True. In the mantle, hotter, less dense material rises toward the Earth's surface, while cooler, denser material sinks. This process is part of mantle convection, which drives plate tectonics and influences geological activity. The continuous movement helps distribute heat from the Earth's interior to its surface.
What else can I help you with?
True or false any material that exerts magnetic force is considered a magnet?
It is true that materials that exert magnetic forces are considered magnets. This is the case since it shows they have magnetic field lines that may have been induced or were naturally present in the materials.
Magma is thought to come from the upper mantle or inner core of the earth.?
false
Is it True or false General requirements do not apply to slings used in conjunction with other material handling equipment for the movement of materials by hoist?
False. General requirements do apply to slings used with other material handling equipment for the movement of materials by hoist. These requirements ensure safety and proper usage, regardless of the equipment involved. It is important to follow established guidelines to prevent accidents and ensure safe lifting practices.
Hotspot volcanoes occur along subduction zones?
False. Hotspot volcanoes form above mantle plumes, which are localized upwellings of hot mantle material. Subduction zone volcanoes form due to the subduction of one tectonic plate beneath another, resulting in magma generation due to the melting of the subducted plate.
The inner core contains genetic material true or false?
False. The inner core of the Earth is composed of solid iron and nickel, while genetic material is found in the nucleus of cells.
The deep mantle is composed of material with a lighter density than the outer mantle?
The deep mantle is actually composed of denser materials compared to the outer mantle. These denser materials are mainly made up of silicate minerals rich in iron and magnesium, which contribute to the overall density of the deep mantle. This density variation plays a key role in the movement of material within the Earth's mantle through processes like convection.
Is this true or false formed in the mantle molten material called lava cools to form minerals below earth's surface?
This is false. Molten material below earth's surface is known as magma. It is only known as lava once it has been erupted onto the surface.
Is this truth or false the heat source for the convection currnets in the mantle is the sun?
False.
When two or more materials are combined together to form a composite material they become identifiable macroscopically true or false?
true
True or false The lithosphere includes all of the core and part of the mantle?
False. The lithosphere is the rigid outer part of the Earth, consisting of the crust and upper mantle. The core is separate and located beneath the mantle.
It is best to isolate the material quantity variance when the materials are purchased?
false- it is best to isolate them once you know how much of the material has been used. If you don't know how much is used, you can't get a variance to evaluate efficiency of how materials were used.
Much of the upper mantle thought to be made of granite true or false?
False. The upper mantle is believed to be composed primarily of peridotite.
True are false The crust is very thick and heavy?
False, the crust is actually a lot less dense than the materials below the crust, the mantle and the core, which contains the heavier elements of the earth's composition. The crust is in fact very thin in comparision to the size of the earth. The crust is only the first 40 km of under the surface, while to get to the core it is 6378km. The crust is about .62% of the earth's thickness, its almost like imagining earth as an orange and the crst being the wax covering the orange.
Does the mantel contain soil?
No the answer is false the mantle does not contain soil
Do earthquakes occur when heat travels through the mantle true or false?
False - that's a volcanic eruption.
True or false any material that exerts magnetic force is considered a magnet?
It is true that materials that exert magnetic forces are considered magnets. This is the case since it shows they have magnetic field lines that may have been induced or were naturally present in the materials.
Is A mineral is a compound of a metal mixed with other materials on rock true or false?
false. it does not have to have materials from rock :)
