wind or
water erosion?
The introduction of trees to form agroforestry systems provided sources of firewood, timber, fruits
and shade, but also helped in
erosion control, protecting
water courses through the stabilization of the soil
and as
wind breaks, regulating the velocity of the
winds.
This

erosion from
wind and water, these lunar bridges probably formed as a result of an impact in the last billion years, says Mark Robinson, a planetary geologist at Arizona State University in Tempe
and principal investigator for LRO's camera.
They protect the soil from
wind and from
water runoff, helping to control
erosion.
Erosion by
water and wind can wear down land
and create landforms like valleys
and canyons.
Erosion is the geological process in which earthen materials are worn away
and transported by natural forces such as
wind or
water.
Causes of
erosion include
wind,
water (including rainfall
and floods), the scouring action of glaciers,
and the repeated cycles of freezing
and thawing that often occur in some areas of the world.
Pasture - based cattle operations also decrease soil
erosion and improve soil fertility
and water quality by maintaining grasslands which protect soils from
water and wind erosion.

erosion by
wind and water.
Physical
and chemical weathering in hot arid environments,
and erosion, transportation
and deposition by
wind and water
Working on the same sheet, another student answered that
erosion is «the movement by
wind, running
water, glaciers, gravity
and waves.»
An hour later, we make our last stop for seeing the stunning «Castillos de Callalli», which is a sort of castle - shaped rocky formation made by
water and wind erosion.
Princen has also been known to reference scientific measuring systems, mapping,
and amateur anthropology in his work,
and his artistic practice has involved plotting ecological changes —
water currents,
wind patterns,
and soil
erosion, as well as the impacts of urban developments on the Dutch landscape.
The paintings were not literal renderings of the mountainous
and rugged terrain, but instead captured the spartan forms
and sculpted surfaces like those shaped by centuries of
erosion and movement of
wind and water as well as upheavals from tectonic shifts deep within the earth.
Each artist will address the theme utilizing locally available natural materials (salt, wood, dirt, plant - life, etc.) or natural elements
and processes (
wind, fire,
water, decay, evaporation,
erosion, etc.) in a temporary installation.
Global change, we were taught, occurred slowly
and by commonplace mechanisms: sediment carried by
water, deposited a grain at a time:
erosion effected by
water and wind, the hardest rocks slowly ground down crystal by crystal.
Erosion - The process of removal
and transport of soil
and rock by weathering, mass wasting,
and the action of streams, glaciers, waves,
winds and underground
water.
Erosion is caused by the movement of
water, which can be caused by
wind or the rise
and fall of tides.
Further, the United Nations Convention to Combat Desertification (UNCCD) defines land degradation as a reduction or loss in arid, semi-arid,
and dry sub-humid areas of the biological or economic productivity
and complexity of rain - fed cropland, irrigated cropland, or range, pasture, forest
and woodlands resulting from land uses or from a process or combination of processes, including those arising from human activities
and habitation patterns, such as: (i) soil
erosion caused by
wind and / or
water; (ii) deterioration of the physical, chemical,
and biological or economic properties of soil;
and (iii) long - term loss of natural vegetation.

The former is conducive to agriculture, the latter to
erosion — both by
water during the hurricane
and wind in the dry periods when there is no precipitation.
I can only list a few regular «goings on'that I KNOW affect sea level; I'm certain that there are others: Change in overall temperature of the oceans (a few millidegrees / mm), plate tectonics, slit from rivers,
erosion of seashores, extraction of ground
water which ultimately returns to the oceans, marine life
and its products building up the ocean floors, melting land ice, undersea discharges of a variety of «stuff» from literally hundreds of thousands of sources, often at temperatures in the 1 - 2 thousand degree range, which we are only now beginning to notice,
wind carrying dust from the land
and dropping it on the ocean.
