a system that uses sound waves to calculate the distance to an object.
continental shelf, the continental slope, the abyssal plan, and the mid-ocean ridge.
What would you see if you traveled along the ocean floor?
the gently sloping, shallow area of the ocean floor that extends outward from the edge of a continent.
the incline beyond the edge of the continental shelf.
the smooth, nearly flat region of the ocean floor.
a range of mountains that winds through the oceans.
a canyon in the ocean floor.
inter-tidal zone, neritic zone, pelagic zone, open ocean zone, benthic zone, and abyssal zone.
Name the ocean zones in order from surface to ocean floor?
inter- tidal zone
a zone that begins a high-tide and stretches out to the point exposed by the lowest low tide.
a zone that extends from the low-tide line out to the edge of the continental shelf.
a zone that includes the deepest, darkest part of the ocean.
the bottom zone of the ocean, which includes the ocean floor.
temperature and sunlight.
Which two things decrease as you go deeper in the ocean?
What happens to pressure as you go deeper in the ocean?
the movement of energy through a body of water.
when winds blowing across the water's surface transmit their energy to the water.
How do most waves form?
the horizontal distance between crests.
the number of waves that pass a point in a certain amount of time.
the vertical distance from the crest to the trough.
wave height increases and wavelength decreases.
What happens to wave height and wave length near the shore?
the movement of sand along the beach.
a rush of water that flows rapidly back to sea through a narrow opening.
by eroding the shore in some places and building it up in others.
How do waves shape a beach?
a method of reducing erosion of a beach by building a wall of rocks or concrete.
daily rise and fall of Earth's waters on its coastlines.
the interaction of Earth, the moon, and the sun.
What are tides caused by?
a tide with the greatest difference between the heights of high and low tide.
a tide with the least difference between low and high tide.
the total amount of dissolved salts in a sample of water.
a large stream of moving water that flows through the oceans.
Earth's rotation on the direction of winds and currents.
What causes surface currents?
the pattern of temperature and precipitation typical of an area over a long period of time.
a climate event that occurs every two to seven years in the Pacific Ocean, during which winds shift and push warm water toward the coast of South America.
the movement of cold water upward from the deep ocean.
tiny ocean organisms, minerals, and other nutrients from the deeper layers of the water.
What do upwellings bring "up"?
an underwater vehicle built of strong material to resist pressure.
detailed charting of the features of an area; heights, depths, and shapes of the surface of an area.
underwater, cone-shaped volcanic mountains.
the ocean floor at a depth of more than 4,000 meters.
