Why can we say there is just one ocean?

because the oceans all connect together

100

Surface wave transfers wind energy over a distance without moving matter. True or False?

True

100

Which water freezes at lower temperature? salt or fresh?

salt

100

What happens during evaporation?

water changes into water vapor

100

How can we help conserve the oceans?

  • pick up trash near beaches
  • avoid overfishing by catching only what is needed
  • keep drains free of chemicals and trash 
200

Which ocean is the largest and deepest?

Pacific Ocean

200

What is the main cause of  surface currents?

wind

200

__________ water mixes with air to help clean the air of pollutants

salt

200

What happens during precipitation?

water falls to Earth as rain, snow, sleet, or hail

200

Name 2 ways we can conserve fresh water

  • turning off the tap while brushing teeth
  • taking shorter showers
  • fixing leaking faucets
  • using a bucket instead of a hose when washing a car
  • watering plants early in the morning or late in the day
  • collecting rainwater to water plants
  • only running the dishwasher or washing machine when full
  • reusing water for plants instead of throwing away
  • washing pets on grass
  • cleaning driveways and patios with brooms instead of water
300

Which ocean is the smallest and shallowest?

Arctic Ocean

300

What determines the size of a surface wave?

  • strength of wind
  • how long wind blows
  • how far the wind has traveled
300

Mention sources of salt water

  • Oceans 
  • Seas 
  • Saltwater bays and gulfs (Gulf of Mexico, Persian Gulf)
  • Saltwater lakes (Great Salt Lake, Dead Sea)
  • Salt marshes
  • Estuaries (where rivers meet the ocean — a mix of fresh and salt water)
300

What happens during condensation?

water vapor cools and forms clouds

300

Why should we conserve water?

  • fresh water is limited
  • living things require water for life processes
  • ecosystems need clean, protected water sources
  • conserving water protects groundwater and rivers
  • God provides water through the water cycle as a blessing we should use wi
400

When a wave crashes onto the shore, wind energy is transformed into

sound energy

400

What makes the top of a wave crash onto the shore?

Gravity

400

Mention sources of fresh water

  • Rivers
  • Lakes
  • Streams and creeks
  • Ponds
  • Groundwater (aquifers underground)
  • Glaciers and ice caps
  • Rain, snow, sleet, and hail (precipitation)
  • Springs (freshwater flowing from underground)
400

Precipitation that gets soaked into the soil is called

groundwater

400

Why is it important to conserve the oceans?

  •  produce most of our oxygen
  •  help control Earth’s climate
  •  support many living organisms
  •  provide food and resources
  • oceans are part of God’s creation and should be cared for
500

Mention and show all the 5 oceans on the map

  • Southern
  • Arctic
  • Indian
  • Atlantic
  • Pacific
500

What makes a surface wave slow down near land?

Friction from the ocean floor

500

How do marine animals benefit from salt water?

  • echolocation sound travels well in salt water
  • salt water has minerals that some sea creatures can use to build strong shell
  • helps animals float more easily
500

Precipitation that moves on the surface of earth is called

runoff

500

What does conserving water mean?

  • preventing waste 
  • protecting water sources
  • using water wisely
