What are 3 types of ocean currents?
Two major kinds of currents define the planet’s oceans: surface currents driven by wind and deep-water currents driven by variations in seawater density.

What 3 things are ocean currents controlled by?
Surface currents are controlled by three factors: global winds, the Coriolis effect, and continental deflections. surface create surface currents in the ocean. Different winds cause currents to flow in different directions.
What are the 2 types of surface currents?
Local Surface Currents Two are longshore currents and rip currents.
Where is the ocean surface the highest?
The strongest and most renown surface ocean currents are the Gulf Stream, that travels from the Caribbean Sea, along the East coast of North America and across the Atlantic Ocean to Europe, and the Kuroshio Current in the North Pacific Ocean off the East coast of Asia.
What is the strongest current in the ocean?
Antarctic Circumpolar Current
Are the oceans flat?
Most people are surprised to learn that, just as the surface of the Earth is not flat, the surface of the ocean is not flat, and that the surface of the sea changes at different rates around the globe. You may have heard the term “global sea level,” which refers to the average height of all of the Earth’s ocean basins.
Where does most of the heat in ocean water come from?
sunlight
What would Earth be like if ocean water did not move?
If ocean currents were to stop, climate could change quite significantly, particularly in Europe and countries in the North Atlantic. In these countries, temperatures would drop, affecting humans as well as plants and animals. In turn, economies could also be affected, particularly those that involve agriculture.
Are Oceans Warming?
The International Panel on Climate Change (IPCC) Fifth Assessment Report estimates that the upper ocean (surface to 750 m deep) has warmed by 0.09 to 0.13 degrees C per decade over the past 40 years.
Why Earth’s surface does not get hotter and hotter?
The Earth does not continue to get hotter and hotter as it absorbs energy from the sun, because it gives off energy to space as invisible infrared radiation. The amount of infrared radiation energy the Earth gives off depends on its temperature.
Which part of the earth absorbs the most sunlight?
The sun’s rays strike Earth’s surface most directly at the equator. This focuses the rays on a small area. Because the rays hit more directly, the area is heated more.
What happens if the heat budget is out of balance?
If the imbalance is positive and more energy enters the system than exits, Earth grows warmer. If the imbalance is negative, the planet grows cooler.
What would happen if the Earth’s energy budget was not balanced?
If the Earth system is changed either through natural phenomena — such as volcanoes — or man’s activities and an imbalance in the Earth’s energy budget occurs, the Earth’s temperature will eventually increase or decrease in order to restore an energy balance.
What happens if Earth’s radiation budget becomes out of balance?
A budget that’s out of balance can cause the temperature of the atmosphere to increase or decrease and eventually affect our climate. The units of energy employed in measuring this incoming and outgoing radiation are watts per square meter (W/m2).
