Most of the earth's heat is stored in earth's mantle true or false?
False
Magma is thought to come from the upper mantle or inner core of the earth.?
false
The inner core contains genetic material true or false?
its false
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.
Convection currents within the Earth cause plate tectonics due to the movement of the mantle true or false?
No. Convection currents which could lead to volcanism in the crust occur in the mantle. The crust is too cold and brittle for convection currents to occur.
The deep mantle is composed of material with a lighter density than the outer mantle?
False. Density increases with increasing depth.
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.
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.
When two or more materials are combined together to form a composite material they become identifiable macroscopically true or false?
true
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.
Is this truth or false the heat source for the convection currnets in the mantle is the sun?
False.
Most of the earth's heat is stored in earth's mantle true or false?
False
Magma is thought to come from the upper mantle or inner core of the earth?
false
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.
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 :)
True or false ohm's law describes the electrical properties of some conducting materials?
True: Resistance R = voltage V / amperage IResistance is the conducting material.
