Study Notes
Introduction to Earth Science
- Earth science studies the Earth, its components, processes, and history.
- It includes geology, oceanography, meteorology, and astronomy.
- Earth science investigates the planet's structure, composition, and dynamic systems.
Branches of Earth Science
-
Geology: Focuses on Earth's solid materials (rocks, minerals, landforms).
- Studies plate tectonics, volcanic eruptions, and earthquakes.
- Explores Earth's history through fossils and rock formations.
-
Oceanography: Studies the oceans, their properties, currents, waves, tides, and marine life.
- Examines seafloor topography and human impacts.
-
Meteorology: Studies the atmosphere and weather patterns.
- Analyzes clouds, precipitation, storms, and climate.
- Uses models for forecasting and understanding climate change.
-
Astronomy: Studies celestial bodies, including the Sun and its effects on Earth.
- Explores how the solar system's origin and evolution affect Earth.
Earth's Structure
- Earth has layered structures.
-
Core: Central, primarily iron.
- Divided into solid inner core and liquid outer core.
-
Mantle: Surrounds the core, mainly silicate rocks.
- Responsible for convection currents that drive plate tectonics.
-
Crust: Outermost layer, thin compared to others.
- Divided into tectonic plates that move.
-
Core: Central, primarily iron.
Plate Tectonics
- Earth's lithosphere is divided into plates in constant motion.
- Plate interactions cause earthquakes, volcanic eruptions, and mountain building.
- Plate boundaries include divergent, convergent, and transform boundaries.
Earth's Resources
- Earth has natural resources (minerals, fossil fuels, water).
- Earth science helps manage these resources sustainably.
- Resource extraction impacts the environment.
Earth's History
- Earth is billions of years old, evidenced by geological dating and fossils.
- Earth's climate and environment have changed significantly.
- Changes include ice ages, high carbon dioxide periods, and extinctions.
Climate Change
- Climate systems are complex, with natural and human factors.
- Greenhouse gases affect Earth's temperature.
- Human activities increase greenhouse gases.
Natural Disasters
- Earth science helps understand and mitigate natural disaster risks (earthquakes, floods, volcanic eruptions).
- Studying past events helps predict future occurrences and develop mitigation strategies.
