APES Unit 4 Slides

The course offers an exclusive 9-unit video review series.
Includes guided notes, unit quizzes, and extra math practice.
Students receive two full-length practice exams and answer keys for all materials.
Comprehensive preparation is essential for passing APES tests and the exam scheduled for May 3rd.
A link to the APES Ultimate Review Packet is available for deeper insights.

Unit 4 of the review focuses on Earth Systems.

Convergent boundaries lead to mountain creation, earthquakes, and volcanoes.
Divergent boundaries are responsible for seafloor spreading and rift valleys.
Transform boundaries result in earthquakes, with an emphasis on fault movement.
Visual representations of plate boundaries can help determine the location of geological events such as volcanoes and earthquakes.

Core: Composed of a dense mass of solid nickel, iron, and radioactive elements, releasing significant heat.
Mantle: Aliquid layer of magma that surrounds the core, maintained in a liquid state by the core's heat.
Asthenosphere: A flexible, solid upper mantle layer beneath the lithosphere.
Lithosphere: A thin, brittle layer of rock divided into tectonic plates that floats atop the mantle.
Crust: The outermost layer and surface of the earth.

Occur when plates move apart, allowing rising magma to create mid-ocean ridges and rift valleys.
Associated geological formations include volcanoes and earthquakes.

Plates move towards each other; one may be subducted under the other.
Result in the formation of mountains (e.g., the Himalayas), island arcs, and related geological activities such as earthquakes and volcanoes.

Plates slide past each other, leading to significant earthquake activity as pressure builds along rough edges and is eventually released.

Rising magma heats up the lithosphere, creating mid-ocean ridges and seafloor spreading.
Convection currents are critical for the movement of tectonic plates and can lead to the formation of mountain ranges like the Andes due to subduction.

An earthquake results from the sudden release of energy caused by stress overcoming a fault lock.
Maps displaying plate boundaries help predict the location of seismic activity.

Soil consists of geological and organic components, including various particle sizes such as sand, silt, and clay, along with nutrients essential for plant growth.
Key soil constituents include humus, which is derived from decomposed organic matter, and water, which plays a vital role in nutrient absorption.

Weathering: The breakdown of rocks into smaller particles through physical, biological, or chemical means.
Erosion: The process of transporting these particles to new locations, where they can accumulate and form new soil layers.

The soil profile is made up of layers, including the O-horizon (organic matter), A-horizon (topsoil rich in humus), B-horizon (subsoil with accumulated minerals), and C-horizon (weathered parent material).

Factors influencing soil quality include compaction, nutrient depletion from repeated use, and the presence of organic matter.
Nutrient retention and water-holding capacity are crucial for determining soil fertility and supporting plant growth.

A watershed is an area that drains into a specific body of water and is influenced by surrounding geography, such as soil and vegetation.
The health of watersheds is vital since they filter pollutants and support ecosystems.
Human activities, such as agriculture and urban development, significantly impact water quality within these regions.

The Chesapeake Bay watershed is crucial for its ecological and economic importance, supporting diverse species and offering recreational activities.
Pollution from nutrient runoff leads to issues like eutrophication, affecting aquatic life and water quality.

Insolation, the amount of solar energy reaching the earth, varies with latitude and is dependent on the angle of sunlight.
The Earth’s tilt affects seasonality, influencing temperature and climate patterns globally.

Albedo refers to the reflectivity of surfaces; higher albedo (like ice) reflects more light and absorbs less heat, affecting surface temperatures significantly.

Local geography, including mountains and oceans, plays a pivotal role in influencing weather patterns and climate via mechanisms like the rain shadow effect.

Understanding these key concepts provides a foundation for success in AP Environmental Science, preparing students for exam scenarios and real-world environmental applications.
