Front

What is condensation?

Back

Condensation is the process by which water vapor in the air is changed into liquid water. An example is water drops forming on the outside of a cold water bottle.

Front

What nutrient is essential for the growth of plant parts above ground?

Back

Nitrogen is essential for the growth of plant parts above ground as it is a key component of chlorophyll, which plants use in photosynthesis.

Front

What is evaporation?

Back

Evaporation is the process by which liquid water turns into water vapor. This process occurs when water is heated and molecules gain enough energy to escape into the air.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs sunlight, which is necessary for photosynthesis, allowing plants to convert light energy into chemical energy.

Front

What is a major cause of excess carbon in the atmosphere?

Back

Fossil fuel usage for electricity generation is a major cause of excess carbon in the atmosphere, contributing to climate change.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, primarily converting carbon dioxide and water into glucose and oxygen.

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 is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, including rain, snow, sleet, and hail.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere, which can lead to climate change.

Front

What is the significance of potassium for plants?

Back

Potassium is significant for plants as it helps regulate various physiological processes, including water uptake, enzyme activation, and photosynthesis.
