Geoscience Data

Back

Information collected from Earth’s systems, including climate data, satellite imagery, and geological surveys, used to analyze and understand natural processes and changes on Earth.

Front

Feedbacks

Back

Processes in which a change in one part of Earth's system causes effects that influence that same part, either amplifying (positive feedback) or diminishing (negative feedback) the original change.

Front

Climate Feedbacks

Back

Interactions within the climate system where a change, like increased greenhouse gases, leads to further changes that can amplify or reduce the initial effect, such as the melting of glacial ice leading to more warming.

Front

Greenhouse Gases

Back

Gases like carbon dioxide and methane that trap heat in Earth’s atmosphere, contributing to global warming and climate change.

Front

System Interactions

Back

The ways in which different components of Earth's systems (like the atmosphere, hydrosphere, and biosphere) interact and influence each other, often leading to feedback effects.

Front

Dammed Rivers

Back

Rivers that have been blocked by dams, altering natural water flow, increasing groundwater recharge, reducing sediment transport, and affecting coastal erosion.

Front

Groundwater Recharge

Back

The process by which water from precipitation or rivers seeps into the ground to replenish underground aquifers, which can be affected by human activities like damming rivers.

Front

Earth's Interior

Back

The internal structure of Earth, composed of concentric layers—crust, mantle, outer core, and inner core—each with distinct physical and chemical properties.

Front

Cycling of Matter

Back

The continuous movement of materials within Earth's interior, driven by thermal convection, which moves rock and minerals through different layers.

Front

Radial Layers

Back

The concentric layers of Earth, arranged by density and composition, including the crust, mantle, outer core, and inner core.
