Gravity is the attraction between two objects that have mass or energy. The weak force, also called the weak nuclear interaction, is responsible for particle decay. This is the literal change of one type of subatomic particle into another. The electromagnetic force, also called the Lorentz force, acts between charged particles, like negatively charged electrons and positively charged protons. The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. And that's because it binds the fundamental particles of matter together to form larger particles.

Terrestrial planets are smaller, closer to the Sun and formed from rock around a molten metal core. Also, terrestrial planets have secondary atmospheres, fewer moons, and they rotate slower. On the other hand, Jovian planets are larger, further from the Sun and formed from gases around a solid metal and hydrogen core, and jovian planets rotate faster.

There isn't only a chance, there most likely is based on how big our galaxy alone is, and how our solar system is just smaller than a dot compare to it. There might even be billions of solar systems in our galaxy so much more in the whole universe which is always expanding.

The standard definition for a habitable planet is one that can sustain life for a significant period of time. As far as researchers know, this requires a planet to have liquid water. To detect this water from space, it must be on the planet's surface. We also need oxygen, a strong magnetic feild to protect us from solar flares, proper distance away from the sun, and lastly a atmosphere.

A planet is considered to be habitable if it can support life for an extended period of time. According to research, it's necessary to a planet to have liquid water. This water must be on the planet's surface in order to be seen from space. Last but not least, it require to have an atmosphere, oxygen, a strong magnetic field to shield us from solar flares, and a suitable distance from the sun.

Photons, a particle of light or other electromagnetic radiation, collided with another photon to form matter and antimatter, and vice versa. Particle-antiparticle pairs were created out of the radiation field, and then as soon as they were created, they mutually annihilated into radiation again. And all the antimatter and matter that were in equal proportions annihilated with each other. Hence, for every one billion protons and antiprotons that annihilated each other creating photons, a single proton was left over.

A biogeochemical cycle is a type of circular pathway through which matter moves or is recycled in an ecosystem. It includes geological, chemical and biological parts of the system. One of example is Water Cycle or Hydrologic Cycle, In this cycle a water from the transpiring plants, oceans, rivers and lakes evaporates into the atmosphere. These water vapours subsequently cool and condense to form clouds and water, and then the water returns to the earth as rain and snow.

Rocks and minerals are all around us! They help us to develop new technologies and are used in our everyday lives. Our use of rocks and minerals includes as building material, cosmetics, cars, roads, and appliances. In order to maintain a healthy lifestyle and strengthen the body, humans need to consume minerals daily.
