We weren't there to watch, but yes, that's how we think it started out. There is some debate about why a cloud of gas and dust should collapse to form a solar system. At least one theory suggests that there may have been a "nearby" supernova explosion 5-6 billion years ago, and the shock wave might have started the collapse. And since we're certain that our solar system is at least a 3rd generation star (since our Earth contains heavy elements like lead and gold, that could ONLY be produced in supernova explosions), that supernova may have also contributed substantial amounts of mass that went into making up "US", in addition to causing the nebular coalescence.
The Sun.
The Earth formed about 4.5 billion years ago from a cloud of dust and gas in space, a remnant of the solar system's formation from a nebula. Gravity caused the cloud to collapse, forming the Sun at the center and the planets, including Earth, from the remaining material in orbit around it.
gravity
Gorges are formed by tectonic plate movement or by erosion caused by flowing water-rivers.
Planets are round due to gravity pulling material towards their center, which results in a spherical shape. This is known as hydrostatic equilibrium, where gravity balances the internal pressure caused by the material pushing outwards. Over time, this gravitational force molds planets into the most energy-efficient shape, which is a sphere.
The hydrogen in the Sun has nuclear energy (a type of potential energy). When this is fused, it is converted to heat energy. This eventually gets radiated out as light energy.
Energy is formed through processes such as photosynthesis in plants, where sunlight is converted into chemical energy. It is also formed through the combustion of fossil fuels, where chemical energy stored in the fuels is released as heat and light energy. In nuclear reactions, energy is formed by splitting atoms (fission) or fusing atoms together (fusion).
Electrical energy can be formed by solar, wind or hydro energy. This energy is transformed into electrical energy.
The center of gravity of the truck
No. It requires energy to break bonds, but energy is released when bonds are formed.
Earth is layered due to gravitational compression that caused dense materials to sink onto the Earth's center, while the less dense materials rose.
It is caused by desertifacation.
a proton
Marrow.
it is a wave that is formed by energy
potential
The sun formed from a large cloud of gas and dust in space about 4.6 billion years ago. As gravity caused the cloud to collapse, it heated up and formed the sun at the center, while the remaining material in the cloud eventually formed the planets in the solar system.
