Certain gases, known as greenhouse gases, let sunlight shine directly onto the Earth’s surface but also capture the heat reflected into the atmosphere. Too much carbon dioxide

What Is The Mariana Trench?

The Mariana Trench is a deep point in the ocean and one of the largest crescent-shaped trenches on the surface of the Earth. It contains the only known ventilation point where liquid sulfur and carbon dioxide from the vents inflow, an important source of oxygen to which marine life can adapt. Depth is difficult to

What Is Alveoli?

The alveoli are balloons – like air sacs that hang at the distal end of the bronchial tree. However, they are most commonly used to describe the smallest of all air sacs in the lungs of mammals, and are therefore more accurately known as pulmonary alvoli. Consequently, there are different names for the different types

What Is Ocean Acidification?

It is the increasing amount of carbon dioxide in the ocean that is acidifying the oceans. As a result, since the Industrial Revolution (around 1750), the oceans have absorbed large amounts of this carbon dioxide, and it is therefore acidifying. When carbon dioxide enters the oceans, it combines with seawater to form carbonic acid, which
