Solar System, Magnetic Field, and Global Wamring

Which layer of Earth is responsible for the Earth's magnetic field?

• crust because it protects the Earth

• mantle because of the convection currents

• inner core because it is solid

• outer core because the liquid material is spinning around the inner core, creating a magnet

Which two elements are mainly found in the inner and outer core?

• iron and nitrogen

• iron and nickel

• nitrogen and basalt

• granite and basalt

Trees are so important to our environment because they absorb (sink) which greenhouse gas?

• methane

• water vapor

• carbon dioxide

• oxygen

Choose 3 of the leading contributors of carbon dioxide that are contributing to global warming.

• forest fires

• car exhaust

• human breathing

• factory pollution

A student made a model of how the planets orbit the Sun. She used a tennis ball to represent the Sun. She used ping-pong balls to represent each planet and painted each one a different color. Then she placed all the ping-pong balls equal distances apart in a line extending out from the Sun. What are two limitations to this model?

• She used the same size balls to represent the planets.

• She made the planets orbit the sun.

• The planets are not the not correct distances from the sun.

• The solar system can't be modeled using actual objects.

How do the sizes nets (within the asteroid belt) compare to the sizes of the outer planets (beyond the asteroid belt)?

• the inner planets are larger

• There is no size difference between the inner & outer planets

• the outer planets are smaller

• the inner planets are smaller

Describe how the distance between the orbits of the inner (within the asteroid belt) compare to the distances between the orbits of the outer planets (beyond the asteroid belt).

• The distances between orbits of the outer planets are much smaller.

• The distances between orbits of the inner planets are much larger.

• The distances between orbits of the outer planets are much larger.

• There is no difference between the distances of the orbits of the inner planets & the outer planets

The Earth's orbit is shaped more like am ellipse (oval) as it circles the Sun. Because of this shape, the Earth is actually closer to the Sun during parts of the year and farther during others.

• True

• False

What is wrong with the picture of the solar system.

• All of the planets should have been much FARTHER apart.

• The planets are NOT colorful. They are white

• The terrestrial planets should be closer together, while the gaseous planets should be further apart.
