Earth Science Chapter 16 Test Oceans

Which statement best describes the temperature of the ocean's surface water?

• areas of high salinity have the coldest water

• areas close to the equator have the coldest water

• areas at high latitudes have the coldest water

• areas with a low density have the coldest water

When weather conditions are disrupted by El Nino, how does this affect ocean nutrients?

• Ocean upwelling decreases, resulting in lower levels of nutrient-rich water.

• Wind blows offshore. creating an increase in nutrient-rich water.

• Greater ocean circulation causes nutrients to be more equally distributed.

• Stronger storms prevent fishing, resulting in fish depleting the nutrient supply.

How do oceanographers define salinity?

• Number of grams of mineral salt per liter of water

• Number of grams of salt per kilogram of water

WHERE WOULD THE TEMP OF THE OCEAN'S SURFACE WATER BE THE LOWEST?

• areas close to the equator

• areas of high latitudes

How do water particles move in a wave?

• They move in a circular motion

• They move forward with the wave

• They move up and down

• They stay still

Which of the following are responsible for surface currents?

• temperature and salinity

• wind and density

• density and salinity

• wind and the earth's rotation

What weather would create the best surfing waves?

• Strong winds that blow for short periods of time with a short fetch

• Strong winds that have been blowing for a long time with a long fetch.

What forms as a result of the wind's frictional force on water?

• deep sea currents that move in a path similar to the wind currents

• surface currents that move in a path similar to the wind currents.

What weather would create the weakest surfing waves?

• Weak winds that blow for short periods of time with a short fetch

• Weak winds that blow for long periods of time with a long fetch

Which factors play a role in creating ocean waves?

• wind speed, direction, and duration

• wind speed, direction, duration, and fetch
