What largely determines the level of volcanic and tectonic activity on the Galilean moons quizlet?
What did the Cassini spacecraft and its Huygens probe discover on the surface of Titan, the largest of Saturn’s moons? … What largely determines the level of volcanic and tectonic activity on the Galilean moons? proximity to Jupiter and its extreme tidal forces. Which of the following is true about Pluto?
What is unusual about Uranus quizlet?
What is unusual about Uranus’s axis of rotation? It is tilted almost 90 degrees and lies on its side.
What are pieces of evidence that the Sun is the center of the solar system not the Earth?
He discovered that the sun has sunspots, which appear to be dark in color. Galileo’s discoveries about the Moon, Jupiter’s moons, Venus, and sunspots supported the idea that the Sun – not the Earth – was the center of the Universe, as was commonly believed at the time.
Who discovered Earth?
Eratosthenes then measured the angle of a shadow cast by a stick at noon on the summer solstice in Alexandria, and found it made an angle of about 7.2 degrees, or about 1/50 of a complete circle.
Which statement best explains an aspect of the differential heating of Earth’s surface by the Sun?
Which statement best explains an aspect of the differential heating of Earth’s surface by the Sun? Liquids and solids absorb and store heat differently.
What are the dominant features on the surface of Mercury quizlet?
Craters – Like the Moon, the dominant surface feature on Mercury is craters. Furthermore, all craters on Mercury show the same morphological characteristics as their lunar counterparts.
What does this photograph indicate about the ages between the light colored area on the right versus the dark colored area on the left?
What does this photograph indicate about the ages between the light-colored area on the right versus the dark-colored area on the left? The area on the right is older because it contains more craters than the area on the left.
Is Mercury’s surface heavily cratered?
Mercury and the Moon
Impact craters dominate the surfaces of Mercury and the Earth’s Moon. Both bodies lack liquid water on their surfaces that would erode impact craters over time. They also lack an atmosphere which, on planets like the Earth and Venus, could disintegrate meteoroids before they impact the surface.
What term is used to study of Mars?
The geology of Mars is the scientific study of the surface, crust, and interior of the planet Mars. … A neologism, areology, from the Greek word Arēs (Mars), sometimes appears as a synonym for Mars’s geology in the popular media and works of science fiction (e.g. Kim Stanley Robinson’s Mars trilogy).
How do scientists get maps of Venus surface?
SAR imaging
Microwave radiation is used to penetrate the thick atmosphere and map the surface of Venus. The SAR images are black and white images, which show the surface features using the intensity of radar return (echo), either due to surface roughness or orientation.
What geologic process was formed on Mars?
The most likely geologic process to form the channel on Mars is continental drift, the same process that forms modern channels like the mid-Atlantic…
What are the 3 theories of the solar system?
These are the Nebular Hypothesis of Laplace, the Planetesimal Hypothesis of Chamberlin and Moulton, and the Capture Theory of See.

What are the theories involved in the formation of universe and solar system?
The most widely accepted hypothesis of planetary formation is known as the nebular hypothesis. This hypothesis posits that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years.
What surface region of the Moon is the oldest How do we know this quizlet?
How do astronomers know whether lunar highlands or lunar maria have older surfaces? The presence of many more craters means that there has been more time for impacts in the highlands, so they are older surfaces. The moon’s craters Copernicus and Tycho both have circular rims with a central peak.
What is the youngest feature on the Moon?
2 Maria and Basins. The lunar maria (or plains), which were formed between 3.1 and 3.9 billion years ago, are the youngest geologic units on the lunar surface, except for more recent impact craters.
Which of the following is the oldest feature on the Moon surface?
lunar highlands
The oldest lunar features are the lunar highlands.How do most uranium deposits form quizlet?
How do most uranium deposits form? sediments. Oil degraded by bacteria which consume the lighter components of the oil leaving a thick sludge.
What is the current theory for the formation of our solar system quizlet?
The nebular theory states that our solar system formed from the gravitational collapse of a giant interstellar gas cloud—the solar nebula. (Nebula is the Latin word for cloud.) In 1755, Immanuel Kant proposed the solar system formed from the gravitational collapse of an interstellar cloud of gas.
What did the Cassini spacecraft and its Huygens probe discover on the surface of Titan the largest of Saturn’s moons quizlet?
What did the Cassini spacecraft and its Huygens probe discover on the surface of Titan, the largest of Saturn’s moons? Networks of drainages apparently carved by liquids.
Do Jupiter and Saturn have solid surfaces?
A: Gas giants like Jupiter and Saturn do not have solid surfaces in the sense that if you dropped in a penny, it would never land with a “clink.” These bodies are mostly composed of hydrogen at temperatures above the “critical point” for hydrogen, meaning there is no sharp boundary between solid, liquid, and gas …Why does such a limit exist?
Why does such a limit exist? The Roche limit is the closest distance from the center of a planet that a satellite can approach without being pulled apart by tidal forces. This limit exists because tidal forces, when too close, are what cause it to be ripped apart.
