Textbook Question
Chapter 3, Problem 14EAP
Each of the following statements makes some type of claim. Decide in each case whether the claim could be evaluated scientifically or whether it falls into the realm of nonscience. Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.
14. There are no lakes or seas on the surface of Mars today.

Activity #1. Compare and Contrast. Similarities and differences of Venus, Earth and Mars.
Do this on a separate sheet of paper.
1. Compare and contrast the three (3) terrestrial planets using table 1.
2. Provide explanations for your observations using table 2.
3. Answer the following guide questions.
Guide questions:
1. Does planet size affect gravity?
2. Why do you think Venus has the highest mean temperature among the three planets?
3. Is presence of water a primary factor for a planet to sustain life? Why or why not?
4. Based on your observations using table 2, what are the notable features that makes the
earth the only habitable planet among the three terrestrial planets?
5. What conclusions can you make?
The principle cause of our intense interest in Mars in the decades before the dawn of the space age was that
Answers:
A.
a few astronomers believed that they saw evidence of an intelligent civilization on Mars.
B.
Mars has seasons just like the Earth and therefore should be inhabitable by humans.
C.
Mars has an unusual surface color and global dust storms, creating strange weather patterns.
D.
Mars has unusual orbital properties making our understanding of its motion around the Sun very difficult.
Let's use Kepler's laws for the inner planets. Use the following distances from the sun to calculate the orbital period for each of these planets. Express your answer in terms of Earth years to two significant figures.
Note: Use Kepler's law directly. Don't just Google the answers, as they will be a little bit different.
When you have calculated them, only submit the value for Mercury.

In August of 2006, leading astronomers established new guidelines and declared that Pluto is no longer a planet. Which of the following is either false or least consistent with the new guidelines? Group of answer choices Pluto is by far the largest known object in the Kuiper belt, while Eris is the largest known object in the asteroid belt. A planet must have cleared the neighborhood around its orbit. Pluto is automatically disqualified from being a planet because its oblong orbit overlaps with Neptune's. A planet must have sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a nearly round shape. Pluto and the asteroid Ceres are both now classified as dwarf planets.arrow_forwardWe need to create a scale model of the solar system (by shrinking the sun down to the size of a basketball or ~30cm). First, we will need to scale down actual solar system dimensions (planet diameters and average orbital radiuses) by converting our units. There are two blank spaces in the table below. We will effectively fill in the missing data in the next set of questions. Use the example below to help you. Example: What is the scaled diameter of Mercury if the Sun is scaled to the size of a basketball (30 cm)? The actual diameter of Mercury is 4879 km The Sun's diameter is 1392000 km If the Sun is to be reduced to the size of a basketball, then the conversion we need for this equation will be: 30cm1392000km Here is how we run the conversion: 4879km×30cm1392000km=0.105cm or 0.11cm if we were to round our answer. This means that if the sun in our model is the size of a basketball, Mercury is the size of a grain of sand. We can also see by looking at the table, that we would…arrow_forward

- Pretend you are a NASA executive or a legislator. Design a new mission in our solar system. Pick any object in the system and decide whether you want to send an orbiter, a lander, a rover, some combination or those, a manned mission, or something else. What interests you about this object? What science questions can we answer? In basic terms, what kind of scientific instruments might you want to include on your mission? Justify your decisions with what you know about the scientific method, astronomy techniques, and the object itself from this class.arrow_forwardIf we send astronauts to Mars, there will be a time delay anytime we send or receive messages to them here on Earth. Given that Mars is an average of 54.6 million km away from Earth, how long is this time delay for a 2-way 'round-trip' communication - sent to Earth, then back to Mars?
