Essential Question: How is sedimentary rock formed?

Write your claim using the sentence stem.

"Sedimentary rock is formed by..."

Multiple Choice

What is the main purpose of evidence in a scientific investigation?

• To support a claim

• To make a guess

• To tell a story

• To create confusion

Dropdown

Sedimentary rocks are made from

Select answer

, which are tiny grains of sand, pebbles, or bits of shells and plants.

Multiple Choice

Why are sedimentary rocks compared to 'scrapbooks' of our planet?

• Because they are colorful

• Because they are made of layers containing bits and pieces of history

• Because they are found near volcanoes

• Because they are made of metal

Multiple Choice

Explain the difference between weathering and erosion as described in the lesson.

• Weathering breaks rocks into sediment but erosion carries the sediment.

• Erosion breaks rocks into sediment but weathering carries the sediment.

• Weathering breaks rocks into sediment and erosion drops sediments.

Multiple Select

Which of the following are steps in the formation of sedimentary rocks?

Select all that apply.

• Weathering

• Erosion

• Melting

• compaction

Multiple Choice

What is the process called when sediment settles to the bottom in a flat layer after wind slows down or a river flows into the ocean?

• Compaction

• Deposition

• Cementation

• Erosion

Multiple Choice

Which of the following statements about sedimentary rock formation is correct?

• Cementation happens before compaction.

• Compaction removes air and water from sediment layers.

• Deposition glues sediments together.

• Cementation squeezes sediments.

Dropdown

Sedimentary rocks are formed when small bits of materials are pressed together in

Select answer

.

Multiple Choice

• Sandstone

• Shale

• Limestone

• Granite

Based on the lesson, is your claim valid? Let's write a reasoning statement including evidence from the lesson. Use the sentence stem to help you get started: 'My claim is valid because the lesson explains...'

Multiple Choice

Why are fossils only found in sedimentary rocks rather than other types of rocks?

• Because sedimentary rocks form gently in layers and can preserve shapes without melting or crushing them.

• Because sedimentary rocks are the hardest type of rock.

• Because sedimentary rocks contain more minerals than other rocks.

• Because sedimentary rocks are found only in deserts.
