Geo - Earth

Morpho - Structure

Logy - Study

Geomorphology is the study of earth's origin, landforms and the processes that shapers them.

Father of geomorphology - William Marris

(1). Youthful stage

(2). Mature stage

(3). Old Age stage

(4). Renewal stage

🔸 Asymmetrical

🔸 Overturned

🔸 Recumbent

🔸Isoclinal

Sudden movement are occurs at the tectonic plate margins.

Example ÷Earthquakes

Volcanic eruption

Depressions formed

when wind removes

loose surface material.

Depositional Landforms

Mounds or ridges of sand deposited by wind.

The beginning of a river or stream, often found in highland or mountainous areas.

2. Watershed Boundary

The boundary separating one drainage basin from another.

3. Confluence

The point where two or more rivers or streams meet.

2. When two streams of the same order merge, the resulting stream increases by

1 + 1 = 2

2 + 2 = 3

1. Steep Gradient – The river flows down from a high elevation, giving it a lot of energy.

2. V-Shaped Valleys – Vertical erosion by the river cuts deep into the land, forming narrow, steep-sided valleys.

3. Waterfalls & Rapids – Occur where there are layers of hard and soft rock; soft rock erodes faster, creating drops.

4. Erosion Dominates – Mainly vertical erosion (downward cutting), using processes like hydraulic action and abrasion.

2). Gorge and Canyon.

3). Waterfalls.

4).Meanders.

5). Oxbow Lakes.

6). Alluvial Fans and Deltas.

Homes, vehicles and personal belongings can be destroyed.

Rainwater absorbs carbon dioxide from the atmosphere and soil faming a weak carbonic acid.

Coast - strip of land that combines the mainland and the sea.

Alpine glaciers, also known as mountain glaciers.

Ice Sheets

Ice Sheets are found in polar regions near the Earth's poles.
