Erosion is the movement of the broken pieces away from the site of weathering. Basalt columns. For example, a basalt cliff may be weathered by freeze-thaw, a type of physical weathering.This means that pieces of the cliff may break away. Erosion happens when these pieces of rock fall away down the cliff. In the photograph you can see a basalt cliff.rosion is the movement of the broken pieces away from the site of weathering. Basalt columns. For example, a basalt cliff may be weathered by freeze-thaw, a type of physical weathering.
Animals that have a spine are called vertebrates, and animals that don't have one are called invertebrates. Humans have a spine, so we are vertebrates. Many vertebrates, including mammals, have intervertebral discs separating the vertebrae. Regions. The vertebral column is divided by doctors into 5 sections called regions. These 5 regions from top to bottom are: Cervical - Shown in red, this region supports the head. It is made up of 7 vertebrae. The first two, called the atlas and axis, connect the spine to the skull. Thoracic - Shown in blue, this region supports the ribs.
The most important functions of the vertebral column are as follows: 1  Protection: it encloses the spinal cord, shielding it from damage. 2  Support: it carries the weight of the body above the pelvis (below the pelvis, the lower limbs take over).he vertebral arch refers to the lateral and posterior parts of the vertebrae. With the vertebral body, the vertebral arch forms an enclosed hole, called a vertebral foramen. The foramina of the all vertebrae line up to form the vertebral canal, which encloses the spinal cord.
