Grade 4 Oceanography and Hydrology
Earth's surface is made up of about 70% water.
  1. True
  2. False
Grade 4 Oceanography and Hydrology
The diagram shows the processes in the water cycle.
Water Cycles Simple
Which letter best represents evaporation?
  1. A
  2. B
  3. C
  4. D
Grade 4 Oceanography and Hydrology
Waves change a shoreline by erosion and                .
  1. condensation
  2. precipitation
  3. deposition
  4. evaporation
Grade 4 Oceanography and Hydrology
Erosion makes beaches smaller because it
  1. carries sand and sediment away from the shore.
  2. deposits sand and sediment near the shore.
  3. breaks up sediment into smaller pieces.
  4. fills the ocean with sand and sediment.
Grade 4 Oceanography and Hydrology
Earth's water
  1. is mostly in its vapor state at any given time.
  2. has been recycled for billions of years.
  3. freezes as it rises into the atmosphere.
  4. only falls to Earth as rain.
Grade 4 Oceanography and Hydrology
In the water cycle, what happens during evaporation?
  1. water vapor changes to liquid water
  2. water falls to the ground from clouds
  3. liquid water changes to water vapor
  4. water flows over the ground
Grade 4 Oceanography and Hydrology
The movement of water from Earth's surface, through the atmosphere (air), and back to Earth's surface is called the               water cycle              .
Grade 4 Oceanography and Hydrology
Condensation is when water changes from a liquid to a gas.
  1. True
  2. False
Grade 4 Oceanography and Hydrology
Use the diagram of the hydrologic cycle to help fill in the blanks in the paragraph.
Water Cycles Simple

First, a water droplet              evaporates             , it becomes water vapor in the air. Next, the water vapor             condenses             to become a cloud, fog, or mist. Then the condensed water droplets               precipitate               back to Earth as rain, snow, sleet, or hail. On Earth, the water often flows into                  rivers/streams                  and flows out to a large body of water like a lake or an ocean. Water can also seep into the ground, through loose soil or cracks, and become               groundwater              .
Grade 4 Oceanography and Hydrology
What is the flow of water during and after precipitation called?
  1. condensation
  2. precipitation
  3. evaporation
  4. runoff
Grade 4 Oceanography and Hydrology
The stage of the water cycle where the water vapor (gas) turns back into liquid drops creating clouds is called                .
  1. condensation
  2. precipitation
  3. evaporation
  4. runoff
Grade 4 Oceanography and Hydrology
Rain, sleet, hail, and snow are all part of the                 process in the water cycle.
  1. transpiration
  2. evaporation
  3. precipitation
Grade 4 Oceanography and Hydrology
                provides the energy for the water cycle.
  1. The Moon
  2. The Sun
  3. The atmosphere
  4. An ocean wave
Grade 4 Oceanography and Hydrology
The map shows the Atlantic Ocean. It also shows the continents it borders.
Map of the Atlantic
Which statement best describes continents and oceans?
  1. all continents are surrounded by oceans
  2. some continents are surrounded by oceans
  3. continents are not surrounded by oceans
Grade 4 Oceanography and Hydrology
A large deposit of material from a river into the ocean forms an area called a                .
  1. peninsula.
  2. delta.
  3. dune.
  4. beach.
Grade 4 Oceanography and Hydrology
The stage of the water cycle where water turns into a gas called water vapor is called                .
  1. condensation
