U1 Earth in Space Test Sp25

The diagram shows Earth's magnetosphere interacting with solar wind and radiation. What effect does Earth's magnetic field have on solar wind?

• Repels solar wind

• Attracts solar wind

• Neutralizes solar wind

• Absorbs solar wind

What is the effect of Earth's magnetosphere on the erosion caused by harmful particles from the Sun?

• Reduces erosion

• Increases erosion

• Has no effect on erosion

• Doubles the erosion

Which conclusion is BEST supported by the data?

• Temperatures of land are more likely to fluctuate because sand has a lower heat capacity.

• Temperatures of land are more likely to fluctuate because sand has a higher heat capacity.

• Temperatures of water are more likely to fluctuate because water has a lower heat capacity.

• Temperatures of water are more likely to fluctuate because water has a higher heat capacity.

Based on Kepler's First Law, what shape do planets follow in their orbit around the Sun?

• Circular

• Elliptical

• Parabolic

• Hyperbolic

According to Kepler's Second Law, when does a planet move faster in its orbit?

• When it is farther from the Sun

• When it is closer to the Sun

• When it is at the midpoint of its orbit

• When it is moving away from the Sun

What does Kepler's Third Law relate to in terms of planetary motion?

• The speed of a planet

• The shape of a planet's orbit

• The period and average distance of a planet

• The mass of a planet

Based on Kepler's laws, which statement is MOST LIKELY correct about comets?

• Comets do not have the Sun as a focus.

• Comets spend most of their time close to the Sun.

• Comets spend most of their time far from the Sun.

• Comets travel with a uniform speed.

According to the nebular theory, how did the Sun and planets in the solar system begin?

• As a giant cloud of molecular gas and dust

• As a collection of asteroids

• As a group of comets

• As a single large star

What event triggered the gravitational collapse of the solar nebula according to the nebular theory?

• A nearby shock wave from a supernova

• A collision with a large asteroid

• The explosion of a nearby planet

• The formation of a black hole

Which statement about planetary impact craters in the early formation of the solar system is BEST supported by the nebular theory?

• All planets likely experienced few collisions that resulted in impact craters.

• All planets likely experienced many collisions that resulted in impact craters.

• The Jovian planets formed before others, which led to more collisions and impact craters.

• The terrestrial planets formed before others, which led to fewer collisions and impact craters.
