Astronomy Big Bang- Rev & Rotation

The diagram represents the apparent daily path of the sun across the sky in the Northern Hemisphere on the dates indicated. Which observation about the Sun’s apparent path at this location on June 21 is best supported by the diagram?

• The Sun appears to move across the sky at a rate of 1º per hour.

• The Sun’s total daytime path is shortest in this date.

• Sunrise occurs north of east

• Sunset occurs south of west.

Which table correctly classifies this star at points 3 and 4?

• 
• 
• 
• 

The diagram represents a time-exposure photograph of Polaris and star trails, with an angular protractor to measure apparent motion.

• 3 hours

• 4 hours

• 5 hours

• 6 hours

The diagram represents a simplified model of the early formation of Earth’s interior. Early in its formation, Earth was a molten mass of evenly mixed composition. During the next few million years, the heavier and more dense elements sank to the center, while lighter and less dense elements rose toward the surface. This is called chemical fractionation. Approximately how many years ago did Earth and other planets in our solar system begin the process of chemical fractionation?

• 4600 million years ago

• 500 million years ago

• 13.8 billion years ago

• 6.6 billion years ago

Between which two planets are most asteroids located?

• Saturn and Uranus

• Mars and Jupiter

• Earth and Mars

• Jupiter and Saturn

Base your answer to the question on the diagram below, which represents the Sun’s apparent paths and the solar noon positions for an observer at 42° N latitude on December 21, September 23, and June 21. How many hours occurred between sunrise and solar noon on September 23?

• 24

• 12

• 6

• 8

Which factor has the greatest influence on the number of daylight hours that a particular Earth surface location receives?

• Distance from the sum

• orbital velocity

• latitude

• longitutde

Which characteristic of the planets in our solar system increases as the distance from the Sun increases?

• period of rotation

• eccentricity of orbit

• equatorial diameter

• period of revolution

A major piece of evidence supporting the Big Bang theory is the observation that wavelengths of light from stars in distant galaxies show a

• redshift, appearing to be longer

• blueshift, appearing to be longer

• blueshift, appearing to be shorter

Which object in space emits light because it releases energy produced by nuclear fusion?

• Halley’s comet

• Venus

• Earth’s Moon

• Polaris
