This document discusses geomorphology and weathering. It defines geomorphology as the study of Earth's surface processes and landforms. Geomorphologists use various methods like remote sensing and field observations to understand these processes and predict future landscape changes. The document then defines weathering as the natural breakdown of rocks and minerals by physical and chemical processes. Physical weathering breaks down rocks through forces like wind and water, while chemical weathering involves processes like oxidation and acid rain. There are different types of physical weathering like abrasion, frost wedging, and thermal expansion that wear rocks down over time.

3. INTRODUCTION
Geomorphology is the study of the processes that shape the surface of
the Earth. It is a branch of physical geography that deals with the origin
and evolution of the landforms on the Earth's surface, and how they are
influenced by natural processes such as weathering, erosion, and
tectonic activity. Geomorphologists use a variety of methods to study
these processes, including remote sensing, field observations, and
modeling. They can also use this information to predict future changes in
the landscape. Geomorphology is a fascinating and dynamic field that
can help us to understand the Earth's ever-changing landscape.

4. WHAT IS WEATHERING
Weathering is a natural process that breaks down rocks and
minerals on the Earth's surface. There are two main types of
weathering: physical and chemical. Physical weathering is the
breakdown of rocks and minerals through physical processes such
as wind, water, and temperature changes. Chemical weathering,
on the other hand, is the breakdown of rocks and minerals through
chemical processes such as oxidation and acid rain. Both types of
weathering work together to break down rocks and minerals and
transport them away from their original location. Eventually, this
process results in the formation of new rocks and minerals.

5. TYPES OF WEATHERING
There are several types of weathering, which can be
categorized into two main groups: physical and
chemical. Physical weathering includes processes such
as:- Abrasion: The wearing away of rocks by wind,
water, and sand.- Frost wedging: Water gets into cracks
in rocks, freezes, and expands, causing the rocks to
break apart.- Thermal expansion: Rocks expand and
contract with changes in temperature, causing them to
break down over time.
