What are the 4 stages of planetary development?
After becoming distinct planets, they went through four stages of formation: Differentiation, Cratering, Flooding and Surface Evolution.
What is the first stage of planetary development quizlet?
The first stage of planetary evolution is cratering. Most of Earth’s history has been destroyed by an active crust and erosion.
Why are almost all the craters we see on the moon circular quizlet?
What are the similarities and differences between Moon and Earth rocks? … Why are almost all of the craters on the moon circular, even though many impacts were not head-on? Because the fast moving debris was vaporized before colliding with the Moon’s surface. 18.
How does the formation of the Hawaiian Emperor island chain help in the understanding of tectonics quizlet?
(b) How does the formation of the Hawaiian-Emperor island chain help in the understanding of tectonics? Motion of the Pacific plate allowed volcanic hot-spots to punch through the crust. It is an example of tectonics and volcanism working together to form mountains.
What are the 4 solar systems?
Of the bodies that orbit the Sun directly, the largest are the four gas and ice giants and the four terrestrial planets, followed by an unknown number of dwarf planets and innumerable small Solar System bodies.
|Known planets||8 declared by IAU: Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune|
What is the planetary process?
In planetary science, planetary differentiation is the process of separating out the different components within a planetary body as a consequence of their physical or chemical behavior (e.g. density and chemical affinities).
What is the first stage of planetary development?
The first stage of planetary development is called differentiation, the settling of dense material, like iron-rich minerals, into the center of a planet and the rising of less dense material, such as silicon-rich minerals, to the surface of one.
What is the correct textbook order of planetary development?
A newly-formed terrestrial planet, such as the Earth or Venus, goes through four distinct stages of development: Differentiation, Cratering, Flooding and Surface Evolution.
During which stage of planetary development did the lunar maria form?
The maria basins were formed beginning about 3.9 billion years ago during a period of intense bombardment by asteroid-sized bodies. This was well after the lunar crust had cooled and solidified enough, following the Moon’s formation, to retain large impact scars.
What is maria on moon quizlet?
Maria are the large, smooth, dark areas of the Moon’s surface. They have few craters. This is a Latin word for “seas” (think of mare). These regions, like most of the Moon, are devoid of water.
Which of the following characteristics do the four terrestrial planets have in common?
Which of the following characteristics do all four terrestrial planets have in common? They all have solid surfaces with signs of geological activity on them. Of the following planets, which one does NOT have satellites (moons)? … It was so hot where the inner planets formed that the lighter materials evaporated.
What does the Moon not have?
Just as the discovery of water on the moon transformed our textbook knowledge of Earth’s nearest celestial neighbor, recent studies confirm that our moon does indeed have an atmosphere consisting of some unusual gases, including sodium and potassium, which are not found in the atmospheres of Earth, Mars or Venus.
How was the Hawaiian Emperor island chain formed quizlet?
The Hawaiian Islands were formed by volcanic activity. The Hawaiian Emperor seamount chain is a well-known example of a large seamount and island chain created by hot-spot volcanism. Each island or submerged seamount in the chain is successively older toward the northwest.
How do island chains located in the centers of tectonic plates such as the Hawaiian Emperor chain indicate ongoing plate tectonic activity?
How do island chains located in the centers of tectonic plates, such as the Hawaiian-Emperor chain, indicate ongoing plate tectonic activity? The chains demonstrate the motion of the plate over an upwelling lava source. As the plate moves, the lava sequentially breaks through, creating a chain of islands.
What methods do astronomers use to detect exoplanets?
The main techniques used to detect exoplanets are:
- Direct imaging: The exoplanet is imaged directly using large telescopes fitted with adaptive optics and coronagraphs. …
- Radial velocity: …
- Transits: …
- Microlensing: …
- Transit timing variations:
