The smear is stained with a special dye, which helps tell the difference between various types of white blood cells. Five types of white blood cells, also called leukocytes, normally appear in the blood: 1  Neutrophils.  Lymphocytes (B cells and T cells)
What type of plate boundary leads to subduction? Convergent plate boundaries lead to subduction. Subduction occurs  when one tectonic plate rides over the edge of another tectonic  plate which sinks into the mantle as theyâ¦ converge.
The common points where the plates touch one another is where the earthquake starts or the focus. As seen in the picture above, subduction zones are on the borders of each tectonic plate. As they crash together one plate moves below the other which causes subduction zone earthquakes. Earthquakes are one of the biggest natural disasters known to man. Earthquakes occur when there is a sudden release of energy below the earths crust at the focus.
