Exogenic Processes
100

This layer of soil, rich in organic material and nutrients, is vital for plant growth and is often the most fertile.

Topsoil

100

This type of freshwater, stored in underground aquifers, is accessed by wells and provides drinking water for millions worldwide.

Groundwater

100

This type of ecosystem service includes resources like food, water, and timber that humans use directly.

Provisioning Services

100

Signed by President Gloria Macapagal-Arroyo in 2001, this act mandates the establishment of a National Solid Waste Management Commission to address solid waste issues.

R.A. 9003

100

This exogenic process, involving the breakdown of rocks at Earth’s surface through mechanical, chemical, or biological means, is the first step in soil formation.

Weathering

200

This process, caused by wind and water, wears away soil particles and reduces soil fertility.

Soil Degradation

200

In this stage of the water cycle, water changes from gas to liquid, forming clouds.

Condensation

200

This human activity, involving the removal of trees for land use or lumber, contributes to habitat loss and increased carbon dioxide in the atmosphere.

Deforestration

200

Enacted in 2004, this law, signed by President Gloria Macapagal-Arroyo, aims to protect and manage the country's water resources, especially focusing on water quality and pollution control.

R.A. 9275


200

This type of weathering occurs when rock is physically broken down without changing its chemical composition, such as through freeze-thaw cycles.

Mechanical Weathering

300

Farmers plant cover crops like clover to prevent erosion and improve this important soil property.

Soil Fertility

300

This type of pollution occurs when rainwater carries pesticides and fertilizers from farms into rivers and lakes.

Salinity Changes

300

Waste like plastic bags and Styrofoam, which doesn’t decompose easily, falls under this category of waste.

non-biodegradable waste

300

Signed into law by President Joseph Estrada in 1999, this act sets regulations to maintain air quality and reduce air pollution across the Philippines.

R.A. 8749

300

This exogenic process, powered by wind, water, and ice, involves the removal and transportation of weathered materials from one location to another.

Erosion

400

This layer, located below the topsoil, contains minerals leached from above and is sometimes called the subsoil.

B - Horizon

400

This United Nations organization leads global efforts to ensure safe drinking water and sanitation for all.

UNEP

400

This "R" encourages finding new ways to use items rather than disposing of them, to reduce waste.

Reuse

400

Signed by President Corazon Aquino in 1991, this law regulates the disposal of toxic and hazardous waste in the Philippines.

R.A. 6969

400

This type of exogenic process involves the downslope movement of soil and rock due to gravity, including landslides and rockfalls.

Mass Wasting

500

This practice involves alternating crops in the same area each season to replenish nutrients in the soil.

Crop Rotation

500

This Law provides actions to take care of the Philippine Water Resources

R.A 9275 of 2004

500

This category of ecosystem services involves natural processes, such as pollination and water purification, that support life on Earth.

Regulating Services

500

Enacted in 1977 and signed by then-President Ferdinand Marcos, this Presidential Decree requires an Environmentally Critical Areas (ECA's) for projects that could harm the environment.

P.D. 1586

500

In this type of chemical weathering, minerals in rocks react with water, dissolving them and changing the rock composition.
