Sulcus The extra bones that sometimes develop between the flat bones of the skull are called bones. Small bones occurring in some tendons in the hand or foot are called bones. The cranium and facial bones compose the . The bone supports the tongue. The at the inferior end of the sacrum is composed of several fused vertebrae. Most ribs are attached anteriorly to the .

Type of Bones

Explanation:

Sutures are a type of fibrous joint that binds two bones together into a solid, immobile expanse of bone. We are most familiar with sutures in the skull that connect the different cranial bones  Sesamoid bones are small bones embedded in tendons where they pass over a joint. The most prominent sesamoid bone is the kneecap, officially known as the patella. tSurrounding your brain is the part of your skeleton known as your skull. Your skull is made of bone and cartilage, or firm tissue; its job is to protect your brain. Some of the bones surrounding the brain, and some of the bones are facial bones. Facial bones are bones like the jaw and cheekbonesThe hyoid bone is small, U-shaped bone in the throat. It is located in the front, middle of the throat between the lower jaw and the larynx, which is also called the voice box. The hyoid bone is involved in several functions of the throat, including breathing, swallowing, and talkingThe coccyx is a small bone at the base of your spine.Our spines are made up of 24 small bones in our back that support the weight of our bodyThe sternum is one of the largest flat bones in the human body. It located in the center of the chest, which is why it is often called the breastbone

What are the answers

Mantle convection  is the slow  creepingmotion of earth's solid silicate  mantle  caused by  convection  currents carrying  heat from the interior  to the planet's surface.[1][2]  the earth's surface  lithosphere, which rides atop the  asthenosphere  (the two components of the  upper mantle), is divided into a number of  plates  that are continuously being created and consumed at their opposite  plate boundaries. accretion occurs as mantle is added to the growing edges of a plate, associated with  seafloor spreading. this hot added material cools down by  conduction  and  convection  of heat. at the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of  subduction  usually at an  ocean trench.[3]this subducted material sinks through the earth's interior. some subducted material appears to reach the lower mantle,[4]  while in other regions, this material is impeded from sinking further, possibly due to a phase transition from  spinel  to  silicate perovskiteand  magnesiowustite, an  endothermic reaction.[5]the subducted oceanic crust triggers  volcanism, although the basic mechanisms are varied. volcanism may occur due to processes that add buoyancy to partially melted mantle causing an upward flow due to a decrease in density of the partial melt.secondary forms of convection that may result in surface volcanism are postulated to occur as a consequence of intraplate extension[6]  and  mantle plumes.[7]it is because the mantle can convect that the  tectonic plates  are able to move around the earth's surface.[8]mantle convection seems to have been much more active during the  hadean  period, resulting in gravitational sorting of heavier molten  iron, and  nickel  elements and  sulphides  in the core, and lighter  silicate minerals  in the  mantle.
