When a planetary nebula gravitationally contracted to form our solar system what caused the central region to rotate faster and flatten into a plane?

When a planetary nebula gravitationally contracted to form our solar system what caused the central region to rotate faster and flatten into a plane? The conservation of angular momentum.

What observation suggests our solar system formed from a gravitationally contracting gas cloud?

What observation suggests our Solar System formed from a gravitationally contracting gas cloud? he consistent ages of the planets, asteroids, and the Sun.

What happens when a solar nebula contracts?

Nebular Theory: Our solar system evolved from a contracting nebula. Under the influence of its own gravity, the nebula contracts. As it contracts, it spins faster and faster, much like an ice skater who pulls in her arms. This effect is known as conservation of angular momentum.

Which law of physics explains why the nebula formed the solar system begin to rotate faster as it collapsed?

What physical law explains why a cloud will rotate rapidly as it collapses? The nebular theory also predicts that the cloud should heat up as it collapses.

Which physical Conservation Law explains the formation mechanism of the solar system in the nebular theory?

Conservation of angular momentum rotational motion is conserved Our Solar System formed from a giant, swirling cloud of gas & dust. The nebular theory holds that our Solar System formed out of a nebula which collapsed under its own gravity.

Edexcel GCSE (9-1) Astronomy, Topic 8: Planetary Motion and Gravity (summary)

What force causes the nebula to begin to contract?

A nebula (gas cloud) slowly contracts under the mutual gravity of all of the atoms in the cloud.

How was the solar system formed nebular theory?

The nebular theory states that our solar system formed from the gravitational collapse of a giant interstellar gas cloud—the solar nebula. – (Nebula is the Latin word for cloud.) Kant and Laplace proposed the nebular hypothesis over two centuries ago. A large amount of evidence now supports this idea.

What caused the solar nebula to rotate?

Heavier elements sank to the center, forming iron-rich cores. Lighter materials were buoyed upward to form the outer rocky layers. The slowly rotating solar nebula collapsed under its own gravity to form a rapidly rotating disk, with the Sun at the center.

What causes a solar nebula to initially form a solar system?

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 causes nebula to spin?

The primary source of spin in nebulae (also for galaxies), is torque from the local environment. Nearby nebulae, clouds, stars, etc can exert a net torque on the nebula (or galaxy) giving it angular momentum. This is the primary source of spin for nebulae.

What happens to the shape of a nebula as it contracts and spins faster?

What happens to the shape of a nebula as it contracts and spins faster? As a nebular contracts and spins faster it flattens out into a disc.

What is nebular contraction?

Page 13. Nebular contraction: Cloud of gas and dust contracts due to gravity; conservation of angular momentum means it spins. faster and faster as it contracts.

What happens as a rotating gas cloud contracts?

As a rotating gas cloud contracts, it spins faster. In the solar nebular theory, the dusty disk condensing around the Sun's equator became the ecliptic plane in which the planets then formed. In addition to revolving around the Sun counter clockwise, most planets also rotate on their axis counter clockwise.

What caused the planets to heat up during the early formation of the solar system?

Why was the earth so hot when it formed? Gravitational contraction/accretion: gravity caused small bodies of rock and metal orbiting the Sun to smash together. These collisions caused temperatures and pressures to increase.

How did our solar system begin to form quizlet?

The solar system formed 4.6 billion years ago from a swirling, disk-shaped cloud of gas, ice, and dust, called the solar nebula.

Which force was mostly responsible for the contraction of the gas cloud?

I. Contraction of insterstellar cloud. Solar system formed about 4.6 billion year ago, when gravity pulled together low-density cloud of interstellar gas and dust (called a nebula)(movie).

How is the solar nebula theory supported by the motion of solar system bodies?

How is the solar nebula theory supported by the motion of solar system bodies? All of the planets orbit the sun near the sun's equatorial plane. All of the planets orbit in the same direction that the sun rotates. Six out of seven planets rotate in the same direction as the sun.

Why did the solar nebula heat up as it collapsed quizlet?

Why did the solar nebula heat up as it collapsed? As the cloud shrank, its gravitational potential energy was converted to kinetic energy and then into thermal shock.

What is the solar nebula quizlet?

The solar nebula is the cloud of gas from which our solar system was born when it collapsed under its own gravity. By using the compositions of the Sun, other stars, and interstellar gas clouds, we know that the solar nebula contained 98% hydrogen and helium and only 2% of all other elements combined.

How the nebula are formed?

They either form through clouds of cold interstellar gas and dust or through the aftermath of a supernova. For example, in the Carina Nebula, hot, young stars erode and sculpt the clouds into this fantasy landscape by sending out thick stellar winds and scorching ultraviolet radiation.

How did the earth become round?

The Short Answer:

A planet is round because of gravity. A planet's gravity pulls equally from all sides. Gravity pulls from the center to the edges like the spokes of a bicycle wheel. This makes the overall shape of a planet a sphere, which is a three-dimensional circle.

What is the nebular hypothesis quizlet?

Theory that believes that all bodies in our solar system evolved from an enormous rotating cloud called the solar nebula.

What forms at the center of the rotating disk in a nebula?

The Sun formed from material that condensed in the center of the spinning disk. The nebula also began to spin counterclockwise, as it conserved the angular momentum of the material drawn toward the center. This spinning made the material around the center of the condensing nebula flatten out into a disk-like shape.

Why would the nebula begin to contract shrink?

As a ball of dust and gas contracts under its own gravity, it begins to shrink and its core begins collapsing faster and faster. This causes the core to heat up and to rotate. At this stage, the condensed material is called a protostar.

What is a spinning nebula?

The nebular hypothesis is the idea that a spinning cloud of dust made of mostly light elements, called a nebula, flattened into a protoplanetary disk, and became a solar system consisting of a star with orbiting planets [12].
