Study Notes

Biosphere

  • The biosphere encompasses all living organisms on Earth. It is the region where life thrives, encompassing air, water and land.
  • The biosphere is comprised of the atmosphere, hydrosphere, and lithosphere.
  • The atmosphere is a layer of gases that surrounds the Earth, vital for breathing, photosynthesis, and protecting us from harmful UV radiation.
  • The hydrosphere includes all Earth's water, serving as a habitat for aquatic organisms.
  • The lithosphere, or the Earth's crust, provides minerals essential for life.

Biomes

  • Biomes are large regions with distinct climates that support specific plant and animal communities.
  • Biomes can be divided into aquatic (water) and terrestrial (land) biomes.
  • Aquatic biomes can be further classified as marine (saltwater) or freshwater.

Marine Biomes of South Africa

  • South Africa has a diverse coastline influenced by warm and cold currents.
  • The eastern coast is warmed by the Agulhas Current.
  • The western coast receives the cold Benguela Current, rich in nutrients.
  • The south-western and southern coast experience a mixing of these water masses.
  • The ocean's tides, currents, temperature changes, oxygen, and salt content influence the marine life found along the coastline.

Sandy Beaches

  • Sandy beaches are characterized by shifting sand, dunes, continuous wave and current action, and an intertidal zone where ocean meets land.
  • The intertidal zone experiences cyclical wet and dry periods.
  • This environment requires highly adapted organisms to survive.
