Why does the Northern Hemisphere have warm summers? 4 things.
Hint 1
Seasons are caused by a number of different factors. - answer The
Sun's rays hit the ground at a more perpendicular angle.
The Sun's energy is more concentrated.
Days are longer.
The north pole is tilted toward the Sun.
You go camping in Canada with a friend. You both go to bed when
the Sun goes down and get up when the Sun comes up, but you both
notice that you are not getting enough sleep! What time of year are
you most likely near?
The length of the day (and night) changes with the seasons. -

Condensation is a phase change from _______ to _______, which _______
the surrounding air.
Hint 1for Part A.
, Condensation is the opposite of evaporation. - answer gas; liquid;
warms
How is temperature defined?
Hint 1for Part A.
Temperature is used to describe how warm or cold an object is. -
answer a measure of the average kinetic energy of the atoms or
molecules in a substance
You are boiling a pot of water on an electric stove. The pot sits
directly on the heating coil and is primarily heated by _____.
Hint 1for Part A.
The pot is sitting directly on the heating coil so there is contact
between the heating coil and the pot. Which heat transfer
mechanism is most effective in this situation? - answer conduction
Conduction is the molecule-to-molecule transfer of heat from the
heating coil to the bottom of the pot.
The Sun is very hot, so it radiates _______ energy than Earth, and the
energy has a _______ wavelength than energy emitted from Earth.
Hint 1for Part A.
The sun primarily emits visible, ultraviolet, and infrared
electromagnetic radiation. - answer more; shorter
The Sun emits more energy than Earth, and hotter objects emit
shorter wavelength energy than cooler objects.
