Heat generated from the radioactive decay of elements deep in Earth's interior creates magma or superheated molten rock in the asthenosphere. Using a method of heat transfer (conduction, convection, or radiation), explain how the super hot magma is transferred up to the Earth's crust, creating the currents you see here.
A) Heat energy produced in the core radiates up through the magma. The heat energy forces the warming magma upward toward the crust. When the magma cools, it sinks back down toward the core.
B) Heat energy is conducted up through Earth's layers. The metallic minerals within the layers are excellent conductors of heat. As the heat energy travels through the rock, some melts and rise up to the crust.
C) The super-heated magma creates convection currents by a combination of radiation and convection. Heat radiates through the magma. Some magma melts because of its chemical composition and flows or convects up to the crust.
D) The deep, hot magma becomes less dense than the cooler, upper mantle rocks and it rises. At the same time, the magma close to the surface cools and sinks to replace the rising magma: this movement creates convection currents.

Quickly! brainliest if two people answer! 1. the blood has red blood cells, white blood cells and platelets. red blood cells carry oxygen to other cells in the body. cells need oxygen to live. white blood cells destroy certain germs. they protect our bodies from disease. which question is answered in this paragraph? (a) what is the role of blood vessels? (b) what type of cells are attached to bones? (c) what type of blood cell to clot your blood? (d) what are the different types of blood cells? 2. which sentence from the section "stem cells" best explains the role of stem cells? (a) when one kind of cell stops working, stem cells can . (b) they can turn into that cell and take its place. (c) scientists are studying new ways to use stem cells. (d) these cells can people heal faster. 3. read the selection from the section "nerve cells." nerve cells send messages to the rest of our bodies. these messages move between the brain, spinal cord and various organs. nerve cells are also called neurons. fill in the blank. a "neuron" is a (a) cell that moves information from the brain to other parts of the body (b) stem cell that has both an axon and a dendrite (c) cell that controls the fingers of a body (d) cell that makes up the spinal cord 4. some muscles in our body move without us telling them to. these are called involuntary muscles. some examples are the cardiac muscle cells inside the heart. these cells the heart relax and fill with blood. what is the best definition of "involuntary" based on the context clues? (a) something that happens on its own (b) trying hard to do something (c) something moving back and forth (d) easily moved
