Chapter 13 Review
| Question | Answer |
|---|---|
| The continual movement of water from Earth's atmosphere to Earth's surface and back again. | water cycle |
| Narrow streams of water that break through sandbars and drain rapidly back to sea. | rip currents |
| A global weather event that may last for 12 to 18 months and is caused by changes in air and water movements. | El Nino |
| A mass of moving water. | current |
| The difference in height between high tide and the next low tide. | tidal range |
| A tidal bulge that is smaller than normal, resulting in less extreme high and low tides. | neap tides |
| The vertical movement of deep water up to the surface. | upwelling |
| A measure of the amount of matter packed into a unit of volume. | density |
| The periodic rising and falling of the water level of the ocean. | tide |
| An extra-high tidal bulge and an extra-low tidal dip that occurs at the time of the new Moon or full Moon. | spring tide |
| The movement of water parallel to the shore; occurs in places where the waves meet the land at an angle rather than head-on. | longshore current |
| A system that uses sound waves to measure distance and locate objects. | sonar |
| The amount of dissolved salt contained in water. | salinity |
| The sloping land that lies submerged around the edges of a continent. | continental shelf |
| This brings nutrients up from the bottom of the ocean to the surface. | upwelling |
| The gravity of the Sun and the gravity of the moon combine to pull of Earth's waters from the same direction, resulting in this. | spring tide |
| Because waves rarely meet the land exactly head-on, these occure along almost every shore. | longshore current |
| This is lower in areas where the ocean is diluted by fresh water. | salinity |
| During these years, weather patterns change around the planet. | El Nino |
| Ocean water contains | both dissolved solids and dissolved gases |
| Large amounts of rainfall would lower the | salinity of a shallow part of the ocean |
| In general, how does ocean temperature change with depth? | deep water is cooler than water at the surface. |
| What would be most useful to explore a deep and difficult-to-reach section of the mid-ocean ridge? | robots with camera |
| A surface current is set in motion by | the wind |
| A surface current moves cold water | away from the poles |
| Deep ocean currents slowly move water | along the bottom of Earth's oceans |
| An upwelling moves nutrients from the deeper waters to | the surface |
| The Gulf Stream moves ____________________ away from the poles to give Great Britian a mild climate. | warm water |
| Most ocean waves are the result of | the transfer of energy from the wind to the water below |
| Waves breaking along a shore are caused by an increase in their | wave height |
| A longshore current is the transfer of | energy parallel to the shore |
| What causes rip currents to form? | high winds and strong currents |
| Tides are caused by the gravitational pull of Earth and | Earth's waters on the Sun |
| The tidal bulge is smaller than normal during a | neap tide |
| The difference in height between a high tide and the next low tide is called the | tidal range |
| Electricity is generated by a tidal dam when | water flows through turbines during high tide |
| The salinity of a sample of ocean water is the water's | dissolved salts in the water |
| The amount of matter is a given volume of ocean water is the water's | density |
| Wind blowing across the ocean causes | surface currents to form |
| A mass of moving water is called a | current |
| El Nino is caused by changes in _____________ currents | surface |
| What happens whan an ocean wave breaks on the shore? | It loses energy |
| What causes a longshore current? | waves stricking the shore at an angle |
| What has the greatest effect on Earth's tides? | gravity |
| Tidal range is the difference in height between | one high tide and the next low tide |
| Tadal ranges are largest during a | spring tide |
| Salinity is the amount of dissolved | salt in water |
| The amount of matter in a unit volume is | density |
| A surface current near Earth's equator is set in motion by | global winds |
| Water waves are often a transfer of | energy from moving air |
| Rip currents flow at nearly _________________ to the shore | right angles |
| The moon has a greater effect on Earth's tides than the Sun because the moon is | closer to Earth than the Sun |
