Distribution of Water & Oceans

Discover Earth's water! Learn about oceans, water cycle & properties.

Water Properties Match the water property to the correct definition or example. Polarity Opposite end of the water molecule have opposite charges. Cohesion Water attracts to other water molecules, allowing water to form droplets. Adhesion Water attracts to other materials, like plant roots absorbing water against the flow of gravity. Surface Tension Water has a tighter attraction at the surface, creating a skin-like barrier. Specific Heat Water heats up and cools down slowly. Hard water is rich in which minerals? Calcium and Magnesium Chlorine and Manganese Magnesium and Sodium Lithium and Phosphorus Which property allows plants to soak in water through their roots? Buoyancy Capillary Action Specific Heat Density River Basins and Watersheds Answer the questions about river basins and watersheds. Put the words in the correct blanks. River Basin: The land water flows across or under as it moves to a major river.Watershed: Areas of land that drain to smaller rivers and streams in the basin. Water Distribution Answer the multiple choice questions about the distribution of water on Earth. What percent of Earth's hydrosphere is salt water? 30% 50% 70% 97% What percent of Earth's surface is covered in water? 30% 50% 70% 97% The majority of Earth's freshwater can be found where? In aquifers underground Frozen as polar ice In the atmosphere as vapor In surface water like rivers and lakes Water Cycle Label the water cycle with the correct tags.Word Bank: Condensation, Evaporation, Percolation, Precipitation, Runoff Evaporation Condensation Precipitation Percolation Runoff Which best describes the role of the water cycle? It circulates existing water on Earth. It increase the supply of usable water on Earth. It reduces pollution in most of Earth’s water. It removes excess water from Earth. Which statement best compares the amount of water present on Earth today, with the amount millions of years ago? There is slightly more water available today. There is significantly more water available today. There is significantly less water available today. There is relatively the same amount of water available. Why is freshwater in short supply on Earth? Most of it is frozen. Most of it is in the atmosphere. Most of it is polluted. Most of it is underground in impermeable rock. Ocean Zones Match the ocean zone to the description. Intertidal Where the sea meets the land. Organisms are adapted to tides and waves. Neritic Sea floor slopes downward, and water is warmed by sunlight. Home to corals, colorful fish, sea turtles, dolphins, etc. Oceanic Open ocean, where phytoplankton is the major producer. Home to free swimming creatures. Benthic Deep ocean, home to chemosynthetic communities that support extremophiles. Ocean Currents, The Deep Ocean, Ocean Technology Answer the questions about ocean currents, the deep ocean, and ocean technology. Fill in the blank with the correct vocabulary term. -Upwelling: Cold, nutrient-rich water from the deep ocean rises to the surface creating ideal conditions for aquatic life to feast and reproduce.-Hydrothermal Vents: Hot water geysers spewing mineral rich water from the seafloor, supporting chemosynthetic bacteria that serve as the foundation of benthic communities.-Cold Seeps: Methane, and other hydrocarbon rich fluid, escape the sea floor due to tectonic plate pressure, providing chemical for chemosynthesis in benthic communities.-SONAR: The use of sound waves to map the seafloor and locate objects in the deep ocean.-Submersibles: Human-occupied or robotic vessels that allow scientists to study the deep ocean. The most famous is Alvin, which discovered hydrothermal vents in the late 1970s. Which causes cold ocean water to rise during an upwelling event? Motion of organisms. Mass of nutrients. Deep water currents. Surface winds. Deep sea submersibles aided in the discovery of this deep ocean process? Chemosynthesis The Water Cycle Photosynthesis The Nitrogen Cycle Which contributes most in supporting life on the deep ocean floor? Cold water temperatures. Lack of predators. Extreme water pressure.
