The document provides an overview of the physical environment and its main components: 1) Landforms and rocks are created and changed by geological processes occurring beneath and on the Earth's surface, such as mountains, volcanoes, limestone, and granite. 2) Rivers, lakes, and oceans make up the water component, with rivers flowing from high to low ground and possibly including waterfalls and deltas. 3) Weather and climate describe the gaseous atmosphere, with weather being short-term atmospheric conditions and climate describing longer-term weather patterns over 30 years or more that include elements such as temperature and rainfall. 4) Natural vegetation consists of plants that have grown without being planted by people.

•
created and changed by processes beneath and on the earth’s
surface
• Examples : mountains and volcanoes , Limestone and granite
Grand Canyon in USA

cave

4. Rivers, lakes & oceans
• Rivers are stream of water which flow from high ground to low ground
• It may include waterfalls and deltas

5. Weather and climate
• Earth is covered with gaseous environment called the atmosphere.
• Weather. Condition of the atmosphere over a period of time.
• Climate is a weather pattern over 30 years and more.
• Elements of weather & climate
• Temperature
• Rainfall
• wind

6. Natural Vegetation
• Plants which have not been planted by people but have grown
naturally.

7. Interrelationships between the components
• The amount of rain affects the natural vegetation.
• Rivers create and change the landforms on the Earth’s surface

8. Activity 1
• This photograph of a
rainstorm over Yukon
River, Canada, demonstrates
how the components of the
physical environment such as
weather, river and landforms
are interrelated.
• Can you describe their
interrelationships?

9. Activity 2
• The physical environment
comprises the living
environment, water, air and
land, which are all closely
related to one another.
• Discuss the interrelationships
between the various
components from this
photograph.
