Segments in this Video

Atmosphere (05:16)


The Earth's atmosphere is a sphere of gas enveloping the planet which protects it from the harmful rays of the sun but also allows enough solar energy to warm it. The four layers of the atmosphere are the thermosphere, mesosphere, stratosphere, and troposphere.

Oceans (02:32)

Seventy percent of the Earth's surface is covered with water which is mostly contained in saltwater oceans; different areas of the oceans have varying levels of salinity. Earth's oceans regulate its climate by absorbing and releasing solar energy generated by the sun.

Ocean Currents (05:32)

Oceans distribute warmth throughout the planet after absorbing solar energy through the movement of their currents. The Gulf Stream is a current pulled warm air from the Southern U.S. to the British Isles.

Convection in the Atmosphere and Oceans (03:19)

Wind and ocean currents are responsible for distributing energy from the sun around the globe through convection loops.

Weather and Climate (01:28)

Weather is a condition of the atmosphere at a particular place and time, but climate is the general type of weather in a particular place throughout time.

Weather (04:31)

Weather is what is happening in the skies at a specific time and place; weather includes information like the temperature, humidity levels, precipitation, and wind. Extreme weather is caused when hot and cold air collide in Earth's atmosphere.

Climate (07:06)

The average weather condition in an area over a long period is climate which is caused by factors like ocean currents and winds. The three major climate regions are the temperate, tropical, and polar zones.

Earth has got swirl. The air in the atmosphere swirls. The water in the ocean swirls. But what does it all have to do with weather and climate? To answer this, we’ll have to get a close-up on all that swirl. Don’t worry, being dizzy is fun! Topics include: Earth's Place in the Universe; Investigating Earth's Past; Restless Earth; Mountains, Volcanoes, and Earthquakes; Energetic Earth; Atmosphere and Oceans; and Earth Systems.
