Introduction to Geomorphology and Biology

Hello Year 10! Today, we’re going to look at the physical environment around us. This includes the processes that shape our landforms (that’s geomorphology) and the living things that interact with these places (that’s biology). Understanding these concepts helps us see how our world works!

What is Geomorphology?

Geomorphology is the study of landforms and the processes that create them. These processes can be divided into two main types:

  1. Endogenic Processes: These happen inside the Earth.
    • Example: Earthquakes and volcanic eruptions can create mountains.
  2. Exogenic Processes: These happen on the Earth’s surface.
    • Example: Erosion by wind or water wears away rocks and soil.

Key Rules of Geomorphology:

  • Erosion: The process of wearing away rocks and soil.
  • Weathering: The breaking down of rocks into smaller pieces.
  • Deposition: When materials are dropped in a new location, like sand on a beach.

Biological Processes in Various Environments

Biological processes are all about living things and how they interact with the environment. This includes plants, animals, and humans.

Key Biological Processes:

  • Photosynthesis: Plants use sunlight to make food.
  • Decomposition: Dead plants and animals are broken down by decomposers, like fungi and bacteria, returning nutrients to the soil.
  • Habitat Creation: Different environments like forests and wetlands provide homes for various species.

Examples of Environments

  1. Coastal Environments:
    • Geomorphological Features: Cliffs, beaches, and sand dunes.
    • Biological Features: Seaweed, crabs, and seabirds.
  2. River Environments:
    • Geomorphological Features: Riverbanks, deltas, and canyons.
    • Biological Features: Fish, frogs, and river plants.
  3. Mountain Environments:
    • Geomorphological Features: Peaks, valleys, and glaciers.
    • Biological Features: Mountain goats, pine trees, and alpine flowers.

Tips and Tricks to Remember

  • Visuals: Draw maps or diagrams to see how processes shape environments.
  • Field Trips: If possible, visit local environments to observe geomorphological and biological features.
  • Flashcards: Create flashcards with terms and definitions to help you memorize key concepts.
