Rocks, Minerals, Soil, Fossils! Let’s review.

1. Rocks, Minerals, Soil, Fossils! Let’s review.

2. If you were a tomato plant, what type of soil would you most likely want to grow in? • Sand • Clay • Loam • Silt

3. From the surface, digging down, in what order would you find the three main categories of dirt here on earth. • Subsoil, topsoil, bedrock • Topsoil, subsoil, bedrock • Bedrock, topsoil, subsoil • Topsoil, bedrock, subsoil

4. Which type of soil is made up of the smallest particles? • Sand • Silt • Clay

5. Which type of soil is made up of the largest particles? • Silt • Sand • Clay

6. Which type of soil is made up of dead plant and animal parts? • Sand • Silt • Clay • Humus

7. Which layer of soil is the best to grow plants in? • Bedrock • Subsoil • Topsoil • Sand

8. What kind of rock are you most likely to find fossils in? • Igneous • Sedimentary • Metamorphic • granite

9. The process of rocks breaking apart in nature, over time, is called • Erosion • Fossilization • Weathering • exploration

10. What are the three main types of rocks? • Granite, diamonds, mica • Sandstone, limestone, feldspar • Metamorphic, igneous, sedimentary • Rocks, minerals, fossils

11. All rocks are • Made up of minerals • Expensive when they are made into jewelry • Pretty • Worth money

12. Minerals are best defined as • Rocks in the ground • A solid, found in nature, that is not living • Good to eat • Things are different colors

13. What type of rock has been changed by pressure and temperature – or heat? • Sedimentary • Metamorphic • Igneous

14. What do we call the washing away and wearing away of soil over time – for example, in a flood? • Excessive rain • Flooding • Erosion • metamorphosis

15. Sedimentary rock forms by which of the following processes? • Erosion • Breaking apart • Heating and hardening • layering

16. Extinct means • No longer in existence – all gone forever • Endangered • Imaginary • Very rare

17. What evidence lets us learn about things that are now extinct? • Fossils • The internet • Bill Nye the science guy • Sponge Bob Square Pants

18. What are three attributes of rocks that scientists observe, in order to identify and classify rocks? • Green, red, blue • Texture, feeling, smell • Color, texture, hardness • Harness, softness, chalkiness

19. What might you conclude if you found fossils of sea shells outside your school? • The beach is close by. • Shells are so cool! • The area at the school was underwater millions of years ago. • The area at the school was never near water

20. A ditch on the playground, where the water runs from the pavement keeps getting deeper, and deeper and wider and wider each time it rains. What is causing this? • Kids are digging the dirt. • Rain water is eroding the land near the ditch. • Bulldozers must be working near the ditch. • The ditch needs to be deeper.

21. Fossils are not found in metamorphic rock because • All metamorphic rock is under water. • Animals don’t like metamorphic rock. • Metamorphic rocks are never found. • Metamorphic rocks are made with pressure and heat, which would destroy any fossils.

22. If you found hot weather animal fossils in a place on earth that is now very cold and covered with ice, you might conclude • That the weather was much warmer there millions of years ago. • That the temperature was the same everywhere. • That the animals were lost. • That polar bears are really cute.

23. The hardened remains of a living thing that lived long, long ago (plant or animal) are called • Erosion • Fossils • Rocks and minerals • metamorphic
