What are the conditions necessary for a terrestrial planet to have a strong magnetic field? Both a molten metallic core and reasonably fast rotation.
Which of the following best describes convection?
1 Answer. It is the process in which warm material expands and rises while cool material contracts and falls.
What are the three main sources of internal heat for terrestrial planets quizlet?
What are the sources of internal heat for terrestrial planets? differentiation, collisions from other bodies, radioactive decay, gravitational compression.
What circumstances are necessary for differentiation to occur?
What is necessary for differentiation to occur in a planet? It must be a mix of materials of different density and the materials inside must be able to flow.
Why does convection occur in the troposphere but not in the stratosphere?
9. Why does convection occur in the troposphere, leading to active weather, but not in the stratosphere? Convection causes heating in troposphere because it drops in temperature with altitude, but has a relatively high density of air.
What conditions are thought to be necessary for a terrestrial planet?
What are the conditions necessary for a terrestrial planet to have a strong magnetic field? Very high pressures, like those found deep within planetary interiors, can compress rocks so much that they stay solid even when temperatures are high enough to melt them under ordinary conditions.
What three conditions must be met in order for a planet to generate a magnetic field?
The conditions necessary for this process to take place include the existence of a large volume of electrically conducting fluid (the liquid iron alloy at the core); the energy to drive this electrical dynamo through convection (the transfer of heat from the bottom to the top of core as the liquid cools); and the …
What are three situations where convection occurs?
Everyday Examples of Convection radiator – A radiator puts warm air out at the top and draws in cooler air at the bottom. steaming cup of hot tea – The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. ice melting – Ice melts because heat moves to the ice from the air.
In which of the following conditions will conduction most likely occur?
Conduction occurs more readily in solids and liquids, where the particles are closer together than in gases, where particles are further apart. The rate of energy transfer by conduction is higher when there is a large temperature difference between the substances that are in contact.
How does the resonance among Io Europa and Ganymede make their orbits slightly elliptical and how that causes thermal heating?
Therefore, all three planets line up for every orbit of Ganymede, and Io and Europa line up twice each Ganymede orbit. The gravitational tugs from their sister moons add up over time, and these tugs are always in the same direction. Therefore, the moons' orbits become slightly elliptical over time.
What is necessary for differentiation to occur in a planet choose all that apply?
What is necessary for differentiation to occur in a planet? It must be a mix of materials of different density and the materials inside must be able to flow.
How old is the Earth?
4.543 billion yearsEarth / Age
How does convection occur in troposphere?
The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe.
Why does Venus have such a great difference in temperature between its no greenhouse temperature and its actual temperature?
Why does Venus have such a great difference in temperature between its "no atmosphere" temperature and its actual temperature? It has a large amount of greenhouse gases in its atmosphere. Which planet experiences the greatest change between its actual day temperature and actual night temperature?
What are the three 3 necessary conditions for a planet to have a global magnetic field?
The conditions necessary for this process to take place include the existence of a large volume of electrically conducting fluid (the liquid iron alloy at the core); the energy to drive this electrical dynamo through convection (the transfer of heat from the bottom to the top of core as the liquid cools); and the …
Which set of conditions is necessary for a planet to have plate tectonics?
2 Answers. Show activity on this post. Plate tectonics appears to require multiple factors all arraigned in feedback loops. The planet must be large enough that it's surface to volume ratios is low enough to trap enough heat from radioactive decay to power tectonic motion.
What are the conditions that will produce a global magnetic field around a planet?
If you have a rotating electric current, it will create a magnetic field. On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet.
Which of the following planets have conditions that can support life explain your answer?
Earth may be the only planet in the solar system which supports life.

What is convection How does it occur?
How does convection work? Convection works by areas of a liquid or gas heating or cooling greater than their surroundings, causing differences in temperature. These temperature differences then cause the areas to move as the hotter, less dense areas rise, and the cooler, more dense areas sink.
How do convection occur?
How does convection work? Convection works by areas of a liquid or gas heating or cooling greater than their surroundings, causing differences in temperature. These temperature differences then cause the areas to move as the hotter, less dense areas rise, and the cooler, more dense areas sink.
What most likely to happen when convection occurs?
The warmer air expands, becoming less dense than the surrounding air mass, and creating a thermal low. The mass of lighter air rises, and as it does, it cools by expansion at lower air pressures. It stops rising when it has cooled to the same temperature as the surrounding air.
How the resonance among Io Europa and Ganymede makes their orbits slightly elliptical?
Therefore, all three planets line up for every orbit of Ganymede, and Io and Europa line up twice each Ganymede orbit. The gravitational tugs from their sister moons add up over time, and these tugs are always in the same direction. Therefore, the moons' orbits become slightly elliptical over time.
What effect has orbital resonance had on the eccentricities of the orbits of Io Europa and Ganymede?
(Right) Io and Europa experience a mutual conjunction one Io day later, while Europa has moved along half an orbit, and Ganymede has progressed through one-quarter of its orbit. The resonance forces Europa's eccentricity to be nonzero, causing tidal heating and geological consequences.
Which one explains why convection can occur in the troposphere but not in the stratosphere?
Which one explains why convection can occur in the troposphere but not in the stratosphere? Temperature declines with altitude in the troposphere but increases with altitude in the stratosphere.
Who created Earth?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
Who discovered Earth?
The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations.
How does convection occur in the atmosphere?
Convection happens because warm air is less dense than the cold air around it, so it is lighter and rises or goes up in the atmosphere. Evidence of convection happening is seen with the formation and growth of cumulus clouds.
How does convection occur in the atmosphere quizlet?
How does convection occur in the troposphere? Warm air rises and cool air sinks. Which is a type of heat transfer that causes the air at the top floor of a building to be hotter than the air at the bottom floor of a building?
