Physical geography's primary subdisplines study the Earth's atmosphere (meteorology and climatology), animal and plant life (biogeography), physical landscape (geomorphology), soils (pedology), and waters (hydrology).

This week we'll start by looking at geomorphology - the study of landforms and the processes that create them. The understanding of these processes are an underpinning of the geography of the world today.

Take a look at this introduction to geomorphology here.

Geomorphology is concerned with the internal geologic processes of the earth's crust, such as tectonic activity and volcanism that constructs new landforms, as well as externally driven forces of wind, water, waves, and glacial ice that modify such landforms. Geomorphology developed in the 18th century with landform evolution and later the geomorphic cycle,

By the 1970s, geomorphology had grown to include the environmental problems involved in landform processes, including subsidence, landslides, and coastal processes, which all affect humans who live in certain susceptible regions. Satellite images and data help geomorphologists to describe and map landforms and observe rapid or slow changes on the earth's surface. Development of mathematical models of landform processes have influenced the direction of modern geomorphic research.

Do the following categorisations cover the entire globe? How would you catagorise your place of origin?

First order (oceans, continents; ~ 108 km2)
Second order (mountain systems, physiographic. provinces; ~ 106 km2)
Third order (mountain ranges, major valleys; ~ 104 km2)
Fourth order (volcanoes, fault blocks, valleys; ~ 102 km2)
Fifth order (cinder cones, deltas, playa lakes; ~ 100 km2)
Sixth order (sand dunes, terraces; ~ 10-2 km2)...

Homework - The general taxonomies above are used to catagories geograpical features. Choose five locations on Earth and discuss how these apply to them. (Please limit your choice to current earth based locations)

Chihaya entered and sat down, hoping he had made it to the right geography class. The lecture was interesting and he took detailed notes.

Um...yes?

Putting his pencil down, Chihaya was beginning to wonder if he should have taken this class.

Yes, this is the right class. :notes on register:

The taxonomies are by nature discrete, problems may occur at the borders between regions.

:Notes that homework was done:

{OOC- You actually did the homework. Cool.}
