Shelterbelts can offer a durable, reasonably priced solution for minimizing wind erosion on farms. Shelterbelts are used to lessen wind speed in the protected area and lessen soil erosion on agricultural land.
A windbreak is a planting that typically consists of one or more rows of trees or shrubs that are placed so as to offer protection from the wind and prevent soil erosion. On farms, they are frequently planted as hedgerows along the boundaries of fields. Trees are arranged in rows along fence lines in shelter belts. They are mostly grown to provide shade in hot times and shield livestock or crops from cold winds. Shelter belts also lessen wind erosion in areas with a lot of cultivated land, like Canterbury. This is called Shelter belts. Sand and loam become more cohesive when the soil is damp, which temporarily prevents wind erosion. Two strategies are used to control wind erosion: lowering ground-level wind speeds and boosting soil cohesiveness, which increases a soil's wind resistance.

which of the following is true populations are made up of communities communities are made up of populations communities are made up of ecosystems populations are made up of ecosystems
communities are made up of populations.
Populations make up species. It relies on the species' distribution and the size (or lack thereof) of the geographical area. Some species only occur in relatively small areas, such as on a single island or the summit of a single mountain worldwide. The entire species is represented by the one colony on the island or summit. Such populations are particularly fragile from a conservation standpoint; if something were to happen to that one population, the entire species would be gone, and it would become extinct. Communities are made up of all the populations of various species in a specific location.
The community concept's focus on several populations of all the various species in the area and how these species interact with one another is its most crucial aspect. Each population is made up of individuals of a specific species, and these individuals interact with one another both within and outside of their own species (e.g., fighting, grooming, mating, and pollination) (e.g., hunting them for food, using them as a place to build a nest, growing on them).

Cold fronts represent areas where a package of cold air is advancing to replace a package of warm air. What type of weather would you expect to form at the boundary between these two air masses?.
Weather symptoms that arise due to the meeting of two air masses, namely rain, high precipitation, and storms. In a cold front setting, the boundary between a cold and warm air mass is relatively steep, usually causing the warm air in front of it to rise rapidly. The upward air causes cumulonimbus clouds and causes rain and lightning.
Boundary between Cold Front and Warm FrontThe meeting of cold fronts and warm fronts makes warm air rise up and causes the formation of stratus clouds which are cloudy and contain masses of water. This then causes the formation of what is known as a weather front.
The strength of each front can be seen from the temperature difference between the two air masses. In simple terms, the greater the gradient or temperature difference, the stronger the front will be.
Then, a stronger front leads to a greater potential for rain and storms. On the other hand, a weak front will only be able to produce a few clouds, decrease humidity, or wind.

A strike-slip fault, also known as a transform fault, differs from a reversal fault in that it can travel left or right. A thrust fault or reversal fault travels upward and downward.
The block above the fault goes up in relation to the block below the fault when there is a reverse fault.
The most typical fault kind is referred to as a normal fault. It develops when rock above an inclined fracture plane slides over the rock on the opposite side of the fracture as it descends.
A strike-slip fault is a vertical (or nearly vertical) fracture in which the majority of the movement of the blocks has been horizontal.
Normal faults are caused when two plates that are stacked one on top of the other slip past one another. One plate sliding under the other results in a vertical offset, which causes reverse faults. When two plates pass each other horizontally, strike-slip faults occur.

What is the evidence from fossils that supports plate tectonics?.
Some of the early hints that scientists used to recreate historical plate movement were the discovery of identical or similar fossils in regions that were separated by great distances.
Give a brief account on plate tectonics.In the 1960s, plate tectonics as a theory was developed. The lithosphere, which is Earth's outermost stiff layer and is normally around 100 km (60 miles) thick, is believed to sit on top of the asthenosphere, which is Earth's plastic (moldable, partially molten) layer. Seven extremely large continental and oceanic plates, six or seven medium-sized regional plates, plus a number of smaller plates make up the lithosphere. These plates interact at their boundaries where they converge, diverge, or slip past one another at speeds of 5 to 10 cm (2 to 4 inches) per year or less.
Although earthquakes and volcanoes can occur in plate interiors, it is thought that these interactions are primarily to blame for the majority of Earth's seismic and volcanic activity. Mountain formation results from plate motions, which also cause continents to break apart and oceans to form where plates pull apart or diverge. The continents are enmeshed in the plates and passively drift with them, causing the Earth's geography to change significantly over millions of years.

The plate tectonic conditions that result in mafic magmas include mid-ocean ridges, continental rifts, oceanic and continental volcanic arcs.
Oceanic mid-ridges The two plates separate near the mid-ocean ridges, when the magma effusion creates the new oceanic crust. The two plates move apart, revealing the interior of the earth.
Continental rift The effusion of the magma creates a new oceanic crust, and the two plates separate. As a result, the melt in the continental drift forms. The crustal thickness therefore thins.
