- Q9The center of the Earth is as hot as the surface of the sun. The inner core is a sphere of hot, solid metal. Surrounding the inner core is the liquid outer core. The inner core is so hot, it melts the metal in the outer core. If the inner core is extremely hot, then why is it not a liquid?Pressure in the outer core is intense enough to melt the metals.The heat from the inner core melts the metals of the inner core.Pressure in the inner core is intense enough to keep it a solid.The inner core is much hotter than the inner core.30sEditDelete
- Q10A student wondered if the temperature of the outer core was higher than the temperature of the inner core. What would make the student think the outer core would be hotter?It is solid.It is a gas.It is liquid.It has plasticity.30sEditDelete
- Q11Suppose a planet very similar to Earth exploded, and pieces of its core were discovered in space. What would be a reasonable prediction of the element contained in these core pieces?CarbonHydrogenSilicaIron30sEditDelete
- Q12What is/are the most abundant element(s) in the Earth’s crust?Hydrogen and nitrogenNitrogenIron and nickelOxygen and Silicon30sEditDelete
- Q13A scientist is looking for a rocky planet with a chemical composition similar to that of Earth. What are two elements the scientist should look for in the composition of the planet?Nitrogen and oxygenSilicon and ironCopper and zincHydrogen and oxygen30sEditDelete
- Q14A student noted that oil floats on water because it is less dense than water. Relate your ideas about density to what you know about Earth’s layers. What inference can you make about silicates and iron?Silicate is less dense than iron.Silicate and iron are less dense than cold water.Silicate and iron have the same density.Iron is less dense than silicate.30sEditDelete
- Q15A student is making a symbolic model of the Earth’s layers and is using a thick layer of peanut butter with a broken graham cracker on top to represent the asthenosphere and the lithosphere. Why did the student choose a broken cracker?The crust is solid and brittle.The lithosphere has plasticity.Peanut butter goes well with graham crackers.The lithosphere is brown.30sEditDelete
- Q16Select the model the best represents the Earth’s layers.CDBA30sEditDelete
- Q17Why is the crust able to float and move on top of the mantle?Because the mantle is a solid with plasticityBecause the mantle is a hot plasmaBecause the mantle is liquidBecause the mantle is a gas30sEditDelete
- Q18A student was looking at a model of the structural layers of Earth and noted that the layers alternate between a plastic or semi-liquid state and a more solid state. The student wondered why the solid layers did not sink into the liquid layers. What is the best response to the student’s question?The inner layers are hotter than the outer layers.The outer layers are less dense than the inner layers.The inner layers are less dense than the outer layers.The outer layers are hotter than the inner layers.30sEditDelete
