Answer:
The correct answer is C. An unintentional consequence of the arrival of horses to America brought by Spanish conquistadors was that by the mid-1700s, the Plains Indians were expert horsemen who relied on their herds for buffalo hunting and trade.
Explanation:
The horse was introduced to the American continent with the arrival of the European conquerors in 1492. The European military used these animals as a means of transport, a work tool and even for military purposes.
Once introduced to the continent, this animal gave Europeans a considerable advantage in battle, as it provided faster mobility and a higher position from which to fight; its use was one of the strategic keys of the victory of the conquerors over the natives.
This animal, once introduced in the continent, began to reproduce and form increasingly numerous groups. Both Europeans and natives used it; In the case of the latter, who lived a life more in contact with nature, hunted and worked the land, the horse became an indispensable tool for day to day activities. Thus, as an indirect consequence of its introduction by Europeans, the horse became a fundamental element of the lives of Native Americans.

Answer:
Energy is very important in our life. Matter has the capacity to do work under certain conditions even though it may not be accomplished at a particular moment. A moving of water or water stored behind a dam, for example, can be made of work in a variety of at a particular.Gas or air compressed in a tank can also do work when it is released at a particular time. The capacity of matter to do work is generally called energy.
IMPORTANCE OF ENERGY:
All life on earth depends in some way upon energy. Most of the earth energy comes from the sun. It travels to the earth in rays or waves. Energy in this form is used by plants to make food. Plant food is needed to sustain life by providing nourishment for our bodies and muscles. The sun’s energy is also stored in coal, wood and oil which is also used to produce food and modify matter. It has been estimate that the amount of energy falling on the earth surface annually is equal to the energy of 250 million tons of coal.
Answer:
Three identifying properties that would help tell a geologist which depositional environment a sandstone was formed in is sorting, roundness, and composition. Sandstone that has formed in an Aeolian environment will have well sorted particles that are rounded. Sandstone that has formed in a beach/shoreline environment will also be very well sorted. Sandstone formed in rivers on land will be poorly sorted. The longer amount of time particles are transported the better sorted they will form. Rounded grains are more likely to have been transported by water or wind for a longer time such as in a sedimentary rock formed in an Aeolian environment by wind or one formed in a beach/shoreline environment by waves. Sandstone formed in an Aeolian environment will have a larger quantity of quartz as it is a more durable mineral than feldspar and ferromagnesian. Sandstone that has a significant amount of feldspar and ferromagnesium minerals is more likely to have gone through little chemical weathering and transport and was probably deposited close to the source area of the rock particles. We can also tell a lot by the kind of fossils that are fossilized in a sedimentary rock by analyzing what kind of organism or plant it is and if they were found on land or in water during that time period.
