What are the two geological features that appear to set Earth apart from all the other terrestrial worlds? plate tectonics and widespread erosion

Why doesn’t Venus have a magnetic field like the Earth quizlet?

Venus is too close to the sun. Venus has no molten iron core. … (the distance of the planet from the sun does not affect its ability to have a magnetic field.)

Does Venus lack a magnetic field?

Since Venus has no intrinsic magnetic field to act as a shield against incoming charged particles, the solar wind sometimes interacts directly with the upper atmosphere. However, Venus is partially protected by an induced magnetic field.

Why do some planets not have magnetic fields?

No, not all planets have magnetic fields. … Mercury’s field is weak because it rotates so slowly. Venus doesn’t have an appreciable field because there appears to be little convection in its molten interior. Mars doesn’t have an appreciable field – although it did in the past – because its interior has solidified.

Why doesn’t Venus have a moon?

Most likely because they are too close to the Sun. Any moon with too great a distance from these planets would be in an unstable orbit and be captured by the Sun. If they were too close to these planets they would be destroyed by tidal gravitational forces.

Which of the following best explains why Venus is so warm?

Venus is so hot because it is surrounded by a very thick atmosphere which is about 100 times more massive than our atmosphere here on Earth. As sunlight passes through the atmosphere, it heats up the surface of Venus. … The heat becomes trapped and builds up to extremely high temperatures.

Which of the following describes the planet Venus?

Venus is the second planet from the Sun, and is Earth’s closest neighbor in the solar system. Venus is the brightest object in the sky after the Sun and the Moon, and sometimes looks like a bright star in the morning or evening sky. The planet is a little smaller than Earth, and is similar to Earth inside.

Which of the following is the main reason why Venus has so little wind erosion?

Which of the following is the underlying reason why Venus has so little wind erosion? –Without rotation, it lacks significant wind and therefore lacks wind erosion.

Why does Venus appear so bright to the eye quizlet?

Why does Venus appear so bright to the eye? The planet’s cloud-cover is highly reflective, reflecting 60% of the Sun’s light. -Venus is closer to the Sun, so gets more intense sunlight. -It gets closer to us than any other planet does.

What is peculiar about Venus’s rotation and why does Venus rotate that way?

What is peculiar about Venus’s rotation and why does Venus rotate that way? It is very slow and retrograde. The reason is unknown, but may simply be a matter of chance. Why did early studies of Venus lead astronomers to such an inaccurate picture of the planet’s surface conditions?

How do the continents of Venus differ from Earth’s continents?

How do the continents of Venus differ from Earth’s continents? — There are only two continents that occupy roughly 8% of its surface (as opposed to Earth’s continents which occupy 25% of its space). There also seems to be no evidence of plate tectonics on Venus.

Does Venus have a strong magnetic field?

Unlike Earth, Venus lacks a magnetic field. Its ionosphere separates the atmosphere from outer space and the solar wind. This ionized layer excludes the solar magnetic field, giving Venus a distinct magnetic environment.

Has Venus got a magnetic field?

Unlike Earth, which has an intrinsic magnetic field from the sloshing, molten material inside its core, Venus generates its magnetic field from the interaction of the Sun’s solar wind with the planet’s ionosphere, the atmospheric region filled with charged atoms. Those charged atoms create electric currents.

Which planet has no magnetic field?

Probes found that Mars and Venus do not have a significant magnetic field. Jupiter, Saturn, Uranus, and Neptune all have magnetic fields much stronger than that of the Earth. Jupiter is the champion- having the largest magnetic field. The mechanism that causes their magnetic fields is not fully understood.

What if Venus had a magnetic field?

The total length of the 10,000 rings wrapped around Venus would be 400 billion metres. So the whole structure would generate an incredible 2,000 trillion Watts of heat. In the course of a year maintaining the magnetic field in this way would consume 18 million trillion watt hours of Energy.

Why do some planets have strong magnetic fields?

Planetary magnetic fields are believed to be caused by strong convective currents in planetary cores. These currents require for their production complete melting over of a large region of the planet’s interior and rapid rotation of the planet.

Why do Venus and Mars lack magnetic fields?

The absence of an intrinsic magnetic field in Venus is due to the lack of dynamo which is responsible for a strong global magnetic field due to the motion of an electrically conducting and convecting fluid inside the planet. … However, Mars does possess a weak magnetic moment due to the crustal magnetic anomalies.

Why doesn’t Venus have any rings?

Unfortunately, Venus doesn’t have rings. … It’s too warm around Venus, so that any water would be a gas or liquid. It would either collect into oceans, like Earth, or be pushed out into deeper space by the Sun’s solar wind. Another way that planets can have rings is when micrometeoroids smash into a small moon.

Why do some planets not have moons?

So, why don’t moons have their own moons? The answer is that the planet they are orbiting has a much stronger gravitational pull, so over time it would selfishly take other objects in as another moon for itself.

Does Venus need a moon?

But what about Venus, the planet that for a while, astronomers thought about as Earth’s twin? The answer is no moons at all. That’s right, Venus (and the planet Mercury) are the only two planets that don’t have a single natural moon orbiting them.

Why is Venus the warmest planet?

The carbon dioxide traps most of the heat from the Sun. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury.

Which of the following best explains why Venus has a higher temperature than Mercury?

Venus has a higher average temperature than Mercury. The fact that Venus is hotter than Mercury despite being nearly twice as far from the Sun tells us that its thick carbon dioxide atmosphere must warm it significantly—just as we expect from the theory of the greenhouse effect.

Which of the following explains why might Venus has a weaker Coriolis effect than Earth?

Why is the Coriolis effect so weak on Venus? Because Venus rotates so slowly. All of the following have occurred over long periods of time on Earth. … Most of the gases that have been released from volcanoes on Earth later returned to the surface.

Can Venus support life Why or why not?

To date, no definitive proof has been found of past or present life on Venus. … With extreme surface temperatures reaching nearly 735 K (462 °C; 863 °F) and an atmospheric pressure 90 times that of Earth, the conditions on Venus make water-based life as we know it unlikely on the surface of the planet.

Why does Venus rotate in opposite direction?

For starters, it spins in the opposite direction from most other planets, including Earth, so that on Venus the sun rises in the west. … Such tides, combined with friction between Venus’s mantle and core, could have caused the flip in the first place.

What are 3 characteristics of Venus?

Structure and Surface
  • Venus is the hottest planet in our solar system.
  • Venus is a terrestrial planet. It is small and rocky.
  • Venus has a thick atmosphere. It traps heat and makes Venus very hot.
  • Venus has an active surface, including volcanoes!
  • Venus spins the opposite direction of Earth and most other planets.

Which of the following is thought to explain why Venus has so much more atmospheric gas than Earth?

Venus has gained much more gas through outgassing than has Earth. Earth has lost much more gas to thermal escape than has Venus. Because of its lack of magnetic field, Venus has been able to gain gas through the impacts of solar wind particles, while Earth has not gained gas in this way.

Which of the following most likely explains why Venus does not have a strong magnetic field quizlet?

Which of the following most likely explains why Venus does not have a strong magnetic field? Its rotation is too slow. What are the conditions necessary for a terrestrial planet to have a strong magnetic field? … Which two properties are most important in determining the surface temperature of a planet?

Why do you expect to find only large impact craters on the surface of Venus?

Compared to Mercury, the Moon and other such bodies, Venus has very few craters. In part, this is because Venus’s dense atmosphere burns up smaller meteorites before they hit the surface. … The impact crater distribution appears to be most consistent with models that call for a near-complete resurfacing of the planet.

Why Venus does appear so bright to the naked eye?

Venus is so bright because its thick clouds reflect most of the sunlight that reaches it (about 70%) back into space, and because it is the closest planet to Earth. Venus can often be seen within a few hours after sunset or before sunrise as the brightest object in the sky (other than the moon).

What is not a reason for Venus to now be so dry?

What is NOT a reason for Venus to now be so dry? Venus never had any water because it is too close to the Sun.

What is thought to have caused the craters on Venus quizlet?

What is thought to have caused the craters on Venus? Most are volcanic in origin; some are due to meteoritic impacts. Comparing the clouds of Earth and Venus, we find that: ours lie in the troposphere, within 10 kilometer of our surface, but Venus has a higher troposphere, with its clouds about 40 kilometers high.
