This document discusses processes that shape Earth's surface, focusing on weathering and soil erosion. It notes that soil erosion can be increased by human activities like illegal logging, overgrazing, and quarrying. The effects of soil erosion include negative impacts on landforms, plants, animals, and humans. Landforms may be degraded and plants unable to grow without sufficient nutrients and water retention in topsoil. Animals and humans face issues like reduced food sources and supply of potable water, which can impact health.

10. EFFECTS ON LANDFORMS
• Appearance and structure take hundred of years
to change.
• Sand dunes
• Soil erosion can be destructive as large mass of
soil is scratched and worn away.
• Can add up to the beauty and wonder of nature

11. EFFECTS ON PLANTS
• Topsoil= topmost layer of the soil where humus or
organic materials from dead plants and animals are
found.
• Topsoil is easily carried away so, plants will not grow well
due to lack of nutrients.
• Sediments can clogged the irrigation system- no enough
water supply for the plants.
• Soil loses the ability to hold and absorb water-soil will be
dry- not suitable for vegetation.

12. EFFECTS ON ANIMALS AND HUMANS
• Less food production= less food source
• Less food supply= affect the ecosystem
• Farmers = difficulty sustaining their lives
• Mine tailing=mineral waste or leftover after
mining=pollutes the seas and rivers
• Affects aquatic animals
• Supply of potable water
• Sickness to animals and humans

13. COMMUNICATE THE DATA COLLECTED FROM THE
INVESTIGATION ON SOIL EROSION;

14. GROUP WORK
1. Brainstorming ideas regarding the content of the
slides/ powerpoint presentation.
2. Select three representatives to talk about the
effects of soil erosion on landforms, plants,
humans and animals for the group hopping next
meeting.
(group hopping= representatives of each group will
be transferring from one group to another to share
their work.)
