Station 4: Regents Practice

1. Base your answer to the following question on your knowledge of Earth science. The diagram represents the elliptical orbit for one planet in our solar system. The two foci of the orbit are shown as the Sun and F2. 

which condition would produce an orbit with a greater eccentricity?  

• A) a decrease in the distance between the Sun and F2 

• B) an increase in the distance between the Sun and F2 

• C) a constant decrease in the orbital velocity of the planet

• D) a constant increase in the orbital velocity of the planet

1. Base your answer to the following question on the  diagram below which shows the Earth's orbit and the partial orbit of a comet on the same plane around the Sun. 

Compared with the Earth's orbit, the comet's orbit has

A) less eccentricity

B) more eccentricity

C) the same eccentricity 

• less eccentricity

• more eccentricity

• the same eccentricity 

1.  The gravitational attraction between two objects in the solar system is greatest when their masses are

• small, and the objects are close together

• small, and the objects are far apart

• large, and the objects are far apart

• large, and the objects are close together

Base your answers to questions 6 and 7 on the diagram below, which shows the orbit of planet D around the star Upsilon Andromedae. The dashed lines show where the paths of the first four planets

of our solar system would be located if they were going around Upsilon Andromedae instead of the Sun. All distances are drawn to scale.

Planet D has a much ​ (a)   eccentric orbit than any of the first four planets of our solar system.

The diagram below represents the elliptical orbit of the Earth around the Sun.

Which equation should be used to find the eccentricity of the Earth's orbit?

• eccentricity =299,000,000km/5,000,000 km

• eccentricity = 5,000,000km/299,000,000 km

• eccentricity = 299,000,000 km - 5,000,000 km

• eccentricity =

  5,000,000 km/299,000,000 km - 5,000,000 km

(b) Aphelion

• Higher gravity

• Lower gravity

• Faster velocity

• slower velocity
