Short Answer:
buoyancy
Long answer:
An object submerged in water displaces water according to how much it weighs. In fact, the water will push upward against the object with a force equal to the weight of the water it displaces. For example, a bowling ball and a beach ball that are the same size will have the same volume. The bowling ball, however, is more massive and thus denser than the beach ball. In both cases, the water pushes up against the ball with a force equal to the weight of water it displaced. In the case of the bowling ball, it weighs more than the amount of water it displaced, so it sinks. The beach ball, however, displaces very little water and the air inside it is much lighter than the weight of the water it displaced, so it floats.When lifting something underwater, you have the help of water pushing the object upwards along with your own strength, which is why it's easier to pick up things underwater than on land.

They all existed as a single continent called Pangea. Pangea first began to be torn apart when a three-pronged fissure grew between Africa, South America, and North America.
Answer:
11 time zones
Explanation:
Russia is the largest country in the world. The country is generally stretched by longitude, so it is no wonder that it has numerous times zones. To be more precise, Russia has eleven time zones out of the twenty four time zones, so almost half of them.
The eleven time zones in Russia are named locally and they are:
- Kaliningrad Time
- Moscow Time
- Samara Time
- Yekateriburg Time
- Omsk Time
- Krasnoyarsk Time
- Irkutsk Time
- Yakutsk Time
- Vladivostok Time
- Magadan Time
- Kamchatka Time
The Moscow Time is taken as central time, as Moscow is the center of Russia in many aspects, and plus this time zone occupies the area where the majority of the population lives and the majority of the industry is located.
Kaliningrad is the westernmost time zone, also occupying the least territory, while Kamchatka is the easternmost time zone where the Sun first rises in Russia.
