How are Organic Sedimentary Rocks formed?

There are 2 organic sedimentary rocks

1. How are organic sedimentary rocks formed?

2. Organic sedimentary rocks form from the accumulation of plant or animal debris.  2

3. Two kinds of sedimentary rock are made up of organic material: coal and oil . 3 coal o il

4. 4 Coal is made of terrestrial vegetation. Millions of years ago, vegetation accumulated in swamps. Eventually, the vegetation was buried in the Earth’s crust, without air. Then, heat, pressure and bacteria changed it into coal. This type of rock is found in continental environments such as forests.

5. 5 Oil is made of marine plant and animal remains. . Some sedimentary rocks contain oil. Millions of years ago, microscopic marine animals and plants ( plankton ) fell to the bottom of the sea. Sediment accumulated on top of this organic material. The material was buried underground without air. Eventually, heat, pressure and bacteria slowly changed the organic material into oil .

6. REVIEW D efine sedimentary rocks State the importance of taking care of mother nature with the emphasis on the benefits of fossil fuels 6

7. Group Activities 7 On your notebook, your group will make a summary of today’s lesson about sedimentary rocks that are made up of organic material: coal and oil O n your notebook, illustrate coal and oil As a group, you will create a Venn diagram to reflect the similarities and differences of Coal and Oil
