Front

Model of the solar nebula and explanation of how the planets formed.

Back

The solar nebula model describes the formation of the solar system from a rotating disk of gas and dust. Planets formed through accretion of material in this disk.

Front

Role of gravity in the formation of the solar system.

Back

Gravity caused the collapse of the solar nebula, leading to the formation of the sun and planets. It also helped in the accretion of planetesimals into planets.

Front

Location of terrestrial, Jovian, and dwarf planets in the solar system.

Back

Terrestrial planets are located closer to the sun, Jovian planets are farther out, and dwarf planets can be found in various locations, including the Kuiper Belt.

Front

Characteristics of Jovian and terrestrial planets.

Back

Jovian planets are gas giants with thick atmospheres, while terrestrial planets are rocky with solid surfaces.

Front

Definition of eccentricity and meanings of e=0 and e=1.

Back

Eccentricity measures the deviation of an orbit from a perfect circle. e=0 indicates a circular orbit, while e=1 indicates a parabolic trajectory.

Front

Earth's tilt creates different seasons throughout the year by causing varying amounts of sunlight to reach different parts of the planet.

Back

The changing seasons are a result of this variation in sunlight.

Front

Spring Tide

Back

Higher high tides and lower low tides due to alignment of Earth, Sun, and Moon.

Front

Neap Tide

Back

Lower high tides and higher low tides due to Earth, Sun, and Moon forming a right angle.

Front

What is nuclear fusion?

Back

It is the process where hydrogen nuclei combine to form helium, releasing energy, in the sun's core.
