A research team has shown that methanogens, micro-organisms ubiquitous in low-oxygen environments like aquifers, soil and even permafrost, can propel their growth by dissolving calcium carbonate, one ...
Earth's ocean absorbs carbon dioxide from the atmosphere, helping to temper the impact of climate change but increasing ocean ...

Why did Earth's greenhouse age end?
Sixty-six million years ago, Earth was a tropical greenhouse. Today, it's an ice-capped world. And an international team of ...
Q. At what level of hydrogen ion concentration in the ocean will the coral reefs and other calcifiers begin to show signs of dissolution? – Submitted by Mackenzie B., 12, Key West, Fl. The hydrogen ...
Scientists have uncovered a surprising mechanism that may explain how Earth cooled dramatically after the age of dinosaurs.
Sea cucumbers secrete acidic compounds that may be weakening the structure of the coral communities in which they live. The main component of a coral reef is calcium carbonate (CaCO3), a mineral that ...
Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes. In Chapter 5, students learned how the process of dissolving ...
A University of Nebraska–Lincoln research team has identified new microscopic players in the global carbon cycle, a discovery that paints a clearer picture of carbon flow through the environment and ...
