I believe the answers should be A. And C
The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.
<h3>
How do materials move within the earth?</h3>
The Earth's thermal energy is the main cause of the movement of materials within the earth surface. The Large continent-size plates moves slowly about the Earth's surface, which is driven by the thermal energy. The Convection currents transfer hot, buoyant magma to the lithosphere's layer at plate boundaries and hot spots. Convection currents also transfer denser, cooler material from the crust to Earth's interior through the process of subduction.
So we can conclude that: The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

Answer:
The muscle fibers are pulled by the myosin and sarcomere together, resulting in the shortening of the fibres, but the sarcomere and myosin just move.
Explanation:
During muscle contraction, each sarcomere shortens, bringing the Z discs close together. There is no change in the width of the A band but both I bands and the H zone almost completely disappear. These changes are explained by actin and myosin filaments sliding past one another, so that the actin filaments move into A band and H zone. Muscle contraction thus results from an interaction between the actin and the mosin filaments that generates their movement relative to one another. The molecular basis for this interaction is the binding of the myosin to actin filaments that generate their movement relative to one another.
