<h3>Answer:</h3>
Convection currents in the mantle
<h3>Explanation:</h3>
Our current laws of Physics recognize that heat is transferred by one of ...
- conduction
- convection
- radiation.
Radiation is a mechanism for transferring heat through space. That mechanism doesn't really apply inside the "solid" Earth. While a certain amount of heat is transferred by conduction, the rock making up the bulk of the Earth is a poor conductor of heat.
The majority of the heat is transferred by the hot rock physically moving from the center of the earth toward the surface in the process called convection.
Answer:
Explanation:
Primary waves travel faster, move in a push-pull pattern, travel through solids, liquids and gases, and cause less damage due to their smaller size. Secondary waves travel slower, move in an up-and-down pattern, travel only through solids, and cause more damage due to their greater size.
The artery that supplies the chin and jaw region of the head with blood is the
facial artery which is a branch of the external carotid artery. All blood from the head arises from the common carotid artery wherein it is divided to internal carotid artery (major blood supply of the brain along with the basilar artery on the posterior side) and external carotid artery (major blood supply of the head other than the brain).
The external carotid artery has 8 major branches (from inferior to superior): (1) superior thyroid artery, (2) ascending pharyngeal artery, (3) lingual artery, (4) facial artery, (5) occipital artery, (6) posterior auricular artery, (7) maxillary artery, and (6) superficial temporal artery.
Attached is a simplified photo of the branches of the external carotid artery.
