The Bessemer steel process affected westward expansion in the United States by enabling—
railroads to be built in order to carry people and goods to the West
Conestoga wagons to be built in order to carry people and goods to the West
interstate canal systems to be built in order to transport agricultural goods from west to east
clipper ships to be built in order to transport passengers from the East Coast to the West Coast
Answer: interstate canal systems to be built in order to transport agricultural goods from west to east
Explanation: Railroads were not an efficient form of transporting goods in 1860. Shipments through canals and rivers could reach more people in the western
The core of Earth is made out of iron and nickel. The outer core's temperature is so hot that it melts the metal. The inner core is solid metal. What causes these differences?
A. The outer core is is 2,2,300 300 km thick.
B. The inner core is kept solid by the intense pressure of all of the layers above it.
C. The inner core has a cooler temperature, allowing the metal to remain solid.
D. The inner core is made of a different metal.
Answer:
c
Explanation:
The inner core is solid because it is made of very dense, or heavy, materials - like iron and nickel. Even though it is very hot, these materials don't "melt" very easily, so they stay solid.
The inner core is kept solid by the intense pressure of all of the layers above it, which is why the inner core is solid metal. Therefore option B is correct.
What is Core?It is located at the deepest point of the Earth's interior. The inner core and the outer core are two different sorts. The inner core is solid, whereas the outside core is a liquid layer. 15% of the earth's volume, or 3500km in diameter, is made up of the core.
Our main estimate of the deep earth's temperature comes from the way iron melts at extremely high pressures. We are aware that the majority of the earth's core, which extends from 2,886 kilometers to 6,371 kilometers (1,794 to 3,960 miles), is composed of iron with some pollutants.
The transition between the liquid outer core and the solid inner core, which are both parts of the earth's core, is located at a depth of 5,156 kilometers (3,204 miles). Therefore, this lab temperature should reasonably nearly resemble the actual temperature at this liquid-solid border if we can determine the melting temperature of iron at the tremendous pressure at the boundary between the inner and outer cores.
