12/4 BR: Rocks & Fossil Questions

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock formed by the accumulation and compaction of mineral and organic particles, often containing fossils.

Front

How does sedimentary rock become igneous rock?

Back

Sedimentary rock becomes igneous rock when it is melted into magma and then cooled down.

Front

What is mineralization (petrification)?

Back

Mineralization (petrification) is the process where an organism's tissue is replaced by minerals, turning it into a fossil.

Front

Why can sedimentary rocks form fossils?

Back

Sedimentary rocks can form fossils because the minerals in the sediment seep into the organism and aid in fossilization.

Front

What can scientists infer from finding a fish fossil in the desert?

Back

Scientists can infer that the area was once covered by water long ago.

Front

Why are fossils not found in igneous rocks?

Back

Fossils are not found in igneous rocks because magma burns and destroys all presence of ancient organisms.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation and transformation, including the processes of erosion, sedimentation, and metamorphism.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as wind or water.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken-down materials.
