Forms of Energy
Energy in motion
Kinetic Energy
what type of energy is also known as heat energy?
thermal energy
what do the arrows represent in a food chain/web?
flow of energy
What is one thing that affects the direction of ocean currents?
density, continental deflection, Coriolis effect, wind
What does a barometer measure?
air pressure
A bow and arrow when it is stretched has what type of energy... be specific!
elastic potential energy
heat transfer through direct contact
conduction
What is the first organism in any food chain?
a producer
What drives ocean currents?
density (temperature/salinity)
what type of weather occurs with high pressure systems?
good weather, clear skies, sunny
A plant uses sunlight to make its own food. What type of energy transformation is occurring in this process? Include 2 forms of energy
solar/radiant/light -> chemical
heat transfer through waves
radiation
producer, herbivore, carnivore, decomposer
The Gulf Stream is a warm ocean current. How does the Gulf Stream affect the climate of the regions it passes?
makes them warmer
A cold front moves into an area, what type of weather is most likely to follow?
heavy rain, storms, cold temps
When the mass of an object is doubles, what happens to its kinetic energy?
KE doubles
what type of heat transfer is responsible for explaining why a metal spoon gets hot after sitting in a bowl of soup?
conduction
Grass → Grasshopper → Frog → Snake → Hawk
What would happen to the grasshopper population if the frog population decreased significantly?
grasshoppers would increase
What is climate?
Hint: what 2 things determine climate?
The average temperature and precipitation an area receives over a long period of time
What is the name of an air mass that is dry and cold?
continental polar
when the speed of an object doubles, what happens to its KE?
it quadruples
convection
What does it mean to have a high biodiversity?
high variety of organisms- many different plants and animals living in an ecosystem
Describe the relationship between latitude and temperature.
high latitude = cold temp
low latitude = warm temp
renewable- hydroelectricity (water), wind, solar
nonrenewable- fossil fuels, natural gas, coal
