The soil texture is determined by the relative proportions of the individual particles of sand, silt, and clay that make up the soil. A soil texture triangle plot is a visual representation of the proportions of sand, silt, and clay in a soil sample.
Volcanic cone – Landform of ejecta from a volcanic vent piled up in a conical shape; Volcanic crater – Roughly circular depression in the ground caused by volcanic activity; Volcanic dam – Natural dam produced directly or indirectly by volcanism; Volcanic field – Area of Earth's crust prone to localized volcanic activity
Land is often defined as the solid, dry surface of Earth. [1] The word land may also collectively refer the collective natural resources of Earth, [2] including its land cover, rivers, shallow lakes, its biosphere, the lowest layer of the atmosphere (troposphere), groundwater reserves, and the physical results of human activity on land, such as architecture and agriculture.

This term is generally used to refer to a small local area of ground water that occurs at an elevation higher than a regionally extensive aquifer. The difference between perched and unconfined aquifers is their size (perched is smaller). Confined aquifers are aquifers that are overlain by a confining layer, often made up of clay.
It is rich in nutrients and retains moisture in the soil. Humus is the Latin word for "earth" or "ground". [2] In agriculture, "humus" sometimes also is used to describe mature or natural compost extracted from a woodland or other spontaneous source for use as a soil conditioner. [3]
A bog usually is found at a freshwater soft spongy ground that is made up of decayed plant matter which is known as peat. They are generally found in cooler northern climates and are formed in poorly draining lake basins. [6] In contrast to fens, they derive most of their water from precipitation rather than mineral-rich ground or surface water ...
It was perfect for the “Barbie” movie, Eilish and Finneas have both said, because it represents how Barbie floats gracefully down from her pink house in an early scene, then later falls to the ...
Gravel (largest fragment in this photo is about 40 mm (1.6 in)) Gravel (/ ˈ ɡ r æ v əl /) is a loose aggregation of rock fragments.Gravel occurs naturally on Earth as a result of sedimentary and erosive geological processes; it is also produced in large quantities commercially as crushed stone.
