Nuclear _____________________ light elements combine into heavy elements

_____________________ -transfer of heat through electromagnetic waves

Water has a higher heat capacity than land.

This means that some places on Earth receive more heat while others receive less heat.

the heat absorbed by the ocean is spread out over a greater volume and light can penetrate the surface of the water. The heat from the sun is dispersed over a greater depth.

oceans move energy around with their ___________.

The oceans lose a lot of heat from what?

the 23.5 degrees tilt of its rotation axis, its revolution around the Sun

If the Earth was tipped less, the seasons would be

Seasons are not caused by the ______________ of the Earth from the sun

If the Earth tipped over a few more degrees, the seasons would be

As the Earth moves in its orbit, the tilt of the North Pole changes, causing the _____________________.

Summer Solstice: First day is ~ _____________________. On this day the Earth's North Pole is tilted closest to the sun. This is the longest day of the year.

Fall (Autumnal) equinox:~_____________________

The northern hemisphere and the southern hemisphere have _____________________ seasons.

Winter Solstice: First day is ~ _____________________. On this day the Earths North Pole is tilted farthest from the Sun. This is the shortest day of the year.

What does solar energy plays a role in:

What occurs when the tilt is neither away from the Sun nor toward the Sun. It is between the two solstices.

Places close to the Equator do not experience very big seasonal changes. This is because they receive a more direct ____________ of sunlight all year long.

Spring (Vernal) equinox:~ _____________________

Solar energy also Provides chemical energy through _____________________

It is the process by which autotrophic organisms use solar energy to make sugar and oxygen gas from carbon dioxide and water.

able to make its own food

The basis of life of earth

Plants pull _____________________ from the atmosphere and use it to make food through photosynthesis.

This is formed from carbon

The magnetic field _____________________ the planet from harmful radiation.

The strength of the field is directly related to:

This difference is magnetic _____________________. The Earths magnetic north is changing every day because of the hot, liquid metal that surrounds the inner core.

This is the process of burning a substance, such as wood or fossil fuels.

The magnetic field traps the charged particles of the _____________________ pushing them up.

When electrons flow along the field lines to the poles they rain down energizing the molecules of the atmosphere making them glow causing the _____________________.

Earth’s magnetic field extends _____________________ the earth’s diameter outward from the earth.

Earths magnetic field also prevents _____________________ of the atmosphere.
