15 Climate Feedback Loops and Examples
Climate feedback loops either amplify or reduce climate change. Positive feedback loops like permafrost melt amplifies climate change because it releases methane.

By dating meteorites, we find the oldest rocks are 4.5 billion or so years old. Thus, we conclude the same staggering 4,543,000,000 years for Earth’s age.
Despite the popular belief that groundwater exists as a huge lake underground, water actually exists in tiny pore spaces within rock and soil beneath our feet.
About 200 million years ago, all the continents were together as one giant supercontinent known as Pangaea. Over time, these continents have broken apart.
From the remarkable process of plates colliding and building mountains. They are only to be dismantled by mass wasting (weathering, erosion and transport).
Biodiversity or “biological diversity” refers to the variety or genetic diversity of species in an ecosystem. Ecosystems rely on biodiversity for resiliency.
Four radioactive isotopes inside Earth account for 50% of its internal heat. Like a slow cooker, they slowly release heat within the planet keeping it warm.
Geotechnical Engineers understand the behavior of earth materials. For example, they interpret rock and soil samples to investigate subsurface conditions.
Carbon is re-purposed into fossil fuels in the long-term carbon cycle. The coal that we use today was produced millions of years ago from buried swamps.
Plate tectonics are deceptively slow. It’s just centimeters each year. Continental drift is the idea that continents passively move due to tectonic activity
Under the rigid layer of rock we live on, the Earth is plastic & more dense. Because of its fluid properties, mantle convection can occur within the Earth.
