What is the Anthropocene Epoch?
In this article, we explain the meaning of ‘Anthropocene’ and why it’s important. We discuss the relationship that humans have with Planet Earth and why
Articles about our world, planet earth: its evolution, biogeochemical cycles, planetary subsystems, atmosphere (inc. ozone layer), biosphere (life), hydrosphere (oceans) & lithosphere (rocks). And The Anthropocene.
In this article, we explain the meaning of ‘Anthropocene’ and why it’s important. We discuss the relationship that humans have with Planet Earth and why
In this article we compress the history of Planet Earth (and the universe) into 365 days. Thirteen billion years are plotted along a single 12-month,
In this article, we answer the question: how much accumulated carbon is stored in each of the major carbon reservoirs? These carbon pools include: the
The oxygen cycle is one of the main biogeochemical cycles transporting vital chemicals through the environmental components of Earth. As usual, there is a fast
The sulfur (sulphur) cycle, one of the major biogeochemical cycles, is a continuous circular process by which sulfur atoms move through the main departments of
The term “biogeochemical cycle” is a massively oversimplified description of a complex, repetitive process in which a chemical is shifted through different physical areas of
The phosphorus cycle is another of the biogeochemical cycles which circulate essential chemicals through the various compartments of Planet Earth, in order to support life.
The nitrogen cycle is one of the biogeochemical cycles that transports vital chemicals through Earth’s various spheres. Other similar pathways include: the carbon cycle, the
The word “troposphere” – from the Greek “tropos” for “turn” or “change” – refers to the layer of air closest to the planet’s surface. It’s
What Is the ‘Atmosphere’? The atmosphere of Planet Earth consists of a layer of gases (mostly nitrogen and oxygen) that we call “air”, held in
The “hydrosphere” is the water component of Planet Earth. It includes (A) all water vapor in the atmosphere; (B) all liquid freshwater and seawater, in
Inside The Goldilocks Zone Planet Earth lies within the so-called “Goldilocks zone” around the sun, where temperatures are “just right” to maintain life. It is
The lithosphere (named after the Greek word “lithos” meaning “rocky”) is the rigid, solid outer layer of the Earth which can extend to a depth
The “pedosphere”, the uppermost level of the lithosphere, is the layer of soil, dust, small stones, sand, silt and other regolith, which covers the Earth’s
The term “water cycle” describes the continuous movement of water within the ecosphere. A vital element in the climate system, it consists of three basic
What Is Ozone? Ozone is a naturally occurring gas that resides in our atmosphere. Each molecule of ozone contains three atoms of oxygen and has
What Is The Carbon Cycle? The “carbon cycle” is one of the most important biogeochemical cycles, operating within Planet Earth. It’s a circular pathway which
