Investigating the Natural World

How are Sedimentary Rocks formed?

• Cooling and Hardening
• Heat and Pressure
• Compacting and Cementing
• Melting

Where can the oldest layer be found?

• The top layer
• The middle layer
• They are all the same age
• The bottom layer

How are fossils created?

• Traces of organisms get turned into stone.
• Dead organisms are quickly buried for millions of years.
• Animals get trapped.
• All of the above

What are the 3 main fossil fuels?

• Coal, Oil, and Gasoline
• Coal, Oil, and Natural Gas
• Electricity, Gasoline, Petroleum
• Coal, Oil, Non-renewable Resources

Fossils give us evidence about which of the following?

• plants and animals that lived long ago
• how weathering and erosion break down rocks
• the other planets in our solar system
• the transfer of energy from one form  to another

Finding the fossils of trees in an area that is currently a desert without much life might tell us that the area, millions of years ago - 

• was heavily eroded by strong winds
• received enough rain to support a forest
• suffered very powerful earthquakes
• was destroyed by the impact of meteorites

What is it called when plants give off water vapor as a waste product?

• condensation
• evaporation
• sublimation
• transpiration

Weathering is the process of....

• Breaking down rock into smaller and smaller pieces of sediment.
• The movement of sediment
• Placing sediment into a new location.
• None of the above

What process most likely caused this formation?

• Wind erosion
• Water erosion
• Wind Deposition
• Wind Weathering

What is the process of sedimentary rock formation?

• Sediments are laid in a new location and layers build up over time. Pressure and cementation pack the layers together.
• Sediments are laid in a new location and layers build up over time. Pressure and heat pack the layers together.
• Rocks are formed out of lava
• Rocks are formed from other rocks.
