks form from the cooling and solidification of magma (molten rock). When any solid rock is melted (becomes magma) and then cools and solidifies, it becomes igneous. Metamorphic rocks form from existing rocks under heat and pressure without melting. Sedimentary rocks form from the accumulation and lithification of sediments.
• Question 2: The rock cycle shows that any rock (igneous, sedimentary, or metamorphic) can, over time, be transformed into another type of rock through processes like melting (for igneous), heat and pressure (for metamorphic), or weathering, erosion, deposition, and lithification (for sedimentary).
• Question 3: Weathering (physical, chemical, biological breakdown) and erosion (transport of weathered material) are natural processes that can act on any rock over time. For example, granite (igneous) can be weathered by freeze - thaw cycles (physical weathering), limestone (sedimentary) can be chemically weathered by acid rain, and gneiss (metamorphic) can be eroded by wind - blown sand.
• Question 4: A majority of the Earth's surface is covered by sedimentary rock. Weathering occurs on all rocks, but sedimentary rocks form from the products of weathering (sediments) that are deposited, buried, and lithified.

Answer:

• Question 1: A. Igneous
• Question 2: A. True
• Question 3: A. true
• Question 4: A. True
