Tapping of geothermal energy
to produce electricity is done on a larger scale compared to the tapping of
the geothermal gradient using a geothermal heat pump. Harnessing geothermal energy is also reliant on geological conditions such as in the area
of convection boundaries while geothermal
gradient can be harnessed virtually
anywhere on the earth surface.
Answer: Low population density Tend to decrease birth rates and increase mortality rates.
Explanation:
The vertebral column, when seen from the side, has 4 curves: 2 convex curves (cervical and lumbar curves) and 2 concave (thoracic and sacral curves). This curves are the feature of the skeleton that allow a child to maintain balance in the upright position eventually.
When we are born we have a single concave curve throughout the whole vertebral column but, as we grow, still in the early months as we try to hold our head, the cervical curve starts to develop, and later, as we try to sit up, stand up, and walk, the lumbar curve aslo starts to develop. In few years we have all curves fully developed.
The answer is energy, I think
