Resource summary

Question 1

Question
What is a continental glacier?
Answer
  • Glaciers that are formed in a mountain range
  • Huge mass of ice and snow, creating a glacier
  • A large body of saltwater
  • A large body of freshwater

Question 2

Question
What is a valley glacier?
Answer
  • A large body of saltwater
  • Resulting from large calving off a continental glacier
  • Glaciers that are formed in a mountain range
  • Huge mass of ice and snow, creating a glacier

Question 3

Question
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.
Answer
  • cirques
  • arete
  • horn
  • U

Question 4

Question
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].
Answer
  • evaporate
  • water vapor
  • condenses
  • precipitation

Question 5

Question
Name the FIVE main sources of water on planet earth.
Answer
  • Glaciers, plants
  • Ice, glaciers
  • Precipitation
  • Groundwater, surface water
  • Oceans, aquifer
  • Oceans, seas
  • Rivers, streams
  • Mountains
  • Lakes, ponds

Question 6

Question
What is streamflow?
Answer
  • Resulting from large calving off a continental glacier
  • A large body of saltwater
  • Upstream area of a watershed where the water originates
  • Amount of water discharged from a watershed

Question 7

Question
What is deposition?
Answer
  • Amount of water discharged from a watershed
  • A large body of saltwater
  • When sediments in a river settle to the bottom
  • A large body of freshwater

Question 8

Question
Why is having too much sediment in a river unhealthy?
Answer
  • It can cause more floods
  • Sediment can transport pollutants
  • It can slow the river's speed
  • A and C only

Question 9

Question
How much salt content is in every 1000g of water?
Answer
  • 35
  • 43
  • 78
  • 16

Question 10

Question
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.
Answer
  • salinity
  • continental slope
  • continental shelf
  • ridges
  • Trenches

Question 11

Question
The ocean's salt comes from rivers picking it up from the ground and collecting it.
Answer
  • True
  • False

Question 12

Question
Ocean ridges can be up to 2000km wide
Answer
  • True
  • False
