Waves
Most waves in the ocean are caused by this.
What is wind?
These are responsible for creating unique and important ecosystems on the intertidal shorelines.
While waves can break down coasts, they can also build them up through the process of this.
What is deposition?
This area of the intertidal zone during high tide is covered by water, but spends long periods of time exposed to the sun, air, and crashing waves in between those high tides.
What is the high intertidal zone?
This is the day to day changes in the air at one location.
What is weather?
A wave moving toward shoreline that begins to lean inward toward the land as the crest is moving faster than the base. Sooner or later, the crest falls forward, and this is formed.
What is a breaker?
The daily tides differ from place to place--they are not even all the way around the world. True or false
What is true?
This is the edge of the land. It is where the land and the sea come together
What is coast?
Many natural defenses against mighty waves can be found along a coastline which are these (name 3)
What are reefs, kelp forests, mangrove forests, and seagrass meadows?
Earth is surrounded by a thick layer of gases called this.
What is atmosphere?
A _____ is actually the energy moving through the water--not the water itself
What is a wave?
These are the regular rising and falling of the water levels of the ocean
What are tides?
Compression, hydraulic action, attrition, and abrasion are four types of this.
What is erosion?
These are formed in more protected areas, like the bays sheltered by headlands (for example), waves deposit these rocks and sediments.
What are beaches?
These are the four parts of a map
What are compass rose, scale, key and grids?
This is the water that pushes up the beach after a wave has broken on the shore.
What is a swash?
These factors cause tides (2 things)
What are the gravitational pull of our planet, our moon, and the sun?
These are narrow strips of land that jut out into the sea.
What are headlands?
This forms dunes by carrying sand up the beach, away from the waves, and depositing it where it will accumulate, often with help from anchored grasses and plants
What is wind?
This is the line drawn around the earth equally distant from both poles, dividing the earth into northern and southern hemispheres
What is the equator?
Different factors determine the amount of energy transferred from the wind's push to the water, including these...(name two)
What is the duration of the wind, how large or small the area is that the wind is happening over, and how strong the wind is blowing.
When the sun and moon are in alignment, the sun enhances the moon's gravitational pull. This creates an abnormally high "high tide" and an abnormally low "low tide." These are called this.
What are spring tides? (happen during full moons or new moons)
These can form on headlands when twin caves on either side of a headland are worn through to one another, or when a single cave is carved beyond its hardest rock layer, exposing a softer rock layer, easily broken through by the waves
What are arches?
This is the area of the seashore that is above the water level at low tide and under the water at high tide
What is the intertidal zone?
These are the important lines of latitude that define the part of the earth that has a warm, tropical climate. (2 answers)
What are the Tropic of Capricorn and the Tropic of Cancer?
