Science - Flashcard 2

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes like evaporation, condensation, and precipitation.

Front

What do plants need for photosynthesis?

Back

Plants need water, sunlight, and carbon dioxide to perform photosynthesis, which is the process of converting light energy into chemical energy.

Front

Why does the sky appear blue during the day?

Back

The sky appears blue because of the scattering of sunlight by the atmosphere, which scatters shorter blue wavelengths of light more than other colors.

Front

What properties can describe a flower?

Back

A flower can be described by its color and odor, which are important characteristics that help in identifying different types of flowers.

Front

What is a characteristic of mammals?

Back

A characteristic of mammals is that they have fur or hair, which helps to keep them warm.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, usually due to heat.

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air cools and changes back into liquid water, forming clouds.

Front

What is precipitation?

Back

Precipitation is any form of water, such as rain, snow, sleet, or hail, that falls from the atmosphere to the Earth's surface.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the atmosphere?

Back

The atmosphere is the layer of gases surrounding the Earth, which is essential for life and plays a key role in weather and climate.
