Why is upwelling important?

Upwelling provides nutrient rich water that sustains life

Upwelling regulates ocean temperature

Upwelling helps sailors to navigate the seas

The salt content of a substance

The Pepper content of a substance

The circulation of hot and cold matter

the weather pattern of a region

________ and _______ affect the ocean's density and cause the Global Conveyor Belt to travel

gravity and the Coriolis Effect

temperature and the Coriolis Effect

The Earth's oceans are generally warmer near the equator and cooler near the poles. Currents in the water near the surface circulate the water. Some of these currents are shown in the image below. Warm currents are shown in red. Cool currents are shown in blue. Which of the following best describes what the pictured currents do?

carry warm water away from the equator

carry warm water away from the poles

carry cool water toward the poles

carry warm water toward the equator

Warm air and water both tend to rise while cooler air and water sink. When different parts of the oceans are heated unevenly, this causes the water to

mix together in the water cycle.

A process known as upwelling often occurs along ocean coasts. In this process, warm water at the surface is driven out to sea by blowing winds. As the warm water moves out to sea, what most likely happens to the cold water beneath it?

It rises to the surface to replace the warm water.

It sinks closer to the ocean floor.

It is driven out to sea by the warm water.

The currents of the Earth's oceans are caused by

global winds and differences in temperature and salinity.

marine organisms and volcanic eruptions.

waves and earthquakes along tectonic plate boundaries.

disturbances by submarines and large ships.

Ocean currents affect temperatures on land.

The ocean has no effect on the temperature on the land.

All ocean water is the same temperature.

Ocean water does not move between locations.

Water in ocean currents can descend when it becomes colder and saltier than the surrounding water. If water descends to the bottom of the ocean, then other water must rise to the top. What causes water to rise to the top of the ocean?

It becomes less dense than the surrounding water.

It is forced upward by underwater mountain ranges.

It is brought upward by organisms that live in the ocean.

It cools down and dissolves additional salt.

The image below shows a system of ocean currents that are sometimes referred to as the global ocean conveyor belt. These currents are a form of convection in the ocean. What is one effect of this convection?

Water continually circulates throughout Earth's oceans.

Warm water on the ocean's surface stays on the surface.

The ocean constantly becomes colder as warm water is cooled.

Water from the ocean cools the atmosphere.

The image shows part of an ocean current in the Atlantic Ocean. The blue line represents the motion of deep, cool water. The red line represents the motion of warm surface water. One factor that affects ocean currents is the concentration of salt in the water. How can the saltiness of the water cause the surface water to sink, as shown above?

When some of the surface water freezes, the remaining water becomes saltier.

When ice melts, it makes the surface water more salty.

When cold water rises to the surface, it loses salt.

When the surface water is heated by the Sun, it dissolves more salt.

The image shows part of an ocean current in the Pacific Ocean. The blue line represents the motion of deep, cool water. The red line represents the motion of warm surface water. What most likely causes the current to behave as shown in the image?

When the water is heated, it becomes less dense and rises.

When the surface water is heated by the Sun, it becomes denser.

When the deep water is cooled, it loses energy and becomes denser.

When the cold water evaporates, less dense water rises to take its place.

Cold water near the ocean floor often flows in deep-water currents. The cold water flows toward the deepest regions of the ocean because

it is more dense than the warm water above it.

the water above it contains less algae.

it is warmer than the cold water above it.

the water above it is frozen in icebergs.

Currents caused by differences in water density are most often the result of

differences in temperature and salinity.

differences in salinity and wind.

uniform temperature and salinity.
