Types of aerial locomotion Animal aerial locomotion can be divided into two categories - powered and unpowered. In unpowered modes of locomotion‚ the animal uses on aerodynamics forces exerted on the body due to wind or falling through the air. In powered flight‚ the animal uses muscular power to generate aerodynamic forces. Animals using unpowered aerial locomotion cannot maintain altitude and speed due to unopposed drag‚ while animals using powered flight can maintain steady‚ level flight as

Climate Change SUMMARY: Climate change is one of the most contentious public policy go through the world today. While there is just about no argument challenging the matter of the ongoing global warming‚ what is essentially being questioned is whether climate change is anthropogenic or simply a natural‚ cyclical phenomenon upon which human activities do not cast a major impact. This paper will make an effort to compare these two opposing perspectives on climate change. Greenhouse Effect Because

The Pliocene is the fifth epoch of the Cenozoic. The epoch started around five million years ago and lasted almost three and a half million years. It is during the Pliocene that the first bipedal ancestors of humans are known to have evolved. Dramatic cooling and a drop in sea level impacted both marine and terrestrial life at the start of the epoch. The name Pliocene means "more recent” and this were the most recent epoch of Tertiary period‚ lasting from about 5 to 2 million years ago. Compared
