Earth formed in layers because the various materials that made up early Earth were different temperatures. How might the formation of Earth have been different if all of the materials were the same temperature? If the temperature of early Earth had been uniform, or the same throughout, the Earth may not have formed in layers. If the temperature of early Earth had been uniform, or the same throughout, the Earth would have formed more layers. If the temperature of early Earth had been uniform, or the same throughout, the Earth would have been a gas giant. The temperature is irrelevant. Only gravity caused Earth to form in layers, and it would have made no difference if the temperature of early Earth were uniform throughout.

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
