  Troposphere
  
  the lowest layer where weather occur and contain most of our breathable air
• 
  Stratosphere
  
  contain the ozone layer that protect us from harmful ultraviolet radiation
• 
  Mesosphere
  
  where most meteors burn up upon enter earth’s atmosphere
• 
  Thermosphere
  
  contain the ionosphere, which reflect radio waves
• 
  Exosphere
  
  the outermost layer that gradually transition into space

The atmosphere consist principally of nitrogen (78 % ) oxygen ( ( % ),)nd trace gases include argon, carbon dioxide, and water vapor. These gases regulate temperature, filter radiation, and provide the oxygen necessary for respiration.

Climate and weather

Climate represent the long term patterns of temperature, humidity, atmospheric pressure, wind, precipitation, and other meteorological elements in a give region. Weather, meantime, refer to the short term atmospheric conditions experience at a particular time and place.

Key factors affect climate include:

• Latitude and altitude
• Proximity to large bodies of water
• Ocean currents
• Prevail winds
• Mountain range

These atmospheric components instantly influence human activities, from agriculture to urban planning, and play a crucial role in determine which species can thrive in specific regions.

Water bodies

Water cover roughly 71 % of earth’s surface and exist in various forms:

• 
  Oceans
  
  vast saltwater bodies that cover approximately 96.5 % of all earth’s water
• 
  Lakes
  
  inland bodies of stand water that vary in size and depth
• 
  Rivers and streams
  
  flow freshwater systems that transport water from higher to lower elevations
• 
  Groundwater
  
  water store beneath the earth’s surface in soil pore spaces and fractures in rock formations
• 
  Glaciers and ice caps
  
  frozen freshwater reserves that cover approximately 10 % of earth’s land area

These water bodies regulate temperature, provide habitats for countless species, and supply essential water for drinking, agriculture, and industry.

The water cycle

The water cycle (or hydrologic cycle )describe the continuous movement of water on, supra, and below earth’s surface through processes include:

• Evaporation and transpiration
• Condensation
• Precipitation
• Runoff and infiltration

This cycle purifies water, transport minerals, and help regulate earth’s temperature by redistribute heat energy.

Lithospheric components

Land and soil

The lithosphere comprise the solid outer layer of earth, include the crust and upper mantle. Land formations vary wide across the globe, create diverse landscapes:

• 
  Mountains
  
  elevated landforms that rise conspicuously above surround areas
• 
  Plains
  
  flat or mildly roll areas with minimal elevation changes
• 
  Plateaus
  
  elevated flat lands that rise acutely above surround areas
• 
  Valleys
  
  low lie areas between hills or mountains
• 
  Deserts
  
  arid regions with minimal precipitation

Soil, the thin layer cover much of earth’s land surface, consist of mineral particles, organic matter, water, and air. Different soil types support various ecosystems and agricultural activities.

Geological features

The earth’s crust contain various geological features form through tectonic activity and erosion:

• 
  Tectonic plates
  
  large sections of the earth’s crust that move relative to one another
• 
  Fault lines
  
  fractures in the earth’s crust where tectonic movement occur
• 
  Volcanoes
  
  openings in the earth’s crust through which molten rock, ash, and gases erupt
• 
  Caves and caverns
  
  natural underground chambers form through various geological processes

These geological components continue to shape our planet through processes like plate tectonics, weathering, and erosion.

Natural resources

Mineral resources

The earth contain numerous mineral resources that form over millions of years:

• 
  Metals
  
  iron, copper, aluminum, gold, and other metallic elements
• 
  Non-metallic minerals
  
  salt, gypsum, clay, and phosphates
• 
  Build materials
  
  stone, gravel, and sand
• 
  Precious stones
  
  diamonds, emeralds, and other gemstones

These resources provide raw materials for construction, manufacturing, technology, and energy production.

Energy resources

The physical environment contain various energy sources:

• 
  Fossil fuels
  
  coal, oil, and natural gas form from ancient organic matter
• 
  Renewable energy sources
  
  solar radiation, wind, flow water, and geothermal heat
• 
  Nuclear resources
  
  uranium and other radioactive elements

These energy resources power our modern civilization, though their extraction and use oftentimes impact other environmental components.

Biotic interactions with the physical environment

Ecosystems

While ecosystems include both live (biotic )and nonon-living (iotic ) )mponents, the physical environment provprovides foundation for ecosystem development. Different physical environments support distinct ecosystems:

• 
  Forests
  
  dominate by trees and woody vegetation
• 
  Grasslands
  
  areas where grasses predominate
• 
  Wetlands
  
  land areas saturate with water
• 
  Marine ecosystem
  
  oceans, seas, and estuaries
• 
  Deserts
  
  arid regions with specialized plant and animal adaptations

The physical characteristics of these environments — include temperature, precipitation, soil type, and topography — determine which species can survive and thrive.

Environmental cycles

Several important cycles connect the physical environment with live organisms:

• 
  Carbon cycle
  
  the movement of carbon between the atmosphere, oceans, soil, and living organisms
