A current is a movement of water. Currents can occur in oceans, seas, and rivers. In coastal waters, tides cause the greatest daily changes in water currents. Coastal currents are intricately tied to winds, waves, and land formations. Winds that blow along the shoreline—longshore winds—affect ...

Pools, Sinkholes, Lapies and Limestone Pavements Pool, also known as a sink, a sinking, a plunge or a bottomless pit. A pool is a depression in the ground caused by a natural process called dissolution in which water gradually erodes the surface beneath it creating a cave but never reaching all ...

Percolation is the way in which water moves through solids. Rain seeps into the ground and groundwater flows towards the streams to become surface water or seeps into the underground reservoir, or aquifer. The water then moves through pores within the rock. This process of groundwater movement ...

There are two types of sedimentary landforms: depositional and erosional. Depositional landforms result from layers of sediment being deposited by water, wind or ice. Erosional features occur when the mechanical actions of glaciers, rivers and waves have removed materials from the earth's ...

There are numerous types of landforms; we'll be starting with the erosional because they make up the majority of "land." Erosional landforms include headlands, bays, caves, arches, stacks, stumps and wave-cut platforms. There are also depositional landforms such as beaches, spits and bars. ...

Water flows over the land surface in much the same way as it flows over a carpet, following paths of least resistance. The difference is that water slowly erodes the land where the flow is concentrated. Overland flow tends to be concentrated along roads, railway banks and contours. Depending ...

Water is one of the most destructive agents in nature. It flows almost everywhere over the land surface, leaving its mark by eroding solids, dissolving minerals, and picking up debris. This running water dissolves rock, picks up soil particles, and carries them downstream as suspended load. ...

Soil development is the major way in which soil changes with time, but there are other changes that can take place over time. Erosion, forest clearing, and forest succession would be some examples of other ways in which soil could change over time. These processes would all cause a depletion in ...

There are various factors that influence the formation of soils. For example, the parent material's role as a basis for soil formation can be discussed as one of the soil forming factors as it is one of the most important factors in the ecological system. Parent material, which consists of ...

Soil forms continuously, but slowly, from the gradual breakdown of rocks through weathering. Soil can be formed in a number of different ways including chemical or physical means which often take place simultaneously. Weathering can be a physical, chemical or biological process: Physical ...
