Answer:
<u>Geocentric Model</u>: - this model is Earth Centered
-Retrograde motion is explained by epicycles
<u>Heliocentric Model</u>: - This model is Sun Centered
-Retrograde motion is explained by the orbital speeds of planets
<u>Both models</u>:- Epicycles and deferents help explain planetary motion
-Planets move in circular orbits and with uniform motion
-The brightness of a planet increases when the planet is closest to Earth
Explanation:
Retrograde motion is an apparent change in the movement of the planet through the sky. Ptolemy's model of the solar systems was geocentric, where the Sun, Moon, planets and start all orbit the Earth in perfectly circular orbits. However this perfectly circular orbits around the Earth did not explain the occasional retrograde motion of the planets. In the Copernicus' heliocentric model, retrograde motion of planets is naturally explained. The explanation for retrograde motion in a heliocentric model is that retrograde occurs roughly when a faster moving planet catches up to and passes a slower moving planet.

may be 1 is the answer may be ..
The state of Vermont is known as green mountain state.
Answer:
An avalanche can be caused by vibrations from an earthquake or in severe conditions loud sounds can disrupt the snow.
GLOF is where a body of water contained by a glacier melts or overflows the glacier.
Explanation:
Avalanches occur in mountainous regions with a thick snow cover while a landslide occurs in sloppy places with loose and muddy soil. ... An avalanche is the movement of large snow volumes. An avalanche can be caused by vibrations from an earthquake or in severe conditions loud sounds can disrupt the snow.
