In a hot air heating system, why is it better to put the vents that release heat near the floor rather than near the ceiling?
because heat rises and if the vents are on the ceiling the heat will just rise out of the room
water from precipitation flowing across land, rivers and oceans
when a liquid becomes a gas
the process by which plants release water vapor through their leaves
when water vapor cools and becomes a liquid
rain, snow, sleet, or hail falling from the clouds to the earth
when tiny ice particles collect water while moving up and down in a cloud
when temperature of clouds and air are above 32℉
rain from a warm cloud falls through freezing air
when a wind is colder than 32℉ contacts a cloud
the amount of water vapor in the air
the temperature air must cool to to become saturated
geosphere, hydrosphere, atmosphere, biosphere, cyrosphere
2 forms of fluids
liquid and gas
wind is created by differences in _____
hot air rises and creates areas of ____ pressure
air moves from ares of _____ pressure to areas of _____ pressure
wind does not blow in a straight line, it curves due to the...
rotation of the earth
the curving motion of objects
weather is caused by changes in...
humidity, pressure and temperature of the air in our atmosphere
energy transfer within a solid by direct contact
hand touching a hot frying pan
energy transfer within fluids from one place to another
earth redistributing heat through air currents
energy transfer in waves
radiator or mirages
the greenhouse effect
some radiant energy (heat) from the sun is reflected off the earth and "trapped" by the ozone layer and clouds, keeping the surface and lower levels of the troposphere warm.
