How are igneous rocks dependent on minerals? How does the water cycle affect the environment? How is phytoplankton part of the carbon cycle? What would most likely happen to the carbon cycle if there were no more plants on Earth? How does water cycle through the biosphere?
Organic sedimentary rocks are one of three kinds of sedimentary rocks; the other two types are clastic and chemical. While clastic sedimentary rocks are made of sediment types of varying size and composition, chemical sedimentary rocks are made of minerals that precipitate from solution. Organic sedi...

Minerals: Minerals are chemical compounds with a specific chemical formula that generally have crystalline structures. They are the basic components of rocks and end up in soil as the rocks erode. Answer and Explanation:1 Minerals will often increase soil productivity because plants need mineral nutri...
What do geologists use to study different minerals that make up a rocks composition? To study the minerals in such a rock, the mineralogist usesa petrographic microscopeconstructed for viewing thin sections of the rock, which are ground uniformly to a thickness of about 0.03 millimetre, in light...
The primary source of the heavy minerals was the igneous鈥攎etamorphic rocks of the Sul-Riograndense Shield and the basalts from Serra Geral Formation. Minerals from these sources were incorporated in the coastal sediments during the Quaternary eustatic changes in sea level and, as the coastal ...
Plant-based meat alternatives can be traced back to the early to mid 1900s. In 1943, Dr. John Harvey Kelloggdeveloped his first “meat analog”made from wheat gluten, soy protein, and minerals. While the product was never commercially produced, it laid the groundwork for future fake meat ...
