Land forms, continents, islands, etc,. all get in the way of currents

Heat capacity of water, it takes a long time to cool, so currents can be maintained

Salt concentration, where salt water is more dense, therefore it will sink

Tornadoes- the winds from them cause currents

Convection currents, where warm, less-dense water mover away from the equator and is replaced by deep, cold water

Fish swimming

Earth's rotation, west side of oceans have faster moving, narrower currents

Wind, prevailing winds push a lot of water and contribute to ocean currents

land near warmer ocean currents will be cold and dry

land near warmer ocean currents will be tropical and warm

land near cooler ocean currents will be dry and cold

land near cooler ocean currents will be warm and humid

pushes the subtropical jet stream farther north than usual

when the surface water and water levels are higher than usual

causes the water on the coast of Peru to become cooler

Indonesia and Australia receive more rain than usual

is a shift in ocean currents, water becomes warmer, and a shift in atmospheric conditions in the tropical Pacific ocean

a shift to cooler than average temperatures, in the tropical pacific ocean

is also caused by the increase in the surface temperatures of the coast of south america and the tropical pacific ocean

trade winds, warmer air and water, and storms cause higher water levels

causes extra water to be pushed to the east, going against the equatorial current, causing water to slosh around

causes rich nutrients on the coast of south america

summer jet stream above North America shifts north

is caused by the cycles of ocean currents, surface winds, and atmospheric pressures

summer jet stream above North America shifts North

Indonesia and Northern Australia receive more rain than usual

the cycles cause the water on the coast of Peru to become cooler

is a shift to cooler than average temperatures

is opposite to El Nino

The sun's energy is distributed unevenly throughout Earth's surface. Since the point that is facing the sun the most is the equator, that region is the warmest. The further north or south you are, the less sunlight there is hitting you. This causes it to usually be colder closer to the poles and warmer closer to the equator. Earth is tilted on a 23.5% angle. This causes the northern part of the earth to be tilted towards the sun for half of the year (while still rotating), and this is summer. The other half is facing the sun indirectly, so it is in winter. After 6 months, it has switched so that the seasons have changed. 3 months into the 6 month period is spring or fall.

This is the wrong answer

All of the sun's energy hits the equator directly, and heats the surrounding areas. Ocean currents pull this heat around the earth, and that is what heats the earth.

The sun is the driving force behind weather on Earth. The sun emits different types of electromagnetic radiation. This radiation travels by waves and does not need a medium. (ex. Sound needs a medium such as air, solids, liquids, etc. before it can be heard)

Climate refers to the weather conditions of an area averaged over a long period of time; weather refers to the conditions outside that vary from day to day

Climate refers to the conditions outside that vary from day to day; weather refers to the weather conditions of a particular area averaged over many years

How close you are to the north pole, the amount of solar energy being emitted, the earth's weight, and climate change.

The weather of one day in September averaged out over many years

The sun, the Earth's rotation, the distance an area is from the equator, the composition of the atmosphere, and major geographic features.

Nitrogen-78%, Oxygen-21%, others such as carbon dioxide, argon, helium, and more are found in the last 1%.

Nitrogen-21%, oxygen-78%, carbon dioxide, 1%

Equal parts oxygen and carbon dioxide

Most of earth (97.5%) is covered in freshwater, so there is not much of a worry about the scarcity of it. All of the saltwater is frozen, so we do not need to worry about accidentally drinking it.

Most of earth (97.5%) is covered in saltwater, the rest of it is freshwater. 87.3% of this freshwater is frozen in the form of glaciers, leaving only 12.7% for drinking. This means that of all the water in the atmosphere, only a tiny portion of this is available to drink. This is an issue for countries that have either begun to run out of freshwater, or those that do not have access to it.
