Ocean
| Question | Answer |
|---|---|
| What is the zone of the ocean that is closest to the surface? (It is where most ocean life lives.) | The sunlight zone |
| What is the zone of the ocean that is 2nd closest to the surface and has some/little light? (Some large predators hunt here.) | The twilight zone |
| What is the 2nd deepest zone of the ocean that has basically no light? (Animals eat dead remains here; there are no plants.) | The midnight zone |
| What is the deepest zone of the ocean? | The abyss |
| What is the part of the ocean floor that connects to continents, is shallow, and is where people swim? | Continental Shelf |
| What part of the ocean floor is the drop to the deeper parts of the ocean? | Continental Slope |
| What part of the ocean floor is at the bottom of the drop and is a transition to the flat bottom? | Continental Rise |
| What part of the ocean floor makes up the flat bottom of the ocean and makes up most of the ocean floor? | Abyssal Plain |
| What part of the ocean floor is like a deep canyon at the bottom of the ocean floor? | Trench |
| What are bulges in the oceans caused by the moon's gravitational pull? | Tides |
| What are paths or "rivers" of water moving through the ocean? | Currents |
| What are three causes of currents? | Wind, temperature, and salinity |
| Which current brings warm water from the equator and keeps the water along east coast of the US warmer? | Gulf Stream Current |
| About how much of the earth is covered by water? | 70% |
| What tool do we use to learn about the ocean floor? | Sonar |
| What is SONAR? | It sends out sound waves and measures the time it takes to bounce back to gather information about the depth and surface of things like the ocean. It stands for SOund Navigation And Ranging). |
| These are free-floating, microscopic organisms | Plankton |
| These include anything that swims in the ocean | Nekton |
| These include the animals that live along the bottom of the ocean floor like sponges, coral, sea cucumbers, and crabs. | Benthos |
| What is the word that refers to the amount of salt in the water? | Salinity |
| What is the name of a wave caused by an underwater earthquake? | Tsunami |
| What is the up and down motion on the surface of the ocean? | Wave |
| What increases the deeper you go? | Water Pressure |
| What decreases the deeper you go? | The amount of light, the temperature, and the amount of animals |
| Give an example of a typical ocean flood chain. | (energy from the sun -->) phytoplankton, zooplankton, small fish, bigger fish, large ocean predator |
| Give examples of adaptations ocean animals have to survive | *Flashy colors to warn off predators they are dangerous *long, skinny bodies streamlined to swim faster *long noses to reach into cracks in rock or coral *octopus has a fake eye on its skin to scare predators |
| What part of the ocean floor is like an underwater mountain? | Mid-Ocean Ridge or Sea Mount |
| What is echolocation? | It is when animals send out sound waves and listen to it bounce back to gather information about their surroundings, including where their food is. |
