Sedimentary Rocks
Correct Answer
A. Sedimentary RocksExplanation
Fossils are often found in sedimentary rocks because these rocks are formed from layers of sediment that accumulate over time. As new layers of sediment are deposited, older layers are compressed and hardened, preserving any fossils that may be present. Sedimentary rocks are commonly found on the Earth's surface, making them accessible for fossil discovery. Caves, underground, and the ocean may also contain fossils, but sedimentary rocks are the most reliable and common source for finding them.Rate this question:

Fossils are only found in ____________________________________ .
-
Intrusive igneous rocks
-
Foliated metamorphic rocks
-
Sedimentary rocks
-
Nonfoliated metamorphic rocks
Correct Answer
A. Sedimentary rocksExplanation
Fossils are only found in sedimentary rocks because sedimentary rocks are formed through the accumulation and cementation of sediments, which can preserve and fossilize organic remains such as plants, animals, and other organisms. Intrusive igneous rocks are formed from the cooling and solidification of magma beneath the Earth's surface, and they do not typically preserve fossils. Foliated metamorphic rocks are formed through the recrystallization of pre-existing rocks under high pressure and temperature, which can cause the destruction of fossils. Nonfoliated metamorphic rocks are also formed through the recrystallization of pre-existing rocks, but without the development of a layered or banded texture, making it less likely for fossils to be preserved. Therefore, sedimentary rocks are the most suitable environment for the preservation of fossils.Rate this question:

Metamorphic rocks are the oldest known rocks.
-
True
-
False
Correct Answer
A. TrueExplanation
Metamorphic rocks are the oldest known rocks because they are formed from pre-existing rocks that have undergone intense heat and pressure over millions of years. This process of metamorphism causes the minerals and textures of the rocks to change, resulting in the formation of new rocks. As metamorphic rocks are formed from older rocks, they are generally considered to be older than sedimentary and igneous rocks. Therefore, the statement that metamorphic rocks are the oldest known rocks is true.Rate this question:

The type of metamorphism that occurs over large areas, commonly at convergent plate margins, and is responsible for the production of most metamorphic rocks is ____________________.
Correct Answer
regionalExplanation
Regional metamorphism is the type of metamorphism that occurs over large areas, commonly at convergent plate margins. It is responsible for the production of most metamorphic rocks. This type of metamorphism is characterized by high temperatures and pressures, which result from the collision of tectonic plates. As the plates converge, rocks are subjected to intense heat and pressure, causing them to undergo significant changes in mineralogy, texture, and structure. This process can lead to the formation of new minerals and the recrystallization of existing ones, resulting in the creation of regional metamorphic rocks.Rate this question:
