How old is the Earth?
4.6 Billion Years Old
What do you call the movement of air from areas of high to low pressure?
Wind
What are the three processes of the water cycle?
Evaporation, Condensation, Precipitation
What weather conditions are associated with a high-pressure system?
Clear skies and fair weather
Why can't you see the GPGP on Google Earth (or from space)?
Because it's made up of tiny pieces of plastic, called microplastics, that are too small to see from a satellite
Which planet in our solar system has the strongest gravity?
Jupiter
Direct sunlight at the equator heats air. Does this create an area of high or low pressure, and why!?
Low pressure, because warmer air expands, becomes less dense and rises.
Water changes state from gas to liquid during this process of the water cycle.
Condensation
What weather conditions are associated with a low-pressure system?
cloudy skies with a chance of precipitation
What phase is the moon in when the "light is on the right?"
Waxing (growing)
How many stars are in our solar system?
What 2 things drive the movement of global winds around the planet?
Earth's rotation and differences in temperature (also acceptable: the sun's energy and Coriolis effect
What 2 things drive the movement of water from Earth's surface to the atmosphere and back again?
Sun's energy and gravity
What might cause days of gentle snowfall and temperatures in the high teens to rise to the low 20s?
A warm front
What phase of the moon do we see when the Moon is directly in between the Earth and Sun?
New Moon
What are the 2 main reason the Earth experiences seasons?
Earth's revolution/orbit around the sun and the tilt of the Earth on it's axis
The rotation of the earth on its axis causes air to appear to move to the right in the Northern Hemisphere, affecting global wind patterns. What is this effect called?
The Coriolis Effect
What state change occurs during evaporation?
liquid to gas
What weather conditions are associated with a cold front?
severe storms followed by a drop in temperatures
What do we call the longest and shortest days of the year?
The solstices
What TWO factors affect the gravity between two objects?
mass & distance
What would happen to the planets in our solar system if the sun's gravity suddenly "disappeared" or "turned off"?
The planets would fly off (in straight lines) into space.
What drives the movement of ocean surface currents?
Global wind patterns
Name the planets in their correct order, beginning with the planet closest to the Sun.
Mercury - Venus - Earth - Mars - Jupiter - Saturn - Uranus - Neptune
Cold air molecules move slower and are more dense than warm air molecules.
