What is an ellipse?
an oval with two focal points, the true shape of the orbits in our solar system
Define alignment
The correct positioning of something
What happens to gravitational pull as the distance between two objects increases.
Gravitational pull decreases
What is the reference line for latitude?
Equator, it specifies a North or south position
What is the reference line for longitude?
Prime meridian, specifies position East or west
True or False
Moon phrases are caused by the change in the eccentricity at which we see the lit portion of the moon.
False
Moon phrases are caused by the change in the angle at which we see the lit portion of the moon.
Describe the alignment of the sun, moon, and earth during Neap tides.
Neap Tides: sun moon and earth are at right angles
low high tides and high low tides
Duration of insolation is how long we get hear or daylight.
What are the incoming solar radiation waves called?
ultraviolet
What direction does Earth rotate?
counterclockwise
What is earth's natural satellite?
moon
True or False
Heat and energy move in the same way.
False
Heat and energy move in different ways.
What evidence support's Earth's rotation?
1. Coriolis Effect
2. Foucault's pendulum
3. Day and night
What types of surfaces absorb UV rays?
Dark and rough
True or False
The equator has seasons
False
No seasons, always 12 hours of daylight
True or False
Tides are cyclic and predictable.
True
What is saturation?
The air is completely filled with water vapor. This is relative humidity of 100%
What causes seasons?
(2)
Seasons are caused by the tilt of the Earth's axis and its revolution around the sun.
Provide an example of a greenhouse gas
Carbon Dioxide, Carbon, Nitrous Oxide, etc.
True or False
Heat and energy move in different ways.
True
What is relative humidity?
a measure of how much moisture is in the air compared to how much it can hold
What is the dew point temperature?
The temperature at which the air will become saturated and condensation occurs.
How does moisture enter the atmosphere?
evaporation, transpiration
As the angle on insolation increases, the intensity of insolation increases.
What does this explain?
The angle of insolation increases until noon, then decreases. The angle in December vs. June impacts insolation.
True or False
Energy moves from hot to cold.
True
