1The region of the ocean floor made of continental crust is called the [blank_start]continental margin[blank_end]
- Acontinental margin
2The region of the ocean floor made of oceanic crust; the floor of the deep ocean between the continental margin and the mid-ocean ridge is called the [blank_start]deep ocean basin[blank_end]
- Adeep ocean basin
3The shallow part of the ocean at the edge of the continental shelf between the shoreline and the continental slope (up to 200 m deep) is called the [blank_start]continental shelf[blank_end]
- Acontinental shelf
4The region of the continental shelf that extends steeply downward to ocean floor between the continental shelf and continental rise (200 m-4,000 m deep) is called the [blank_start]continental slope[blank_end]
- Acontinental slope
5The base of the continental slope made of large piles of sediment; the boundary between the continental margin and the deep-ocean basin is called the [blank_start]continental rise[blank_end]
- Acontinental rise
6Underwater mountain ranges that form where tectonic plates pull apart, allowing magma to rise up, are called [blank_start]mid-ocean ridges[blank_end]
- Amid-ocean ridges
7A long, narrow valley between the ridge and the rift zone that forms as tectonic plates separate at a continental divergent boundary is called a [blank_start]rift valley[blank_end]
- Arift valley
8An underwater mountain on the ocean floor at least 1,000 m high of volcanic origin is called a [blank_start]seamount[blank_end]
- Aseamount
9A steep trench in the deep-sea floor that runs parallel to a chain of volcanic islands or a continental margin is called an [blank_start]ocean trench[blank_end]
- Aocean trench
10[blank_start]Salinity[blank_end] is a measure of the amount of dissolved salts in a given amount of liquid; usually measured in grams of solutes per kilogram of water
- ASalinity
11The [blank_start]water cycle[blank_end] is the continuous movement of water from the ocean to the atmosphere (evaporation) to the land (condensation and then precipitation) and back to the ocean (through condensation, precipitation and run-off)
- Awater cycle
12[blank_start]Sonar[blank_end] is short for "sound navigation and ranging. " It determines the distance of an object under water using echolocation
- ASonar
13The [blank_start]thermocline[blank_end] is a layer in a body of water in which water temperature drops with increased depth faster than it does in other layers
- Athermocline
14The top of a wave is called a [blank_start]crest[blank_end]
- Acrest
15The bottom of a wave is called a [blank_start]trough[blank_end]
- Atrough
16[blank_start]Wave length[blank_end] is the horizontal distance between two successive crests or troughs
- AWave length
17[blank_start]Wave height[blank_end] is the height of the wave from the wave crest to the wave trough
- AWave height
18[blank_start]Wave frequency[blank_end] is the number of wave crests passing a set point each second
- AWave frequency
19[blank_start]Wave period[blank_end] is the time required for the wave crest at a set point to reach a second set point
- AWave period
20A [blank_start]tsunami[blank_end] is a giant wave caused by an earthquake on the ocean floor
- Atsunami
21A [blank_start]wave[blank_end] is any disturbance that transfers energy through matter or empty space
- Awave
22A [blank_start]mechanical wave[blank_end] is a wave that requires a medium through which to travel
- Amechanical wave
23An [blank_start]ocean current[blank_end] is a movement of ocean water that follows a regular pattern
- Aocean current
24A [blank_start]surface current[blank_end] is a horizontal movement of ocean water that is caused by wind and that occurs at or near the ocean's surface.
- Asurface current
25[blank_start]Deep ocean currents[blank_end] are movements of water like a river in the middle of ocean water (caused by differences in density)
- ADeep ocean currents
26The [blank_start]Coriolis effect[blank_end] is the apparent curving path of a moving objects from an otherwise straight path due to Earth's rotation
- ACoriolis effect
27[blank_start]Upwelling[blank_end] is the movement of deep cold and nutrient rich water to the surface
- AUpwelling
28A [blank_start]convection current[blank_end] is a current that the sun heats from near the equator and near the poles
- Aconvection current
29[blank_start]Salinity and temperature[blank_end] cause differences in density
- ASalinity and temperature
30The broad, flat part of the deep-ocean basin covered with the remains of tiny marine organisms, average depth is around 4,000 m is called the [blank_start]abyssal plains[blank_end]
- Aabyssal plains
