How would the absence of gravity affect the formation of planets quizlet?
How would the absence of gravity affect the formation of planets? A. The rocks and debris would take longer to accrete into a planet.
What role does gravity play in the formation of the sun?
What role did gravity play in forming the sun? Gravity caused the solar nebula to collapse toward the center, causing the center of the sun to be dense and hot. What type of surface to terrestrial planets have?
What were the steps in the formation of the planets?
Two processes are important in planet formation. Condensation is the production of solid dust grains as gases in the molecular cloud cool, and accretion is the collision of the dust grains to form clumps and progressively larger bodies, some of which grow into planets (Figure 10.2).
How do Jovian planets form?
The jovian planets, however, formed farther from the Sun where ices and rocks were plentiful. The cores accreted rapidly into large clumps of ice and rock. Eventually, they got so large, they captured a large amount of hydrogen and other gasses from the surrounding nebula with their enormous gravity.
What is the purpose of other planets?
The other planets, meaning the ones visible to our eye, help us in drawing a sky map while the ones that are barely visible, Neptune and Uranus, do not hold that much of an importance.
Which object in our solar system has the greatest gravitational force Why?
The Sun
What has the greatest gravitational force in our solar system?
Jupiter
Where is gravity the strongest on earth?
The effect of Earth’s gravity is stronger, the closer you are to the centre of gravity, roughly the centre of the earth. So the gravitational effect will be slightly weaker at the equator than at the poles. And of course at the top of a mountain on/near the equator, slightly weaker again.
What is the value of G maximum and minimum?
The centrifugal force for the spinning of earth is maximum at the equator and vanishes at the poles. Thus, the gravitational acceleration (g) is minimum at the equator and it is maximum at the poles.
What is the value of g in minimum?
Its radius is maximum at the equator. Hence according to equation g = GM/R2 , the equator is the place where g will be minimum….Thank you.

What is the smallest value of g?
The value of ‘g’ is minimum at the equator because earth is not a perfect sphere. Its radius is maximum at the equator. Hence, according to the equation g = GM/R2, the equator is the place where g will be minimum.
What role did gravity play in the formation of the sun quizlet?
What role did gravity play in forming the sun? Gravity caused the solar nebula to collapse toward the center, causing the center of the sun to be dense and hot.
Which claim describes the role gravity played in the formation of the sun?
Which claim describes the role gravity played in the formation of the sun? Gravity caused the protoplanetary disk to become a planetesimal, which became the sun. Gas giants contain ices because these planets formed far enough from the sun that these materials could condense.
What holds our solar system together?
The Sun is a yellow dwarf star, a hot ball of glowing gases at the heart of our solar system. Its gravity holds the solar system together, keeping everything – from the biggest planets to the smallest particles of debris – in its orbit.
What best describes the formation of our solar system?
Formation. Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material.
How the solar system was formed step by step?
Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump together.
What can we learn about the formation of our solar system by studying other stars explain?
Explain. Observing other stars allows us to see that different types of planets and planet formation begins in the same location. Observing other stars can also help us understand how planets formed in systems with stars similar to our own Sun by observing the many stages those stars go through.
What is the name of our solar system?
Our planetary system is named the “solar” system because our Sun is named Sol, after the Latin word for Sun, “solis,” and anything related to the Sun we call “solar.” Our planetary system is located in an outer spiral arm of the Milky Way galaxy.
What is each planet made of?
Earth and the other three inner planets of our solar system (Mercury, Venus and Mars) are made of rock, containing common minerals like feldspars and metals like magnesium and aluminum. So is Pluto. The other planets are not solid. Jupiter, for instance, is made up mostly of trapped helium, hydrogen, and water.
What is the closest solar system to us?
Alpha Centauri
Is traveling through a wormhole possible?
Physicists have worked out a way that it might be feasible to send someone through a wormhole. Wormholes are tunnels between two black holes that connect distant regions of space-time, and normally it would be impossible to pass something through them, but factoring in an extra dimension might make it possible.
What exists in between galaxies?
Gas called the intergalactic medium fills the space between galaxies; the gas of the circumgalactic medium surrounds galaxies more closely. The gas in both places regulates the birth, life and death of the galaxies, and holds a detailed history of the universe. Only lately have astronomers been able to detect it.
Can a planet exist outside a galaxy?
An extragalactic planet, also known as an extragalactic exoplanet, is a star-bound planet or rogue planet located outside of the Milky Way Galaxy. Due to the huge distances to such worlds, they would be very hard to detect directly. However, indirect evidence suggests that such planets exist.
Why is space dangerous?
The environment of space is lethal without appropriate protection: the greatest threat in the vacuum of space derives from the lack of oxygen and pressure, although temperature and radiation also pose risks. The effects of space exposure can result in ebullism, hypoxia, hypocapnia, and decompression sickness.
