DDES Global Patterns
Energy, Water Cycle, Ocean Currents
| Question | Answer |
|---|---|
| the ability to do work or cause change | energy |
| the transfer of energy | work |
| the energy of motion | kinetic energy |
| an example of kinetic energy | a bowling ball knocking over bowling pins |
| energy that is stored or held in readiness | potential energy |
| an example of potential energy | a stretched rubber band |
| some examples of mechanical energy | a frog leaping, wind blowing, a person doing jumping jacks |
| the source of thermal energy that causes evaporation | sun |
| the forms of energy that drive the water cycle | thermal and mechanical |
| thermal energy is at its LOWEST POINT during this process of the water cycle | condensation |
| thermal energy is at its HIGHEST POINT during this process of the water cycle | evaporation |
| the state of matter that has the HIGHEST amount of thermal energy | gas |
| according to the evaporation experiment we did in class, the factors that increased the rate of evaporation were.... | thermal and mechanical energy |
| the ideal conditions for wet clothes to dry on a clothesline | sunny & windy |
| a large stream of moving water that flows through an ocean | current |
| 1 type of current driven mainly by winds | surface currents |
| 1 type of current driven by the density of water | deep currents |
| an abnormal climate event that can affect ocean currents | El Nino |
| the saltiness and temperature that can affect ocean currents | density |
| when thermal energy affects ocean currents | temperature/sun |
| when mechanical energy affects ocean currents | wind |
| 2 factors that affect how dense water becomes | temperature and salinity(saltiness) |
| the effect of the earth's rotation on the direction of the winds and currents | the Coriolis Effect |
| the largest and most powerful surface current caused by strong winds from the west | the Gulf Stream |
| which is denser? fresh or salt water | salt water |
| which is denser? warm or cold water | cold water |
| the two jobs deep currents have are to mix and move water around the world and to carry cold water from.... | the poles back toward the equator |
| factors that cause there to be warmer parts of the ocean in some parts of the world than in others | the sun hitting the equator at a direct angle, the Gulf Stream bringing warm water, and thermal energy from the sun is absorbed into the water |
| some results of water upwelling(cold and warm water moving and mixing) | seabirds have enough fish to eat, fish have enough nutrients, and climate and weather differences |
| El Nino can affect the winds and currents around the world for this period of time | a couple of years |
| how often El Nino can happen | every 2-7 years |
| some types of weather events that occur during El Nino include | heavy rains, flooding, mud slides, tornadoes |
