The closer a planet is to the Sun, the FASTER its orbital motion is, and the STRONGER gravitational force between the planet and the Sun is.
Radiation occurs when energy moves through space, such as heat or light from the sun. There are multiple types of radiation, but all involve energy travelling away from a source.
When energy travels through space, it is known as radiation. There are different types of radiation, but they all involve forms of energy moving through space. For instance, light and heat from the sun travel through the vacuum of space to reach the earth. This is an example of electromagnetic radiation. Other forms include alpha, beta, and gamma radiation. These all entail particles or waves moving away from a source and travelling through space.

Sharks have some fascinating features which make these animals to be best adaptable to live in an aquatic environment and also for hunting.
Some of the physiological features include:
1) The skeletons of sharks is not made up of bones, rather it is made up of cartilages. This makes the skeletons of sharks lighter and more flexible.
2) The esophagus of sharks is short but wide which makes it adaptable for swallowing smaller preys. It also allows the larger preys to be gulped down.
3) A shark eats only about 5% of its body weight per week. It can survive without food for many days due to its slow metabolism.
