WebThe Rock Cycle Rocks are constantly changing in what is called the rock cycle. It takes millions of years for rocks to change. Here is an example of the rock cycle describing how … WebThe rock cycle describes how the three main rock types—igneous, sedimentary, and metamorphic—change from one type to another. These changes occur through processes such as melting, solidification, and lithification. The rock cycle is driven by energy from Earth's interior and the sun. Created by Khan Academy.

The gold cycle is the biogeochemical cycling of gold through the lithosphere, hydrosphere, atmosphere, and biosphere. Gold is a noble transition metal that is highly mobile in the environment and subject to biogeochemical cycling, driven largely by microorganisms. Gold undergoes processes of … See more The lithosphere is the dominant reservoir of gold, containing an estimated 2.6x10 Mg. Today, gold exists primarily as electrum, in hard rock deposits like tellurides, and as particles in placers in Earth's crust. Gold … See more The atmosphere is the smallest reservoir of gold, containing an estimated 370 Mg. The most volatile gold compounds are Au2Cl6, which may occur in volcanic gases, and AuF3. See more Throughout Earth's history, the interplay of gold, microorganisms, and physicochemical conditions such as pH and redox potential have led to the aggregation of gold particles to form grains and nuggets. Cyanobacteria in shallow surface … See more The ocean reservoir contains an estimated 5.6x10 Mg of gold and oceanic gold concentration is about 4 ng Au/L with higher values in some coastal waters. Au(I/III)-ions and Au(0)-colloids are unstable under surface conditions in aqueous solutions … See more The biogeochemical cycle of gold is affected by the carbon, nitrogen, sulfur, and iron cycles. Decomposition of organic carbon under anoxic … See more • California Gold Rush • Biogeochemical cycle See more WebUnderstand: the rock cycle. NGSS.MS: MS‑ESS2‑1, MS‑ESS2.A.1. Google Classroom.
