Assignment #2

I do not own any of these pictures or content all information is obtained from Mastering Astronomy, Pearson.


Sorting Task: Characteristics of Reflecting and Refracting Telescopes

Listed following are distinguishing characteristics and examples of reflecting and refracting telescopes. Match these to the appropriate category
Obtained from Mastering Astronomy


Vocabulary in Context: Characteristics of Telescopes

  1. The angular resolution of the Hubble Space Telescope is better for shorter (bluer) wavelengths of light than for longer (redder) wavelengths of light.
  2. The large research observatories on Mauna Kea use giant reflecting telescopes.
  3. Spectrographs separate the various colors of light, allowing astronomers to determine stellar composition and many other stellar properties
  4. The twin 10-m Keck telescopes can work together to obtain better angular resolution through a technique known as interferometry.
  5. The Chandra x-ray observatory focuses X rays with grazing incidence mirrors.
  6. A 10-meter telescope has a larger light-collecting area than a 4-meter telescope.
  7. Galileo’s telescope designs using lenses were examples of refracting telescopes.

Obtained from Mastering Astronomy


Ranking Task: Planet Temperature, Orbital Period, and Number of Moons

Part A
The following images show five planets in our solar system. Rank these planets from left to right based on their average surface (or cloud-top) temperature, from highest to lowest. (Not to scale.)
Obtained from Mastering Astronomy

 Part B
The following images show five planets in our solar system. Rank these planets from left to right based on the amount of time it takes them to orbit the Sun, from longest to shortest. (Not to scale.)
Obtained from Mastering Astronomy

Part C
The following images show four planets in our solar system. Rank these planets from left to right based on the number of moons that orbit them, from highest to lowest. (Not to scale.)

Sorting Task: Characteristics of Terrestrial and Jovian Planets

Part A
Listed following are characteristics that can identify a planet as either terrestrial or jovian. Match these to the appropriate category.
Obtained from Mastering Astronomy


Vocabulary in Context: Names of the Planets
  1. Neptune is about 30 times as far from the Sun as our own planet.
  2. Venus is the planet with the highest average surface temperature.
  3. The planet with the lowest average density is Saturn.
  4. The planet that orbits closest to the Sun is Mercury.
  5. The only rock planet to have more than one moon is Mars.
  6. Jupiter is the jovian planet that orbits closest to the Sun.
  7. Uranus has a rotational axis that is tilted so much it lies nearly in the plane of its obit.
  8. Most of the surface of Earth is covered with liquid water.

Ranking Task: Matter in the Solar System
Part A
The materials that made up the solar nebula can be categorized into the four general types as follows. Rank these materials from left to right based on their abundance in the solar nebula, from highest to lowest.
Obtained from Mastering Astronomy

Part B
The materials that made up the solar nebula can be categorized into these four general types. Rank these materials from left to right based on the temperature at which each would condense into a solid, from highest to lowest. Note: For a substance that does not condense at all, rank it as very low temperature.
Obtained from Mastering Astronomy

Part C
As you’ve learned from Part B, hydrogen and helium gas never condense under conditions found in the solar nebula. The remaining three categories of material in the solar nebula are shown again here. Rank these materials from left to right based on the distance from the Sun at which they could condense into a solid in the solar nebula, from farthest to closest.
Obtained from Mastering Astronomy


Sorting Task: Formation of Terrestrial and Jovian Planets

Part A
Listed following are statements that, based on our current theory of solar system formation, apply either to the formation of terrestrial planets or of jovian planets, but not both. Match these to the appropriate category.
Obtained from Mastering Astronomy



Ranking Task: Formation of the Solar System

Part A
Provided following are stages that occurred during the formation of our solar system. Rank these stages from left to right based on when they occurred, from first to last.
Obtained from Mastering Astronomy

  
Vocabulary in Context: Solar System Formation

  1. The first few hundred million years of the solar system 19s history were the time of the heavy bombardment, during which Earth suffered many large impacts
  2. The era of planet formation ended when the remaining hydrogen and helium gas of the solar nebula was swept into interstellar space by the solar wind.
  3. Ice can form from a gas through the process of condensation.
  4. Hydrogen compounds in the solar system can condense into ices only beyond the frost line.
  5. Our Moon was most likely formed by a collision between Earth and a Mars-sized planetesimal.
  6. Mars was formed by the accretion of smaller objects.
  7. Our solar system was created by the gravitational collapse of the solar nebula.
  8. Radiometric dating allows us to determine the age of a solid rock.

Ranking Task: Tectonic Activity of the Terrestrial Planets
Part A
Shown below are the four terrestrial planets of our solar system. Assume that all the planets started out equally hot inside. Rank the planets based on their expected cooling rates, from fastest cooling to slowest cooling. 
Obtained from Mastering Astronomy


Part B
Shown following are three terrestrial planets of our solar system. Rank the planets based on the amount of time the surface of the planet has had a moderate to high level of volcanic/tectonic activity, from longest to shortest.
Obtained from Mastering Astronomy


Ranking Task: Atmospheric Pressure

Part A
The following images show the four terrestrial planets in our solar system. Rank these planets from left to right based on the atmospheric pressure at the surface, from highest to lowest. (Not to scale.)
Obtained from Mastering Astronomy

Part B
The following images show the four terrestrial planets in our solar system. Rank these planets from left to right based on the total amount of gas in their atmospheres, from most to least. (Not to scale.)
Obtained from Mastering Astronomy



Visual Acticity: Exploring the Cause of the Greenhouse Effect

Part A
On a cloudless day, what happens to most of the visible light headed toward Earth?

It reached Earth’s surface, where some is reflected and some is absorbed.

Part B
On a day with complete cloud cover, what happens to the visible light headed toward Earth?

The clouds reflect much of it back to space, though some still reaches the surface.

Part C
What happens to the energy that the ground absorbs in the form of visible sunlight?

It is returned upward in the form of infrared light.

Part D
The greenhouse effect raises Earth’s surface temperature (from what it would be otherwise) because the infrared light radiated by Earth’s surface __________.

Is temporarily absorbed by greenhouse gases and then reemitted in random directions

Sorting Task: Terrestrial Planetary Atmospheres

Part A
Listed following are characteristics of the atmospheres of Venus, Earth, and Mars. Match each atmospheric characteristic to the appropriate planet.
