Answer: The Dust Bowl was caused by several economic and agricultural factors, including federal land policies, changes in regional weather, farm economics and other cultural factors. After the Civil War, a series of federal land acts coaxed pioneers westward by incentivizing farming in the Great Plains.
Explanation:
1) Manifest Destiny: The US Government wanted settlers to move onto the Plains as they needed the land to be settled and farmed and for communities and towns to grow up and expand. This was needed if the USA was to be a rich and successful country. The government therefore promoted the idea of Manifest Destiny.

Euglena, Amoeba and paramecium are unicellular organisms. Euglena moves by flagellates, Amoeba by pseudopods and paramecium moves using cilia.
What are unicellular organisms?Unicellular organisms are lower level organisms having only one cell and an undeveloped nucleus. Most of them are aquatic lives and moves using some special organelles.
Amoeba moves by an arm-like structure emerging from its body and contains microtubules within the arms. Euglena is flagellated microorganism moving by flagella.
Paramecium is an aquatic unicellular microorganism having special whip like structure called cilia which moves it in back forth. Ciliary bodies are like oars to move in a direction.
Therefore, amoeba moves by pseudopodium, euglena moves by flagella's and paramecium moves by cilia.

Answer:
The picture
Explanation:
Explain the movement of initial energy from the sun through an energy pyramid.
Answer:
An energy pyramid is a model that shows the flow of energy from one trophic level to the next along a food chain. The pyramid base contains producers—organisms that make their own food from inorganic substances. Thus, the higher the trophic level on the pyramid, the lower the amount of available energy.
Even though it cannot be produced or destroyed, energy is emitted as heat at each level. Only 10% of energy is essentially transferred from one level to the next.
What energy from the sun through an energy pyramid?The amount of energy diminishes and the levels get smaller as you progress up the pyramid, via the trophic levels to primary, secondary, and tertiary consumers.
A figure that depicts the quantity and flow of energy transfer within an ecosystem is called an energy pyramid. The trophic levels of an ecosystem's food web serve as the basis for energy pyramids.
An energy pyramid is a diagram that depicts the movement of energy up a food chain from one trophic level to the next. Producers—organisms that create their own nourishment from inorganic materials—are found at the base of the pyramid.
Therefore, This means that the amount of available energy decreases with increasing trophic level on the pyramid.

7. If you were unsuccessful in locating the epicenter, describe how you could modify
seismograph resources to find the epicenter successfully.
Answer:
Down below
Explanation:
I would modify seismograph resources by requesting reports from earthquake stations that felt the tremors. I would then use the reports and look at the arrival time of the p waves and the s waves. If a station recorded the s waves arriving much quicker than the others, I can safely say that the epicenter was in that area. From there, I can request reports in that area and use the triangulation method to pinpoint the exact location.

Determine whether each statement describes a V-Shaped Valley or a U-Shaped Valley.
1 formed by strong streams
2 formed from the erosive
3 action of glaciers
4 deeper than they are wide
5 form in mountainous regions
6 wider and more gradual base
Answer:
U- Shaped Valley:
#3
#5
#6
V-Shaped Valley:
#1
#2
#4
Explanation:
just did the test
U-shaped valley include action of glaciers, form in mountainous region, and wider as well as more gradual base. V-shaped valley is formed by strong streams, erosive, and deeper than they are wide.
What is a valley?Valleys are low-lying areas of land that have been eroded and washed away by the combined elements of gravity, water, and ice. Some dangle, while others are feeble. They are all in the shape of a "U" or "V."
Humongous frames of snow and ice slowly creep downhill, seeking the least resistance. As the glaciers seep, they start picking up rocks and grind away at the valley floor and sides, forming a "U" and transforming the "V" into a "U." When the glacier melts, it leaves a U-shaped valley where the snow flowed.
U-shaped valleys are formed by glaciers, have a wider and more gradual base, and are found in mountainous areas. Strong, erosive streams form a V-shaped valley that is deeper than it is wide.
Thus, V-shaped valley include options 1, 2, and 4. U-shaped valley is 3, 5, and 6.
