Standard 1.1.4: How the Earth uses Sun's Energy.

Where did the materials used to create planets in our solar system come from?

• Clumps of rocky material between the stars

• The same cloud of gas as our sun

• They flung out of our young sun

• They weren't created

When the north end of Earth's axis is tilted toward the sun, North America will experience:

• More indirect rays and longer days

• More indirect rays and shorter days

• More direct rays and longer days

• More direct rays and shorter days

Identify the nuclear reaction that fuses hydrogen gas to form helium and produces most of the Sun's energy:

• Friction

• Fusion

• Fission

• Gravity

Which BEST describes how energy from the Sun helps to maintain life on Earth?

• It heats Earth's atmosphere and surface, which helps stabilize temperatures on Earth and creates environments more favorable for life to exist.

• If forms the ocean's water and the oxygen in the atmosphere that organisms need for life functions.

• It prevents the destruction of the magnetic field around Earth that protects all life forms.

• It is absorbed by Earth's mantle, which drives plate tectonics to form new land masses for organisms to live

The Diagram shows the tilt of Earth and the angle of arriving sunlight caused by this tilt.

• The equator has the greatest number of deserts.

• The Northern Hemisphere is experiencing daytime.

• The tilt of Earth is causing icebergs to melt.

• The Southern Hemisphere is experiencing summer

Earth's spherical shape results in an uneven distribution of sunlight reaching Earths surface. This uneven distribution is most directly responsible for differences in which climatic variable at different latitudes on Earths surface?

• wind speed

• temperature

• annual rainfall

• average humidity

Which atmospheric phenomena are created by the interaction of charged particles with Earth's magnetosphere?

• Auroras

• Tornadoes

• rainbows

• inversions

Earth's magnetosphere is not uniformly shaped. It is compressed on the side facing the Sun and has a long tail extending away from the Sun. Which phenomenon is responsible for this shape?

• centripetal force of Earth's rotation

• gravitational attraction between Earth and the Sun

• solar winds bringing high-energy particles toward Earth

• differences in the distance between Earth and the Sun during Earth's orbit.
