WELCOME TO OUR LESSON ABOUT... SEDIMENTARY ROCKS!

QUIZ! Let's start with a quiz to see what you guys already know.

1. Where are Sedimentary rocks formed? 2. How are Sedimentary rocks formed? 3. Is Limestone a Sedimentary rock? 4. What does erode mean? 5. Do Sedimentary rocks have layers? 6. Where are they found? QUESTIONS

Now that we’re done with that little quiz, let’s move on to the lesson. LESSON TIME!

Sedimentary rocks are formed when pieces of the earth get eroded (broken down) into tiny pieces by wind and water, and those pieces get pushed together on the grounds of water sources. They are also found by water sources. How are they formed?

Here are some examples of sedimentary rocks. : 

Here are some examples of sedimentary rocks. Examples

Conglomerate is made up of rounded pebbles cemented together. Conglomerate

Sandstone is sand grains cemented together. Sandstone

Siltstone is made from silt particles cemented together. Siltstone

Shale is made from silt particles cemented together. It is similar to siltstone but with even finer grain size. Shale

Limestone is made primarily of calcium carbonate or calcite. Limestone

Here are some uses of these rocks Uses

It is used in construction and also polished to make ornaments. Conglomerate

It is used in the construction of buildings and monuments. You can use sandstone in concrete and tiles. Sandstone

Siltstone is of very little use other than a contributor to soil. Siltstone can also be used in sculptures and buildings. Siltstone

Shale is used, along with other rock minerals, in themanufacture of brick. Shale

Used as counter tops and flooring. It is also used to make paper white. Limestone
