Gravity explained in an easy to understand way.
Gravity
The attractive force between all objects that have mass. Gravity is the natural force that pulls objects toward each other, like how the Earth pulls us downward.
High-intertidal zone
A coastal area covered by the highest of the high tides, mostly exposed to air. high-intertidal zone. The high-intertidal zone is the part of the shore that gets covered by the sea only during the highest tides.
Intertidal zone explained in an easy to understand way.
Intertidal zone
The shoreline between high and low tide. Intertidal zone. The intertidal zone is the area where the ocean meets the land and is covered by seawater at high tide and exposed to air at low tide.
Longshore current explained in an easy to understand way.
Longshore current
a water current parallel to the shoreline. longshore current. A longshore current is a movement of water along the coast caused by waves hitting the shore at an angle.
Low-intertidal zone
A coastal area exposed to air at the lowest of low tides and is primarily marine in character. Low-intertidal zone. This zone is where the ocean meets the land and is mostly underwater, but it's exposed to air during the very lowest tides.
Mid-intertidal zone
A coastal area regularly exposed and submerged by average tides. Mid-intertidal zone. The mid-intertidal zone is where the ocean meets the land and is covered by water only part of the time due to the tides.
Mudflats
Coastal wetlands that form in intertidal areas. Mudflats. Mudflats are flat, muddy areas that form because of the deposits of silt and clay in coastal regions, often exposed during low tide.
Neap tide explained in an easy to understand way.
Neap tide
The tide with the smallest difference between high and low tide neap tide. Neap tide occurs when the gravitational forces of the moon and the sun are perpendicular to each other, resulting in weaker tidal forces.
Rip current explained in an easy to understand way.
Rip current
A swift current that flows from a sandbar to deeper water. Rip current. It is a strong, narrow flow of water that moves directly away from the shore, posing a danger to swimmers.
Splash zone
The area along coastline that is regularly splashed, but not submerged by ocean water. Splash zone. The splash zone is the part of the shore where ocean water frequently hits but doesn't stay underwater.
Spring tide explained in an easy to understand way.
Spring tide
A tide with the greatest range between high and low tides. spring tide. Spring tide occurs when the Earth, moon, and sun are aligned, causing higher high tides and lower low tides.
Surf zone
Area close to the shore, where ocean waves break. Surf zone. The surf zone is where ocean waves crash and foam as they reach the beach.
Tidal bore
A wave formed by an incoming tide funnelling into a river or narrow bay. Tidal bore. A tidal bore is a large wave that travels up a river or bay as the tide rises, pushing water upstream.
Tidal range
The difference in height between the high tide and low tide. Tidal range. Tidal range is the vertical difference between the ocean's surface at high tide and low tide.
Tide explained in an easy to understand way.
Tide
The daily rise and fall of the water level in the oceans. tide. Tides are caused by the gravitational pull of the moon and the sun on Earth's oceans.
