Tides
How many high tides are there in a day
2 High Tides
How many Low tides are there in a day
2 Low tides
How many tidal bulges are around Earth.
2 Tidal Bulges
The force of attraction between all objects in the universe. This is only important when at least one of the objects is very large, like the Earth, Sun, or Moon.
Gravity
The maximum height reached by a rising tide.
High Tide
The minimum height of a falling tide
Low tide
A tide with a relatively small difference between high and low tide. This occurs when the Sun, Moon, and Earth form a right angle.
Neap Tide
The gravity of the Sun and Moon pull Earth's surface at right angles.
Neap Tide
What kind of tide would you expect during a half moon?
Neap Tide
What happens on the side of Earth opposite the Moon?
Since the Earth rotates, the opposite side of the Moon is tilted towards the Moon. So as a result, the Moon's gravity causes the oceans farther away from the Moon to pull outwards towards the Moon, creating another tidal bulge.
A tide with a relatively large difference between high and low tide. Occur when the Sun, Moon, and Earth are aligned (in a line).
Spring Tide
The gravity of the Sun and Moon pull Earth's surface in opposite directions.
Spring Tide
The gravity of the Sun and Moon pull Earth's surface in the same direction.
Spring Tide
What kind of tide would you expect during a full Moon?
Spring Tide
What kind of tide would you expect during a new Moon?
Spring Tide
What causes the tidal bulges to form
Sun and Moon's gravitational pull on Earth
How does the moon's gravity affect the ocean nearest to the Moon?
The Moon's gravity causes the oceans nearest to the Moon to pull outwards towards the Moon, creating a tidal bulge.
A bulge of water formed by the pull of the Sun and Moon's gravity. There are two of these. One is located on the side of Earth that faces the Moon. The other is on the opposite side of Earth, away from the Moon.
Tidal bulge
The regular rise and fall of ocean surfaces. Are caused by the gravitational pull of the Moon and Sun.
