Atmospheric Dynamics, Climate Systems, and Glacial Geomorphology (copy)

Earth System Framework

The integrated system of interconnected spheres representing physical and biological components of Earth.

Atmosphere

The gaseous layer surrounding Earth that drives weather patterns and short-term environmental fluctuations.

Cryosphere

The frozen water system of Earth, including glaciers, ice caps, sea ice, and permafrost.

Pedosphere

The outer layer of Earth composed of soil, subject to soil formation processes.

Biosphere

All biological organisms and living ecosystems on Earth.

Geosphere

The solid lithospheric structure of Earth, involving continental positioning and geology.

Magnetosphere

The magnetic field surrounding Earth that protects the atmosphere from solar radiation.

Anthroposphere

The domain of human modifications to Earth's surface and systems.

Relative Humidity

The percentage of water vapor in the air compared to the maximum amount it can hold before condensation.

Coriolis Effect

The deflecting force on moving air masses due to Earth's rotation, influencing wind patterns.

Jet Streams

High-altitude, high-velocity air currents that separate polar and mid-latitude air masses.

Polar Vortex

A persistent low-pressure system at high altitudes circling the Arctic and Antarctic poles.

El Niño

A climate pattern in the Pacific characterized by warm oceanic thermal shifts and atmospheric changes.

La Niña

A climate pattern in the Pacific characterized by stronger trade winds and colder ocean surface temperatures.

Thermohaline Circulation

The global oceanic conveyor belt driven by temperature and salinity differences in water.

Atlantic Meridional Overturning Circulation (AMOC)

A system of ocean currents that regulates climate in the North Atlantic region.

Glacial Mass Balance

The difference between snow accumulation and ice ablation that determines glacier health.

Glacial Retreat

The process by which glaciers melt back due to ablation exceeding accumulation.

Striations

Scratches or grooves on bedrock caused by moving glaciers.

Moraines

Accumulations of unsorted glacial debris deposited by advancing ice.

Kettle Lakes

Depressions formed when buried ice blocks melt, leaving isolated water bodies.

Glacial Erratics

Large boulders transported and deposited by glaciers from distant geological formations.
