QUARTER 2 Flashcards
This is generated and disposed of in great amounts by people all over the world. These end up in landfills and become a source of pollution.
Solid Waste
Includes trash or garbage from households, schools, offices, marketplaces, restaurants, and other public places.
Municipal solid waste
Produced from health care facilities such as hospitals, clinics, veterinary facilities, and laboratories.
Medical and clinical wastes
These are generated by agricultural activities such as plant cultivation, fruit growing, seed growing, livestock breeding, vegetable gardening, and seedling banks.
Agricultural wastes
Comes from manufacturing various products like glass, leather, textile, food, electronics, plastic, and metal products that are generated in bulk.
Industrial wastes
Results from the construction of roads and buildings. Old houses or buildings are demolished to build new ones.
Construction and demolition wastes
From electronic and electrical devices includes DVD and music players, TVs, telephones, computers, vacuum cleaners, and all the other electrical appliances at home.
Electronic waste
This is defined as any waste in liquid form such as fluids from wastewater; fats, oils and grease, and any other hazardous household liquids.
Liquid Waste
Often referred to as domestic wastewater that results from daily activities such as cooking, washing, bathing, and toilet use.
Liquid wastes from residential areas
Generated by processing or manufacturing industries and service industries, such as car repair shops. Also from food product manufacturing companies, dairy waste, and from all cisterns within the industrial facilities.
Liquid wastes from industries
Caused by the seepage of rainwater through the deposited material in landfills.
Landfill leachate
Oxides or carbon, sulfur dioxide, oxides of nitrogen, hydrocarbons, aerosols, carbon monoxide, methane, and greenhouse gases like chlorofluorocarbon.
Gaseous wastes
Hazardous gas emitted from landfills. They attract insects and bugs.
Methane
Solid wastes pose a significant risk to water and quality and can be a source of toxic contaminants.
Water Contamination
When the condition of the landfill worsens and the community becomes intolerant of such condition, the landfill is transferred farther from densely populated areas.
Energy Consumption
A land that is claimed for landfill is no longer viable to many plants and wildlife.
Natural Habitat Degradation
This is the rapid growth in the population of bacteria and algae in rivers and lakes known as algal bloom.
Eutrophication damage
Poses a serious threat to an ecosystem. Waste deposited directly into bodies of water negatively changes the chemical composition of water.
Surface water contamination
Can affect the health of most living things. Hazardous chemicals that get into the soil can harm plants when they absorb the contaminants through their roots.
Soil contamination
Can be hazardous if it enters the surface water, groundwater, and soil.
Leachate
Causes people to be at risk of getting sick due to bacteria and viruses by bathing in polluted waters.
Bathing in contaminated water reservoirs
Can cause different problems to a person’s health. Shellfish filter water through their gills to trap microscopic pants and animals for their food.
Contaminated shellfish
Certain fish in contaminated waters can accumulate high levels of toxic substances.
Contaminated fish
Can cause liver and kidney damage.
Detergents
Carries disease-causing organisms, leading to infection of the small intestine, amoebic dysentery, and cholera.
Sewage water
Creates harmful emissions such as carbon dioxide and sulfur when it is burned.
Biomass
Is often added to gasoline since their combination burns cleaner than pure gasoline.
Ethanol
Gives off less sulfur oxide, particular matter, carbon monoxide, and hydrocarbons when burned than conventional petroleum diesel.
Biodiesel
Methane and carbon dioxide make up 90 to 98% of landfill gas. Landfill gas can move from a landfill through soil and to air outside or inside a building
Landfill gas
Weathering, erosion, sedimentation, and mass wasting are called?
exogenic process
The breaking down of ricks and other materials on the earth’s surface.
Weathering
This occurs when rocks break into pieces without changing their CHEMICAL composition.
Mechanical weathering
This occurs when the chemical composition of rocks are changed due to the ACTION of other substances.
Chemical weathering
This breaks rocks because of the changes in temperatures.
Temperature
The repeated changes in temperature cause the surface of the rocks to peel off.
Exfoliation
A unique property of water is that it expands when it freezes.
Frost Action
This is the wearing off of rocks by solid particles carried by wind, water, and other agents.
Abrasion
This changes the mineral content and the chemical composition of rocks.
Chemical Weathering
Almost all chemical weathering is due to the action of water. It can form acids when it combines with some of the gases in the air.
Water
This combines with other substances to form entirely new substances.
Oxygen
Soil remains on top of its parent rock or the rock form which it was formed.
Residual soil
When the soil is moved to other places by wind, water, glaciers, and waves on other land.
transported soil
the parent rock beneath the residual and transported soils.
bedrock
The product of weathering is carried away by erosion to other places.
Soil
Process in which soil and weathered rocks are transported from one place to another.
Erosion
Eroded rocks and soil are deposited in other places through a process called?
deposition or sedimentation
The most active agent of erosion.
Wind
These are mounds that are built by wind consisting of loose sand.
Dunes
A deposit of fine sand and silt.
Loess
This constantly erode and shape shorelines.
Waves
Consists of fine sand or large pebbles that are carried by waves to the shoes of the sea.
Beaches
Submerged or partly exposed ridges of sand and coarse sediments.
Sandbars
One of the major agents of erosion.
Running water
Rainwater that flows on the surface towards river streams.
runoff
U-shaped body of water that forms when a river fins a different, shorter course
oxbow lake
fan-shaped deposit of gravel, sand, and even smaller pieces of sediment.
alluvial fan
A landform created by the deposition of sediments carried by a river as the stream flows to a lake or an ocean.
delta
A flat area of land close to a river or stream.
floodplain
a natural wall that blocks the flow of water
levee
This erode surfaces through abrasion.
Glaciers
the accumulation of dirt and rocks that have fallen onto glacier surfaces.
moraine
