Science Water Cycle + Energy Test
| Question | Answer |
|---|---|
| Kinetic | energy in motion, bowling ball hitting over a bowling pin |
| Potential | stored energy held in readiness, rubber band stretched in your hand |
| Mechanical | associated with physical motion/movement , car moving, frog leaping through air |
| Chemical | stored in chemical bonds that holds chemical compounds together, stored in foods |
| Electric | moving electric charges, energy in power lines |
| Electromagnetic | travels in waves (light energy) , U.V. light from sun |
| Nuclear | stored in nucleus of an atom, nuclear power plants |
| Thermal | energy of moving particles in an object- particles move faster, thermal E increases- ice cream melting |
| Toaster | Toaster-sun-air-windmill-toaster, sun-water-dam-toaster |
| Stereo | Stereo – sun- air-windmill- stereo sun-water-dam-stereo |
| Lamp | Lamp- sun-solar panel- lamp sun-corn-ethanol plant-lamp |
| Condensation | thermal energy decreases as gas turns into liquid in a cloud |
| Evaporation | thermal energy increases as liquid turns into a gas (particles moving faster) |
| Precipitation | thermal energy stays fairly consistent (can change depending on atmosphere temperature) |
| Solid | thermal energy is the least particles moving slowest |
| Liquid | hermal energy is mediocre- particles moving in-between a gas and solid state |
| Gas | thermal energy is the most- particles moving the fastest |
| Collection | thermal energy stays fairly consistent (water closer to equator will increase in thermal energy faster) |
| Two types of currents and what drives them | Surface currents driven by wind, Deep currents driven by density (temp. and salinity) |
| Things that can affect ocean currents | Wind, Density, Temperature, El Nino, and The Coriolis Effect |
| The Gulf Stream | Gulf Stream driven by powerful westward winds,starts in the Gulf of Mexico travels toward the Caribbean up the northeast coast of the U.S. and up toward Northern Europe.Effects the climate in the areas it is near as well as organisms and ship speeds using |
| El Nino | affects can last up to two years, it can occur every 2 to 7 years, heavy rains, flooding, mudslides and tornados are all associated with El Nino |
| The Coriolis Effect | rotation of the Earth and how it effects the movement of the ocean currents, it turns the Northern hemisphere currents to the right and southern hemisphere to the left |
| The Coriolis Effect Part 2 | Why certain parts of the world have warmer water than others- closer to the equator hit more directly by the sun absorb more thermal energy as opposed to the water closer to the poles. |
| The Coriolis Effect Part 3 | In addition, certain currents such as Gulf Stream can affect water temperatures of places that would expect to have cold water, but instead have warm because of the Gulf quickly moving warm water in that direction. |
| Upwelling | the mixing of cold and warm water- deep water from below comes to the surface and surface water becomes part of the deep water |
| Upwelling Part 2 | – helpful because brings up organisms, minerals, and nutrients that other surface life is depending on to maintain a healthy diet. It is a food chain reaction to keep all organisms alive and satisfied. |
| Circular Patterns within the currents | patterns are caused by the Coriolis effect as well as the continents being in the way of the natural flow of the currents. |
| Circular Patterns within the currents Part 2 | The surface currents are directed by the wind and when pushed near a continent they can pushed back in the other direction creating a circular pattern |
| Density | can affect the deep currents in the ocean, more dense things are more likely to sink than less dense things- cold water is more dense than warm water, salt water is more dense than fresh water. |
| Water Cycle | thermal energy from the sun and mechanical energy from the wind increases the rate of evaporation, which drives the whole cycle. After water evaporates it cools in the atmosphere and losing thermal energy to become a |
| Water Cycle Part 2 | cloud which eventually precipitates into a collection basin. This collection basin can be heated again by the sun’s thermal energy or sped up by the wind’s mechanical energy to start the whole process again. |
