Continuous Supply of Fresh Water:

Physical Process: Water cycle (evaporation, condensation, precipitation) where water is evaporated from oceans, lakes, and rivers, forms clouds, and falls back to the Earth as rain, maintaining a continuous supply of freshwater.

Chemical Process: None specified, but water's chemical properties (H2O) remain consistent during the water cycle.

Rich Topsoil for Plants to Grow:

Physical Process: Natural weathering of rocks and minerals over time, erosion, and decomposition of organic matter contribute to the creation of nutrient-rich topsoil.

Chemical Process: Decomposition of organic matter (humus) releases nutrients into the soil, enriching its composition.

Materials for Building Houses:

Physical Process: Extraction of raw materials (wood, stone, metal ores, etc.) from the Earth's crust, followed by processing, refining, and manufacturing to create construction materials.

Chemical Process: Various chemical reactions might be involved in the extraction, refinement, and processing of raw materials.

Food Supply for Animals and People:

Physical Process: Plant growth through photosynthesis, which involves the conversion of sunlight, carbon dioxide, and water into energy-rich molecules, providing the basis of the food chain.

Chemical Process: Photosynthesis in plants involves complex chemical reactions that convert light energy into chemical energy.

Humus Adds Fertility to the Soil:

Physical Process: Accumulation of organic matter from decomposed plants and animals in the soil.

Chemical Process: Decomposition of organic matter releases nutrients and forms humic acids, which improve soil structure and nutrient retention.

Presence of Air Pollutants:

Physical Process: Emission of pollutants from various sources such as vehicles, industrial processes, and natural sources into the atmosphere.

Chemical Process: Reaction of pollutants with atmospheric components, leading to the formation of secondary pollutants and contributing to air quality degradation.

Greenhouse Effect:

Physical Process: Certain gases in the Earth's atmosphere (such as carbon dioxide, methane, and water vapor) trap heat from the sun, creating a natural warming effect.

Chemical Process: Interaction between greenhouse gases and infrared radiation leads to the retention of heat in the atmosphere.

Climate Change:

Physical Process: Alteration of the Earth's climate patterns over extended periods due to changes in temperature, precipitation, and atmospheric conditions.

Chemical Process: Increased greenhouse gas emissions and other human activities can contribute to changes in the chemical composition of the atmosphere, affecting climate.

Global Warming:

Physical Process: Gradual increase in the Earth's average surface temperature due to the enhanced greenhouse effect.

Chemical Process: Increased concentrations of greenhouse gases, primarily carbon dioxide, in the atmosphere contribute to trapping more heat.

Water and Land Pollution:

Physical Process: Discharge of pollutants (industrial waste, agricultural runoff, sewage) into water bodies and soil.

Chemical Process: Chemical contaminants from various sources can contaminate water and soil, affecting their composition and quality.
