Chapter 11: Problem 20

Do Venus and Mars have continents like those on Earth?

Short Answer

Expert verified
No, Venus and Mars do not have continents like those on Earth. They lack the plate tectonics that cause the formation of continents on Earth.

Step by step solution

01

Understanding Planetary Geology

Research and analyze the surface geology and structure of Venus and Mars. Note down their characteristics, including the presence or absence of continents, tectonic plates, and other significant geological features. Document the similarities and differences with Earth's structure.
02

Compare with Earth

Contrast the researched information on the geological structures of Venus and Mars with Earth's continents, elaborating on why or why not these planets possess continents like Earth. Specifically focus on Earth's tectonic plates, which cause the formation of continents, and compare with these planets.
03

Formulate the Answer

Based on the comparative analysis of Venus, Mars, and Earth, formulate a concise answer regarding the presence or absence of Earth-like continents on Mars and Venus

Most popular questions from this chapter

Although the Viking Lander 1 and Viking Lander 2 landing sites are \(6500 \mathrm{~km}\) apart and have different geologic histories, the chemical compositions of the dust at both sites are nearly identical. (a) What does this suggest about the ability of the Martian winds to transport dust particles? (b) Would you expect that larger particles such as pebbles would also have identical chemical compositions at the two Viking Lander sites? Why or why not?

Describe the apparent motion of the Sun during a "day" on Venus relative to (a) the horizon and (b) the background stars. (Assume that you can see through the cloud cover.)

On Mars, the difference in elevation between the highest point (the summit of Olympus Mons) and the lowest point (the bottom of the Hellas Planitia basin) is \(30 \mathrm{~km}\). On Earth, the corresponding elevation difference (from the peak of Mount Everest to the bottom of the deepest ocean) is only \(20 \mathrm{~km}\). Discuss why the maximum elevation difference is so much greater on Mars.

Why is it impossible for liquid water to exist on Mars today? If liquid water existed on Mars in the past, what must have been different then?

Before about 350 ?.C., the ancient Greeks did not realize that Mercury seen in the morning sky (which they called Apollo) and seen in the evening sky (which they called Hermes) were actually the same planet. Discuss why you think it took some time to realize this.
