Gravity Basics
What is anything that has this property also has its own gravitational pull.
Mass
This celestial body forms the deepest gravity well in our solar system.
The Sun
This tide occurs when the Sun, Earth, and Moon are aligned in a straight line.
Spring Tide
This is the number of high tides most coastal areas experience in a single day.
2
This term describes the point where the Moon is closest to Earth.
Perigee
These are the two primary factors that determine how strong a gravitational pull is
Mass and distance
According to Einstein's discovery, mass bends space to form this.
A gravitational well
This tide occurs when the Sun and Moon are at a 90-degree angle relative to Earth.
Neap Tide
This is the reason the Moon has a stronger pull on our tides than the much larger Sun.
It is much closer to Earth
This term describes the point where the Moon is farthest from Earth.
Apogee
This is the force of attraction between any two objects.
Gravity
This term describes a solar system model where the Sun is at the center.
Heliocentric
These are the two moon phases you will see during a Spring Tide.
New Moon and Full Moon
This is the reason there is a tidal bulge on the side of Earth opposite the Moon.
Inertia
This is why we experience greater tidal bulges during Perihelion.
The Sun is closer to the Earth
If you increase the distance between two objects, the gravitational pull does this.
It decreases
This is why the Sun has a deeper gravity well than the Earth or Moon.
It is much more massive
These are the two moon phases you will see during a Neap Tide
First Quarter and Third Quarter
Tides change throughout the day because of this specific movement of Earth.
Rotation
This is the point in orbit where Earth is farthest from the Sun.
Aphelion
While the Earth is pulling you toward it, you are doing this to the Earth.
Pulling back with your own gravity
This is the specific reason planets orbit the Sun rather than drifting away.
The Sun’s massive gravitational pull (deepest well)
Describe the high tide level during a Neap tide.
It is at its lowest level
If a high tide occurs at 12:00 PM (noon), the next low tide will occur at roughly this time.
6:00 PM
What is the definition of "Tidal Range."
The difference between high tide and low tide
