The map of the United States that is representing the soil erosion, shows us a trend that the soil erosion is the biggest in the areas where there is the most agricultural activity in the country, mostly the Midwest, the southern part, and the lowlands east of the Appalachians.
It is no wonder that the areas where there is the highest agricultural activity have the highest wind and water erosion. What is now agricultural land, in the past had a natural protection of wild plants, but now it doesn't.
The constant plowing of the soil results in making the soil much more loose several times in a year, sot he wind is able to pick up particles easily, and the water is able to easily move the top layers.
The heavy usage of pesticides, herbicides, fungicides, and artificial fertilizers are also making the soil very loos, so the erosion has big effect.
Depending on the irrigation method, it can have a big effect, especially if it is irrigation through ditches, as the water will be pushing from one side and moving toward the other side, moving the top soil with it.
1) <span>No, because shearing causes strike-slip faults or normal faults are caused by tension.
2) </span><span>Diagram A shows a section of rock that contains three different layers. All layers are parallel and are equal in thickness. There are no forces being exerted on the rock layers.
3) </span>Compression: stresses are directed inward - produces thrust faults, reverse faults, or folding; Tension: stresses directed outward
Answer:
I think b)
Explanation:
Great Zimbabwe, extensive stone ruins of an African Iron Age city. It lies in southeastern Zimbabwe, about 19 miles (30 km) southeast of Masvingo (formerly Fort Victoria).
The answer is faults because when divergent boundaries occur, the tectonic plates move away from each other, therefor creating a fault in the earths crust.
<span>How are the trees different in these three biomes?
•Tropical forest consists of more…Tropical plants of course! These being: Palms, Orchids, ferns, vines, mosses, and more.
•Temperate forest tend to stick with more “dry” plants per say. Some examples: Oak, hickory, maple, elm, willow, ect.
•Ending with Boreal Forest, (otherwise known as taiga) inhabit plants of
which can survive harsher, colder climates. This includes: Pine, fir,
and spruce. “Needle like pines” if you will.
Describe the three soil types. Before you learned about the biomes,
which of the three would you have thought would have had the richest
soil? Why?
•Tropical Forest: Soil is nutrient-poor and acidic. Decomposition is rapid and soils are subject to heavy leaching.
•Temperate Forest: Soil is fertile, enriched with decaying litter.
•Boreal Forest: Soil is thin, nutrient-poor, and acidic.
Out of the three biomes, *Insert thoughts here*
For each of the three biomes, describe what you see as the biggest
challenge to plants and animals. What environmental factor most drives
their adaptations? (Example: For the desert, the factor would be the
lack of water and heat.)
•Tropical Rain forest: The lack of nutrients in the soil.
•Temperate Forest: Acid rain. <It kills trees & plants.
•Boreal Forest: Poor soil. </span>
