Describe the process of evaporation in the water cycle. What factors can influence the rate of evaporation?

Evaporation is the process where liquid water changes into water vapor. Factors influencing it include temperature, humidity, and surface area.

Explain how condensation leads to the formation of clouds. What role does condensation nuclei play in this process?

Condensation occurs when water vapor cools and changes into liquid water or ice. Condensation nuclei (e.g., dust, salt) provide surfaces for water vapor to condense upon, forming clouds.

What are the different forms of precipitation? Describe the conditions that lead to each form.

Forms of precipitation include rain (liquid water), snow (ice crystals), sleet (rain that freezes as it falls), and hail (balls of ice). Conditions vary based on temperature profiles in the atmosphere.

Describe the process of collection in the water cycle. Where does collected water eventually go?

Collection refers to the accumulation of water in rivers, lakes, oceans, and groundwater. This water can then evaporate, starting the cycle again, or be used by living organisms.

How does the water cycle contribute to the distribution of heat around the Earth?

Evaporation absorbs heat, and condensation releases heat. This process transfers heat from warmer to cooler regions, influencing global climate patterns.
