Answer:

Heat energy from the earth's core

Explanation:

The earth is comprised of hot molten rock materials in its extreme interior. These are dense materials namely iron, nickel and some other siderophile elements are also present. They are mostly the alloys of iron and nickel. The temperature at the core is about 6000°C. This heat energy is radiated from the interior of the earth towards the outer layers, as a result of which the convection currents are generated in the mantle. This convection current is responsible for the drifting of the lithospheric plates over the less dense layer of asthenosphere.

These plates when floats over the asthenosphere shares the following type of plate boundaries, namely-

(1) Divergent plate boundary

(2) Convergent plate boundary

(3) Transform plate boundary

Wyoming was the first state to give women the right to vote, in 1869. This helped women gain a new status, especially in the Wes
AleksAgata [21]

The roles of women as pioneer were to serve as wives,mothers, and housekeepers. These pioneer women had it impossible to be able to escape. At this job they were to work with men as partners to bring food to their youngsters. Women's pioneer life was not so dangerous and hard. Living as a pioneer brought domination qualities of each individual.  As a result women learned to become independent of themselves at an early age it also taught them to face many consequences life brought. The pioneer women had the most important part on the frontier, and that is why we believe that the strongest people were in fact the pioneer women. The role of the woman was wife, mother, helpmate of her husband and the homemaker. It would stay this way for many years to come.    By the year 1869 when the first transcontinental railroad was finished, over 350,000 pioneers had taken the Oregon Trail to start a new life. Many of these were women and most were accompanied by children. Laura Ingalls Wilder was one of these women, and she even wrote a book describing her experiences as a young pioneer woman. Other women like Annie Bidwell, did more than just write books. She founded the entire Sancramento Valley society. She also helped with gaining women suffrage, or the right to vote. Wyoming was the first state to declare that women had the right to vote, and others followed suit. She was even friends with Susan B. Anthony, the woman that helped with getting women around the country the right to vote. And also, Laura Ingalls helped with the temperance movement, which was a movement to stop the drinking of alcohol.

      During the 1800's slavery began to increase in the West. The North worried that the states that allowed slavery would take over Congress if these new territories joined the Union as slave states. If the West joined the Union as free states, slave states would be outnumbered in Congress by free states, so Southerners began demanding that slavery should continue in the western states. Arguments over slavery in the new states helped bring on the Civil War which was fought from 1861 to 1865.  Slavery was abolished in the United States in 1865.
