air
the term that means the amount of moisture in the air
humidity (relative humidity)
the heating of an object by direct contact is called
conduction
heat from the sun that comes to Earth without touching is called
radiation
Atlantic ocean
what symbol is used on a weather map to represent a warm front. (symbol and color)
red half circles
warm air is _______ dense than cold air
less
if there are clouds or dust in the sky during the day- the temperature is cooler....why?
the clouds block the heat from the sun from reaching the Earth
Air masses that are dry and cold are called
continental polar
In general- on the coast- which is warmer- California or Florida?
Florida
how many paths are there is a series circuit for electrons to flow?
one
both sand and water are in the sunlight for the same amount of time....compare the temperature.
the sand will be ________ than the water
warmer
local winds are caused by
unequal heating of the Earth's surface OR differences in air pressure
air masses that are dry and warm are called
continental tropical
why do hurricanes in the norther hemisphere spin counter clockwise?
because the spinning of the Earth causes that motion. (water in drains also spins counter clockwise)
why are parallel circuits used for Christmas lights?
there are more that one path for electrons to flow- if one bulb goes out...the whole string is still working
why can warm air hold more moisture than cold air?
the air molecules are farther apart- so there is room for the water to fit in between the air molecules
global winds
What kind of weather is usually associated with a cold front? (draw a diagram of a cold front)
storms, temperature drops suddenly, winds, rain, snow
Why did the Nike shoes wash up on so many different beaches?
because the ocean currents moved them around in a large circular pattern
in a lightning storm- which statement is correct?
the protons from the ground move to the clouds
the protons from the clouds move to the ground
the electrons from the clouds move to the ground
the electrons from the clouds move to the ground
the % of oxygen in the air decreases with altitude
false.
the air pressure decreases, but the % of oxygen stays the same
During the day- if I stand facing the ocean my hair blows back. What is this type of breeze called? and how does it work?
sea breeze- air rises off the sand (warm air rises) and the cooler air above the water blows toward the shore
explain how hail is formed
cloud decreases in temp and water droplets start to fall out, but gets blown back up- collects a layer of ice, drops, gets blown back up collecting another layer until it is too heavy to stay in the cloud.
Why was there a record number of hurricanes last year (and more powerful) compared to 20 years ago?
the water temp is at a record high
why can you get MORE sunburned skiing than sitting on the beach?
the snow reflects the sun's light, sand absorbs the sun's light (heat)
