Study Notes
- Earth's natural systems are diverse and unique, inspiring awe through untouched landscapes featuring distinctive landforms, vegetation, and water features.
- Cultural landscapes are inspirational to some, especially Indigenous peoples due to their strong emotional ties to the land.
- Biodiversity hotspots, covering less than 3% of Earth's land, house 44% of plant species and 35% of land vertebrate species.
People’s Connection to Nature: Worldview
- People's connection to nature depends on their worldview, influenced by attitudes, values, and expectations.
- Eco-centric worldview ascribes inherent value to all life, viewing humans as part of nature.
- Anthropocentric worldview values nature only for its usefulness to humans.
Aboriginal Peoples’ Connection to Country
- Indigenous Australians view land as a spiritual entity that owns them.
- Their identity, culture, and beliefs are deeply linked to the land and Dreamtime stories.
The Overview Effect
- Astronauts viewing Earth from space have perceived it as a shared home without borders between nations or species.
Universal Value of Earth’s Environments
- Nature possesses intrinsic value, independent of human usage.
- The global commons includes shared resources, such as oceans, vital for numerous ecosystems but owned by no single nation.
Characteristics of Earth’s Natural Systems
- Atmosphere: A mix of gases and particles, mainly nitrogen and oxygen, consisting of 5 atmospheric layers.
- Hydrosphere: The water system which includes water in liquid, vapor, and ice forms.
- Water cycles through Earth via the water cycle.
- Lithosphere: Earth's outer solid shell, composed of tectonic plates.
- Ecosphere (Biosphere): The zone where life exists, encompassing living organisms, non-living components, and energy cycles.
Factors Affecting Natural Systems
- Latitude: Impacts temperature, with the equator being warmer and the poles cooler.
- Altitude: Air temperature decreases with increasing altitude.
- Continentality: Describes the effect of ocean proximity on climate; oceanic areas experience milder temperatures.
- Oceanity: Represents the influence of oceans on both temperature and precipitation.
- Seasonality: Water bodies affect evaporation and precipitation rates.
Processes, Cycles, and Circulations Connecting Natural Systems
- Atmospheric, hydrological, geomorphic, and ecological systems are all interconnected.
Earth’s Atmospheric Layers
- Troposphere (0-10 km): The layer where weather phenomena like precipitation and wind occur.
- Stratosphere (10-50 km): Characterized by calm conditions, absence of precipitation, and the presence of the ozone layer.
- Mesosphere (50-80 km): Features strong winds, meteors, and extremely cold temperatures.
- Thermosphere (80-600 km): Notable for strong winds, auroras, and high temperatures.
- Exosphere (600 km and beyond): Features very thin air, transitioning into outer space.
Earth's Land and Water Cover
- Natural processes, cycles, and circulations, including climatic and glacial cycles, ecological succession, and vegetation invasions, have shaped Earth's land and water cover.
Summary
- Earth's natural systems and affecting cycles, such as climate and ecological shifts, have formed a diverse, interconnected environment that sustains life.
- Influencing factors are latitude, altitude, oceanity, and seasonality.
