How important are water and carbon to life on Earth?
Water and carbon are essential in supporting life on Earth. They both move between land, oceans and the atmosphere. Find out why water and carbon are so important. Read More about “How important are water and carbon to life on Earth?”…
Introduction to water and carbon cycles
Water and carbon are cycled through open and closed systems. Systems are made up of inputs, stores and processes and outputs. These components are linked together by flows of energy and materials through the system. Read More about “Introduction to water and carbon cycles”…
Water Cycle
The water cycle is a system with inputs, processes, stores and outputs. The water cycle has distinctive processes and pathways. 97% of all water on Earth is stored in Oceans. The remaining 3% is fresh water. Read More about “Water Cycle”…
Rivers >
River Processes: erosion, transportation and deposition & Hjulström Curve
There are three main types of processes that occur in a river. These are erosion, transportation and deposition. Read More about “River Processes: erosion, transportation and deposition & Hjulström Curve”…
Drainage Basin Hydrological System
Drainage basin hydrological systems are local open systems. A drainage basin is an area of land drained by a river and its tributaries (river system). Read More about “Drainage Basin Hydrological System”…
Water Balance
The balance between inputs and outputs is known as the water balance or budget. The water balance can be shown using the formula: Read More about “Water Balance”…
Coasts >
Coastal Landforms of Deposition
Coastal landforms of coastal deposition occur where the accumulation of sand and shingle is greater than it is removed. Read More about “Coastal Landforms of Deposition”…
Coastal Protection and Management – Hard Engineering
Hard engineering techniques are typically used to protect coastal settlements. They are used to deflect the power of waves. Read More about “Coastal Protection and Management – Hard Engineering”…
Longshore Drift
Longshore drift is a process responsible for moving significant amounts of sediment along the coast. This usually occurs in one direction as dictated by the prevailing wind. Read More about “Longshore Drift”…
