Which two factors are most important to the existence of plate tectonics on Earth quizlet?

Which two factors are most important to the existence of plate tectonics on Earth? Mantle convection helps move the plates, and the plates probably exist because the lithosphere was thin enough to break into these plates.

What are the basic requirements for a terrestrial world to have a global magnetic field? A core layer of molten, convecting material and sufficiently rapid rotation.

What do we mean when we say that the terrestrial worlds underwent differentiation quizlet?

What do we mean when we say that the terrestrial worlds underwent differentiation? When their interiors were molten, denser materials sank toward their centers and lighter materials rose toward their surfaces.

Which two geological processes have been most important in shaping the surface of the moon as we see it today?

The primary geologic processes that shaped the moon are the formation of craters, volcanic activity, and tectonic activity. Each of these will be dealt with in their respective sections below. Craters cover the surface of the moon. They are the result of high velocity impacts on the surface by meteorites.

What are two geological features that appear to set Earth apart from all the other terrestrial worlds?

What are the two geological features that appear to set Earth apart from all the other terrestrial worlds? Plate tectonics and widespread erosion. neither of these features appears to exist on any terrestrial world in our solar system.

What is the main source of heat inside the terrestrial planets?

Currently the terrestrial planets' primary source of heat is radioactivity.

What are the two geological features that appear to set Earth apart from other terrestrial worlds in our solar system?

Which two geological process appears to be most important in shaping the present surface of Venus?

8) Erosion is the most important geological process on Venus. 9) There is no erosion of surface features on the Moon. 10) In the inner solar system, the largest surface features are found on the largest planets. 11) Earth is the only terrestrial planet to have experienced tectonic stresses and volcanic activity.

What are the conditions necessary for a terrestrial planet?

What are the conditions necessary for a terrestrial planet to have a strong magnetic field? Both a molten metallic core and reasonably fast rotation.

What are the three main sources of internal heat for terrestrial planets?

The major processes that heat the interiors of the terrestrial worlds are…

Heat deposited as the planets were built from planetesimals.
Heat deposited as the planets underwent differentiation.
Heat released by radioactive decay.

What is the most important factor in determining if a terrestrial planet has liquid surface water?

What is the most important factor in determining if a terrestrial planet has liquid surface water? A planet's distance from the Sun. Why is the Earth's core composed of mostly metals (like iron and nickel)?

What physical processes are most important in shaping the surfaces of Venus and Earth?

Weathering and eolian transportation are, however, important geologic processes. Radar imagery of Venus shows broad smooth lowlands, volcanic rises (or domes) called uplands, and continent-sized areas of strongly deformed highlands.

What are the two main factors that control how a terrestrial planet’s surface will evolve?

The primary factors that appear to make Earth habitable are its relatively large size and its distance from the Sun. Distance from the Sun, along with the greenhouse effect, determines surface temperature.

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 are two main sources of internal heat in terrestrial planets?

Currently the terrestrial planets' primary source of heat is radioactivity….The major processes that heat the interiors of the terrestrial worlds are…

Heat deposited as the planets were built from planetesimals.
Heat deposited as the planets underwent differentiation.
Heat released by radioactive decay.

What are the two sources of internal heat for terrestrial planets?

Describe the three sources of internal heat of the terrestrial planets. Accretion is heat generated by the agglomeration of planetesimals when the planet was formed. Differentiation is heat generated by the energy released as dense objects fall toward the center of a planet during the formation of the core of a planet.

What are the two major requirements for the planet to become habitable?

Habitable Planets. A "habitable" planet should: Orbit a star that remains stable in output for billions of years. Be at a distance from the star that results in its achieving a suitable temperature so its surface water is liquid, not frozen.

What are the major processes at work on the terrestrial planets surfaces?

The four major geological processes are impact cratering, volcanism, tectonics, and erosion.

What is the most important process for producing the atmospheric gases around terrestrial planets?

volcanic eruptions Gases are vented (outgassed) through volcanic eruptions. The terrestrial planets must have been warmer and more volcanically active when they were younger. These gases will accumulate at the surface of the planet and in the atmosphere.

How do terrestrial planets gain internal heat?

In general, planets produce heat according to their size. Radioactive atoms decay in the interior, and conduction and convection transport this heat from the interior to the surface. Bigger planets have more gravity, and the pressure due to gravity helps to create a molten interior that can drive geological activity.

How do the interiors of terrestrial planets heat up?

Convection transports heat as hot material rises and cool material falls. Conduction transfers heat from hot material to cool material. Radiation sends energy into space. Smaller worlds cool off faster and harden earlier.

What are the three main heating sources for terrestrial planets?

Pressure, friction, and radiation.

What are the requirements for life on a planet?

It is useful to categorize the requirements for life on Earth as four items: energy, carbon, liquid water, and various other elements. These are listed in Table 1 along with the occurrence of these factors in the Solar System (2).

What are the factors that make a planet habitable?

7 features that make a planet habitable

Right distance from their star.
More or less circular orbit.
Stable rotational axis.
Some water, but not too much.
No hydrogen-rich atmosphere.
Plate tectonics.
Magnetic field.

What are the two primary sources of internal heat of the Earth?

There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements.

What heats the interior of terrestrial planets?

Currently the terrestrial planets' primary source of heat is radioactivity.

What are the 3 major heating processes for planetary interiors?

Radioactive decay is most important heat source today. Convection transports heat as hot material rises and cool material falls. Conduction transfers heat from hot material to cool material. Radiation sends energy into space.

What are the factors that make the planet habitable 2 What are the characteristics of planet Earth that makes it habitable?

What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.

Which of these are the two sources of Earth’s internal heat quizlet?

What are the sources of Earth's internal heat? The sources of heat inside the Earth are leftover heat from Earth's formation, and Radioactive decay.
