There are some very key items that go into the soil that everyone walks on. The first thing, what is soil made from. Soil is actually broken up rock sediments and decomposed plants and animals. But what gives soil its texture? That also comes from...
Symbiosis between coral reefs and algae
By: Jose Juan Gutierrez
Coral reefs are sea water structures made of calcium carbonate (CaCO3) secreted by living organisms. Thousands of organisms thrive in coral reef ecosystems; however, only a small fraction manufactures the limestone required to build coral reefs. Stony (hermatypic) corals are one type of corals responsible...

What happens to life on earth if soil all over the globe erodes away faster than nature can replace it? Disaster is perhaps too mild a word, since food production allows human life, and all non-human life depends also upon soil. Preventing erosion and using...

Estuaries are some of the most unique and diversified ecosystems in the world. Found along coastal regions where salt water coming in from the sea during tides mixes with freshwater entering the ocean. The result is a unique system that is a critical habitat for...
Why estuaries might be endangered
By: Kimberly Napier
Estuaries help the world in many ways. The Ohio State University states that they are areas of breeding for animals that live in deeper waters; they provide homes and feeding grounds for a variety of animals; they are an area where the basic needs of...
What is a coral reef ecosystem?
By: Jose Juan Gutierrez
A coral reef ecosystem consists of marine structures made of calcium carbonate secreted by living organisms. Most coral reefs are built by stony corals. Stony corals consist of hundreds of thousands of small animals known as polyps that form colonies on the reefs. The coral...

When examining a soil profile, scientists look at the different soil horizons, or the layers of soil or the soil's materials which, to some degree, parallel the land surface. There are differences in the different horizons like color, structure, texture and consistency, as well as...
How human activity affects erosion
By: John Mmbaga
Erosion is the process by which rock and soil are removed from the surface of the Earth as a result of water and wind action and thereafter deposited to other areas on the Earth’s surface. While erosion is a naturally occurring process, human activity...

An estuary is a coastal ecosystem, typically consisting of a body of brackish water that is supplied by inflows of fresh water from rivers and streams that mix with the ocean's salty water. Estuaries provide a natural habitat between ocean waters and fresh waters. The...
Is a coral reef plant or animal?
By: Jose Juan Gutierrez
Coral reefs are marine structures made up of tiny animals called polyps. These marine structures are made of limestone which is deposited by coral polyps on layer upon layer, eventually forming reefs. Upon completing their life cycle, coral polyps leave out their limestone shell skeletons...
