Science 8: Unit 5 - Fresh and Saltwater Systems MEGA QUIZ

What is a continental glacier?

What is a valley glacier?

Things left by a valley glacier: - Valley glaciers erode bowl-shaped basins called [blank_start]cirques[blank_end]. - If two or more glaciers erode the top of a mountain at different directions, a ridge called an [blank_start]arete[blank_end] or a peak called a [blank_start]horn[blank_end] can form. - Valleys eroded by glaciers will be [blank_start]U[blank_end]-shaped.

Fill in the blanks to the Water Cycle: Water from the earth's surface and waters [blank_start]evaporate[blank_end] and rise into the atmosphere in the form of [blank_start]water vapor[blank_end]. It then [blank_start]condenses[blank_end] back into liquid and falls in the form of [blank_start]precipitation[blank_end].

Name the FIVE main sources of water on planet earth.

What is streamflow?

What is deposition?

Why is having too much sediment in a river unhealthy?

How much salt content is in every 1000g of water?

Things to know about the ocean and tectonic plates: - The [blank_start]salinity[blank_end] is the amount of salt content in the water. - A large dropoff in the middle of the ocean is called a [blank_start]continental slope[blank_end] because that is where the tectonic plate ends. - A flat, shallow part of the ocean that is still a part of the continent. It is called a [blank_start]continental shelf[blank_end]. - Ocean [blank_start]ridges[blank_end] occur when two tectonic plates compress. It is common for magma to erupt from it. - [blank_start]Trenches[blank_end] occur when two tectonic plates overlap. This can create mountains.

The ocean's salt comes from rivers picking it up from the ground and collecting it.

Ocean ridges can be up to 2000km wide
