Major landforms like mountains and plains are shaped by tectonic plates and erosion from water, wind, and glaciers over millions of years. Glaciers can scoop out basins that become lakes when the ice melts, and water erosion from rivers and streams carves out valleys and canyons as it flows downhill and joins larger rivers on its way to the ocean. Bodies of water like lakes and rivers have significantly impacted human settlement and development.
Seeks to understand how nature behaves by observing and correlating available factual information. Our understanding of science is therefore based upon, and limited by, the factual information available.
In these slides you will learn briefly about difference about weathering and erosion, different types of erosion and cycle of erosion, transport agents and landforms what are its influences on topography and types of Landforms..
Earth is the third planet from the Sun and the only object in the Universe known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4 billion years ago.[24][25][26] Earth's gravity interacts with other objects in space, especially the Sun and the Moon, Earth's only natural satellite. Earth revolves around the Sun in 365.26 days, a period known as an Earth year. During this time, Earth rotates about its axis about 366.26 times.[n 5]
Earth's axis of rotation is tilted, producing seasonal variations on the planet's surface.[27] The gravitational interaction between the Earth and Moon causes ocean tides, stabilizes the Earth's orientation on its axis, and gradually slows its rotation.[28] Earth is the densest planet in the Solar System and the largest of the four terrestrial planets.
Earth's lithosphere is divided into several rigid tectonic plates that migrate across the surface over periods of many millions of years. About 71% of Earth's surface is covered with water, mostly by oceans.[29] The remaining 29% is land consisting of continents and islands that together have many lakes, rivers and other sources of water that contribute to the hydrosphere. The majority of Earth's polar regions are covered in ice, including the Antarctic ice sheet and the sea ice of the Arctic ice pack. Earth's interior remains active with a solid iron inner core, a liquid outer core that generates the Earth's magnetic field, and a convecting mantle that drives plate tectonics.
Within the first billion years of Earth's history, life appeared in the oceans and began to affect the Earth's atmosphere and surface, leading to the proliferation of aerobic and anaerobic organisms. Some geological evidence indicates that life may have arisen as much as 4.1 billion years ago. Since then, the combination of Earth's distance from the Sun, physical properties, and geological history have allowed life to evolve and thrive.[30][31] In the history of the Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinction events. Over 99% of all species[32] that ever lived on Earth are extinct.[33][34] Estimates of the number of species on Earth today vary widely;[35][36][37] most species have not been described.[38] Over 7.4 billion humans live on Earth and depend on its biosphere and natural resources for their survival. Humans have developed diverse societies and cultures; politically, the world has about 200 sovereign states.

EXAMPLE
EROSION & DEPOSITION
EROSION
Is the process by which natural forces move weathered rock and soil from one place to another.
Sediment – material moved by erosion .
DEPOSITION
Occurs where the agents of erosion lay down sediment.
Mass Movement
Any one of several processes that move sediment downhill.
Different types of Mass Movement
Landslide
- occurs when rock and soil slide quickly down a steep slope.
Different types of Mass Movement
Mudflow
- mudflow is a rapid downhill movement of a mixture of water, rock, and soil.
Different types of Mass Movement
Slump
- a mass of rock and soil suddenly slips down a slope.
Different types of Mass Movement
Creep
- very slow downhill movement of rock and soil.
Water Erosion
Rills and Gullies
Rills
- tiny grooves in the soil.
Gully
- a large groove , or channel, in the soil that carries runoff after a rainstorm
Streams and Rivers
Stream
- a channel along which water is continually flowing down a slope.
River
- a large stream
Amount of Runoff
In an area depends on five main factors:
1st – amount of rain
2nd – vegetation
3rd – type of soil
4th – shape of the land
5th – how people use the land
Erosion by River
Through erosion, a river creates a waterfalls, flood plains, meanders, and oxbow lakes.
Waterfall
May occur where a river meets an area of rock that is very hard and erodes slowly.
Flood plain
Flat, wide area of land along a river.
Meander
A loop like bend in the course of the river
Oxbow lake
A meander that has been cut off from the river.
Deposits by River
Deposition creates landforms such as alluvial fans and deltas. It can also add soil to a river’s flood plain.
Alluvial Fans
A wide, sloping deposit of sediment formed where a stream leaves a mountain range.
Deltas
Sediment deposited where a river flows into an ocean or lake.
Groundwater Erosion
Groundwater can cause erosion through a process of chemical weathering.
Stalactite – hangs down from the roof of a cave.
Stalagmite – pointed piece of rock that sticks u p from the floor.
How Water Erode and Carries Sediment
Most sediment washes or falls into the river as a result of mass movement and runoff. Other sediment erodes from the bottom or sides of the river.
Abrasion- is the wearing away of rock by grinding action.
- occurs when particles of sediment in flowing water bumped into the steam again and again.
Erosion and Sediment Load
A river’s slope, volume of flow, and the shape of its trembled all affect how fast the river flows and how much sediment it can erode.
Slope
Is the amount the river drops toward sea level over a give distance.
Volume of Flow
A river’s flow is the volume of water that moves past a point on the river on a given time.
Streambed Shape
Affects the
Lakes and ponds are bodies of relatively still, or standing, water.
Although no definite size distinguishes a lake from a pond, lakes generally are larger and deeper than ponds.
Water enters lakes from streams and rivers, by rain or snow falling on or near the depression, and from groundwater.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
