Answer: Clouds are evaporated sea water. You should be asking "Why does the gravity on Earth pull us down and not evaporated water.
Explanation:
Answer:
Because of their mass
Explanation:
Clouds are made of water right ? so you are asking why they don't fall down if air is lighter than water .
The two biggest reasons the clouds stay in the sky are
1. Small Drops
2. Wind
Small drops of water fall more slowly than big drops, as the drops of the clouds fall thought the air, the air pushes back to them, because Small drops has less mass than large drops, clouds can only contain small drops of water.
The four most common gases in dry air are nitrogen, oxygen, carbon dioxide, and water vapor.
The four most common gases in dry air are nitrogen, oxygen, carbon dioxide, and water vapor.
Nitrogen is the most abundant gas in dry air, making up about 78.6% of the air.
Oxygen is the second most abundant gas, accounting for approximately 20.9% of the air.
Carbon dioxide is present in small amounts, around 0.04%, but it plays an important role in the Earth's carbon cycle and climate. Water vapor, despite being a variable component, can make up around 0.5% of the air.

Explanation:
In an exothermic reaction, heat is released into the surroundings. In this type of reaction, energy of products is less than the energy of reactants.
In an endothermic reaction, heat is absorbed by the reactant molecules. In this type of reaction, energy of products is more than the energy of reactants.
Therefore, we can conclude that while performing an experiment involving a reaction between two chemicals, the scientist observes that the reaction container has become warm. The observation is an example of exothermic reaction.
Answer:
Acceleration = 20 m/s2
Further explanation:
16 N = 0.80 kg x acceleration
Acceleration = 20 m/s2
