1
New cards

Ionizing Radiation

Energy capable of dislodging electrons from atoms, leading to ion formation and potential cancer risk (e.g., gamma, X-rays, UV).

2
New cards

High Quality Energy

Concentrated energy suitable for performing work efficiently (e.g., fossil fuels, nuclear energy).

3
New cards

Low Quality Energy

Dispersed and disorganized energy forms (e.g., heat in oceans, wind, solar).

4
New cards

First Law of Thermodynamics

Energy is conserved and can be converted from one form to another (Law of Conservation of Energy).

5
New cards

Second Law of Thermodynamics

Energy conversions result in the degradation of useful energy into lower quality forms, often heat.

6
New cards

Natural Radioactive Decay

Unstable isotopes release gamma rays, alpha and beta particles (e.g., Radon).

7
New cards

Half-Life

Time for half the mass of a radioactive isotope to decay.

8
New cards

Nuclear Fission

Splitting of isotope nuclei by neutrons.

9
New cards

Nuclear Fusion

Fusion of light element isotopes at high temperatures to form heavier nuclei (e.g., H to He).

10
New cards

Ore

Rock with profitable mineral concentrations for mining.

11
New cards

Mineral Reserve

Identified and profitable mineral deposits for extraction.

12
New cards

Best Solution To Energy Shortage

Conservation, efficiency increase, and exploration of alternative energy sources.

13
New cards

Organic Fertilizer

Slow-acting and long-lasting due to organic decomposition time.

14
New cards

Surface Mining

Cost-effective method for mineral extraction with lower worker hazards.

15
New cards

Humus

Dark organic material post-microorganism decomposition.

16
New cards

Leaching

Dissolved material removal from soil by downward water movement.

17
New cards

Illuviation

Leached material deposition in lower soil layers (B Horizons).

18
New cards

Loam

Optimal agricultural soil mix with sand, silt, clay in proportions (40%, 40%, 20%).

19
New cards

Soil Conservation Methods

Techniques like conservation tillage, crop rotation, and organic fertilizers.

20
New cards

Soil Salinization

Salt accumulation in arid regions due to water evaporation.

21
New cards

Conservation

Responsible resource use.

22
New cards

Preservation

Protection of areas from human activities.

23
New cards

Water Logging

Soil saturation leading to plant root oxygen deprivation.

24
New cards

Hydrologic Cycle Components

Evaporation, transpiration, runoff, condensation, precipitation, infiltration.

25
New cards

Watershed

Land draining into a body of water.

26
New cards

Aquifer

Porous underground rock layers allowing slow water movement.

27
New cards

Cone of Depression

Water table lowering around a pumping well.

28
New cards

Salt Water Intrusion

Saltwater intrusion into aquifers due to overpumping.

29
New cards

ENSO

El Nino Southern Oscillation affecting air pressure over the South Pacific.

30
New cards

Reduction

Scrubbers, burn low sulfur fuels:Methods to reduce air pollution by using scrubbers and low sulfur fuels.

31
New cards

Carbon Dioxide (CO2)

A greenhouse gas produced by the combustion of fossil fuels, contributing to global warming.

32
New cards

Carbon Monoxide (CO)

Generated from incomplete combustion of fossil fuels, binds to hemoglobin reducing oxygen transport in blood.

33
New cards

Ozone (O3)

Formed as a secondary pollutant from reactions involving NO2, UV, and VOCs, causing respiratory irritation and plant damage.

34
New cards

Radon (Rn)

Naturally occurring radioactive gas from the decay of uranium, leading to lung cancer.

35
New cards

Greenhouse Gases

Includes H2O, CO2, methane, and CFCs, trapping heat causing global warming.

36
New cards

Effects of Global Warming

Result in rising sea levels, extreme weather, droughts, famines, and extinctions.

37
New cards

Greenhouse Effect

Essential for life but accelerated leads to global warming.

38
New cards

Ozone Depletion

Caused by substances like CFCs, leading to increased UV radiation and harmful effects.

39
New cards

Love Canal, NY

Site where buried chemicals caused health issues like birth defects and cancer.

40
New cards

Main Components of Municipal Solid Waste

Predominantly paper, managed mainly through landfills.

41
New cards

Sanitary Landfill Problem and Solutions

Issues like leachate and methane gas are addressed by linear collection systems and gas collection.

42
New cards

Incineration Advantages

Reduces waste volume by 90% and produces waste heat for energy generation.

43
New cards

Incineration Disadvantages

Generates toxic emissions, requiring scrubbers, and disposal of ash containing heavy metals.

44
New cards

Best Way To Solve Waste Problems

Focus on reducing waste at the source to minimize environmental impact.

45
New cards

Deserts

Cover about one fifth of the Earth’s surface, with rainfall less than 50 cm a year, occurring mostly at low latitudes and supporting specialized vegetation and animals.

46
New cards
