Soil is a renewable resource because organic matter constantly replaces itself and supplies plants with needed nutrients.
Explanation:
A is correct because every time when a living organism dies, the decomposers recycle the nutrients, they end up in the soil, enrich it, thus provide nutrients for the plants.
B is not correct because the leaching is damaging the soil, not keep it in e condition.
C is not correct because the soil erosion is damaging the topsoil and stripping it from nutrients.
D is not correct because the organic matter is constantly replacing itself.
Metamorphism is the transformation in the existing rock type and means a change in the form when the rocks are subjected to changes in heat and pressure.
Regional metamorphism is also called dynamic metamorphism and foliation occurs when a rock s shortened along the axis during recrystallization. Such as mica, the foliated rocks is a product of the stress that deforms the rocks along the plane.
Dune deflation hollows are where wind has removed sand down to a level where a layer of particles too heavy for the wind to move (an armoured surface) stabilises the sand and prevents the surface being lowered further.
A crevasse is a deep, wedge-shaped opening in a moving mass of ice called a glacier. Crevasses usually form in the top 50 meters (160 feet) of a glacier, where the ice is brittle.
a mass of rocks and sediment carried down and deposited by a glacier, typically as ridges at its edges or extremity.
