The picture below shows a globe of the world with Barrow, Alaska circled. For almost three months, mid-May to mid-August, the Sun never sets in Barrow, Alaska. Which is the most likely reason for the Sun always shining in the Summer in Barrow?

• Earth only rotates on its axis during the winter, so the same part of Earth faces the Sun all summer

• Only the middle of the Earth rotates around its axis, so the top of Earth always faces the Sun

• Earth's axis is tilted, so some of the time parts of Earth face the Sun for the entire daily rotation

• The Sun's axis is tilted, so some of the time parts of Earth face the Sun for the entire daily rotation

This image explains this path is the result of -

• the magnetic attraction between Earth and the Sun

• potential energy stored in Earth that originated in the Sun

• The gravitational attraction between the sun and Earth

• Electromagnetic energy from the Sun pulling on Earth

Which of these locations on Earth experiences the least change in the number of daylight hours throughout the year?

• North Pole

• Tropic of Cancer

• Equator

• Tropic of Capricorn

Which of these changes would likely occur if the rate of Earth's rotation on its axis increased?

• The length of the seasons would be shorter

• The length of the seasons would be longer

• The length of the day would be shorter

• The length of a day would be longer

In July 1994 the comet Shoemaker-Levy 9 collided with the planet Jupiter, as scientists had predicted. To be able to accurately predict when a comet will collide with a planet, it is essential to understand -

• the composition of a planet's atmosphere

• the gravitational attraction that exists between all bodies

• the attraction of opposite poles of a magnet to each other

• the formation of comets

John sees a bright object in the sky that appears to be following no fixed path. Certain times of the year it even seems to be going in an opposite direction from other times. What kind of object is John most likely seeing?

• A planet, because its orbit makes it appear to move randomly

• A star, because their movement through the sky appears random

• A planet, because planets move in the opposite direction from Earth

• A star, because some stars have orbital paths they follow
