Land and Deforestation Flashcards
The degradation or destruction of earth’s surface and soil, directly or indirectly as a result of human activities
Soil Pollution
Causes of Land Pollution
- Degenerative Actions
- Misuse of Land
- Soil Pollution
- Land Conversion
Effects of Land Pollution
- Effects on Climate
- Bio Magnification
- Extinction of Species
The felling and clearing of forest cover or tree plantations in order to accommodate agricultural, industrial or urban use.
Deforestation
Causes of Deforestation
- Agricultural Activities
- Mining
- Urbanization
- Desertification
Effects of Deforestation
- Climate Imbalance
- Soil Erosion
- Floods
- Wildlife Extinction
The extraction ofvaluablemineralsor othergeological materials from the earth from anore body,lode,vein,seam, orreef, which forms the mineralized package of economic interest to the miner.
Mining
Philippine Mineral Reserves
Gold Copper Nickel Chromite Iron Bauxite Marble Limestone
Mining Disadvantages
- Habitat Destruction
- Acid Run-off from Mines
- Deforestation
The practice of tilling sloped land along lines of consistent elevation in order to conserve rainwater and to reduce soil losses from surface erosion.
Contour Farming
It is defined as alternating crop rows between heavy-rooted plants and loosely-rooted plants to minimize erosion.
Strip Cropping
Strip Farming
Method of growing crops on sides of hills or mountains by planting on graduated terraces built into the slope.
Terrace Cultivation
The one that has a critical role in determining and maintaining the overall relationships of plants and animals within an ecosystem.
Keystone Species
Includes a lot of human actions that affect the soil
Degenerative Actions
Mainly refers to cutting trees to clear land for agriculture
Misuse of Land
Converting a piece of fertile land into dessert-land or dry-land
Desertification
It os precisely during such conditions that man has to resort or measure such as deforestation and others to meet his needs
Inefficient Use of Land
Caused by wrong agricultural practices
Soil Pollution
When a piece of land is converted from its indigenous form to a form used for either agriculture or infrastracture
Land Conversion
Effect of land pollution that affects the rain
Effects on Climate
Process in which certain non-biodegradable substances go on accumulating in the food chain
Biomagnification
Species are pushed towards endangerment and extinction
Extinction of Species
Fragmentation of the natural habitat of an organism
Habitat Fragmentation
When land clearing adversely affects animals special such that their natural habitat is lost
Habitat Destruction
