_________________ is How much solar radiation is reflected off of a surface
albedo
Thermal energy moves from areas of ________________ temperature to areas of ______________________ temperature
higher
lower
Why are areas near the equator generally warmer than areas near the poles?
Sunlight strikes Earth's surface at a higher angle near the equator
________________________ is The amount of thermal energy needed to raise the temperature of 1 kg of a material by 1°C
specific heat
snow and ice
____________________________ occurs through the transfer of thermal energy between materials by the collisions of particles

higher
Why does a black asphalt-covered parking lot get hotter on a summer day than a grass-covered area next to it?
Dark colors absorb more solar radiation than light colors
In what direction does thermal energy always move during conduction?

Water
Black Asphalt
Snow
Grass
Black Asphalt
How does thermal energy from the Sun get to Earth?
Through radiation through the vacuun of space
If you are in an area directly at the equator, what is your latitude?
