Compare and contrast the conditions required for snow and rain to form.

Answers

Answer:

Snow forms when the atmospheric temperature is at or below freezing, and there is a minimum amount of moisture in the air. Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain

Explanation:

When water vapor cools and condenses forms clouds, that is, return to water or rain.

When the temperature in the atmosphere is at or below freezing 0 degrees Celsius and there is a minimal amount of moisture in the air, snow forms.

How does rain form?

Clouds are formed by evaporating water or ice from the Earth's surface, or by plants releasing water and oxygen as a result of photosynthesis.

Water evaporates, or rises from the Earth's surface into the atmosphere, creating a gas called water vapor.

When water vapor cools and condenses—that is, returns to liquid water or ice—it forms clouds.

How does snow form?

A significant snowstorm or blizzard requires three factors:

Cold air (below freezing).Clouds and precipitation require moisture to form.Clouds and snow form when moist air rises over very cold air.

Thus, these are the conditions for snow and rain.

Sahil watched a demonstration in which a scientist combined two substances in a sealed container and analyzed the results. The ending substances did not look the same as the starting substances.Sahil was given a diagram with the repeating groups of atoms that make up the starting substances, plus information about the properties of the starting and ending substances. He created a model of the repeating groups of atoms that might make up the two ending substances.Does his model correctly show why the properties of the ending substances are different from the properties of the starting substances? Describe what could be correct or incorrect about his model.

Answers

This model correctly show the chemical reaction that take place in this model.

Is this model show correctly the process?

This model correctly show the properties of the ending substances that are different from the properties of the starting substances because the properties of product are different from the reactants.

So we can conclude that this model correctly show the chemical reaction that take place in this model.
