Answer:
C) Increases the pressure
Explanation:
Increasing the pressure might result in the change of temperature of the substance, which would change its state of matter.
The Lithosphere ("rock sphere") is the ground you are standing on and the whole inside of Earth.
The Hydrosphere ("water sphere") includes all of the rivers, lakes and oceans of Earth.
The Cryosphere ("icy cold sphere") is the frozen part of Earth: the glaciers, icebergs at sea, and the huge icecaps in Greenland and Antarctica.
The Biosphere ("Life sphere") includes all living things: the trees in the park, the birds in the air, the fly on your wall, the viruses that make you sick, your pets, and even you and all your friends!
The Atmosphere ("Air Sphere") is the envelope of air that surrounds the whole Earth.
The Exo- or Celestial Sphere ("Outside or heavenly sphere") includes the whole universe beyond the top of the atmosphere--the Sun, Moon, and stars, as well as the asteroids and the little bits of dust that make meteors when they hit the atmosphere.
Answer:
hot air rises because gases expand as they heat up.When air heats up and expands,its density also increases.The warmer,less dense air effectively floats on top of the colder, dense air below it. This creates a buoyant force that causes warmer air to rise.
cold air sinks because it is heavier as its more dense ( because of closely packed molecules) soits harder for them to move and they absorb less energy. Also, gravity pulls on it more strongly.
Hope it helps :)
No the sun is the biggest star in the universe.
