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.
Vertebral column of a goat. The vertebral column, also known as the backbone or spine, is a bony skeletal structure found in vertebrates. It is formed from individual bones called vertebrae (singular: vertebra), which houses the spinal canal, a cavity that encloses and protects the spinal cord.There about 50,000 species of animals that have a vertebral column. The human vertebral column is one of the most-studied examples.ertebrae are defined by the regions of the vertebral column that they occur in. Cervical vertebrae are those in the neck area. With the exception of the two sloth genera (Choloepus and Bradypus) and the manatee genus, (Trichechus), all mammals have seven cervical vertebrae.
