The Caribbean Landscape, Rock Types, and Human Activities

Comprehensive vocabulary flashcards covering Caribbean rock types, geological formations, topography, and the direct and indirect impacts of human activities on the Caribbean landscape.

Topography

The physical features of an area of land, including mountains, valleys, plains, rivers, plateaus, and coastlines, which influence settlement, communication, and economic activities.

Landscape

The visible features of an area of land, such as mountains, rivers, forests, or plains.

Caribbean Landscape

The physical features of the Caribbean region, encompassing islands, beaches, mountains, valleys, and coral reefs.

Human Activity

Actions carried out by people that affect the environment or society, such as farming, fishing, building, mining, or tourism.

Direct Impacts

Immediate and visible changes to the landscape resulting from human actions, such as mining, farming, and building construction.

Indirect Impacts

Less obvious, delayed environmental consequences of human activities that manifest over time, such as climate change and accelerated erosion.

Weathering

The natural process of breaking down existing rocks into smaller particles or sediments through the action of wind, water, or ice.

Rock Cycle

The continuous natural cycle showing how igneous, sedimentary, and metamorphic rocks transform into one another through melting, cooling, weathering, erosion, deposition, compaction, and heat and pressure.

Topsoil

The outermost layer of soil formed from weathered rock that contains minerals, water, air, and organic matter, crucial for supporting plant life.

Subsoil

The soil layer situated directly beneath topsoil, characterized by fewer organic materials and a higher proportion of minerals.

Igneous Rocks

Rocks formed from the cooling and solidification of molten rock (magma underground or lava on the surface), featuring a hard, crystalline texture without layers or fossils.

Intrusive Igneous Rocks (Plutonic)

Igneous rocks formed when magma cools very slowly deep underground over thousands to millions of years, producing a coarse-grained texture with large, visible crystals (e.g., granite, diorite, gabbro, peridotite).

Extrusive Igneous Rocks (Volcanic)

Igneous rocks formed when lava cools rapidly on or near the Earth's surface in minutes to days, resulting in fine-grained, glassy, or porous textures with trapped gas bubbles (e.g., basalt, andesite, obsidian, pumice).

Sedimentary Rocks

Rocks formed on or near Earth's surface through the accumulation, compaction, and cementation of mineral sediments, rock fragments, or biological remains, typically exhibiting distinct strata and fossils.

Clastic Sedimentary Rocks

Sedimentary rocks made from compressed fragments (clasts) of pre-existing rocks, categorized by particle size, such as sandstone (sand-sized grains), shale/mudstone (clay/mud particles), and conglomerate (rounded pebbles/boulders).

Chemical Sedimentary Rocks

Sedimentary rocks formed from dissolved mineral compounds that precipitate directly out of water, including rock salt, chert, and certain types of limestone.

Organic (Biologic) Sedimentary Rocks

Sedimentary rocks formed from the compacted and cemented organic remains of living organisms, such as coal from decayed plants and chalk from microscopic shells.

Metamorphic Rocks

Rocks formed when pre-existing parent rocks (protoliths) are altered by intense heat, pressure, and chemically active fluids deep within the Earth without melting, recrystallizing into new minerals and textures.

Foliated Metamorphic Rocks

Metamorphic rocks displaying parallel mineral alignment that creates distinct bands or layered textures under directed pressure, including slate, phyllite, schist, and gneiss.

Non-Foliated Metamorphic Rocks

Metamorphic rocks with a massive, granular crystalline texture lacking visible layers or banding, including marble, quartzite, hornfels, and anthracite coal.

Bauxite

An aluminum-bearing sedimentary ore found in Jamaica and Guyana, extracted to manufacture aluminum products ranging from kitchen foil to airplanes.

Gypsum

A sedimentary mineral rock extracted in Barbados, Trinidad, Jamaica, and the Dominican Republic, used in the manufacturing of plaster, cement, and soil conditioner.

Limestone

A dominant Caribbean sedimentary carbonate rock found in Jamaica, The Bahamas, and Barbados, utilized in construction, cement production, and lime manufacturing.

Basalt

A dense, fine-grained extrusive igneous rock found in Dominica, St. Vincent, and Montserrat, utilized for road construction, aggregate, and building materials.

Andesite

An extrusive igneous rock found in St. Lucia, Martinique, and Montserrat, primarily used for concrete production and construction aggregate.

Diorite

An intrusive igneous rock found in the Virgin Islands and Montserrat, utilized in general construction, road base, and aggregates.

Granite

A coarse-grained intrusive igneous rock found in Jamaica and the British Virgin Islands, used for construction and decorative stone.

Gneiss

A high-grade foliated metamorphic rock with alternating dark and light mineral bands, located in the Virgin Islands, Dominican Republic, and Haiti, utilized as decorative and building stone.

Quartzite

A non-foliated metamorphic rock created by quartz grains fused from sandstone, found in the Dominican Republic, and used for countertops, flooring, pavements, and wall coverings.

Schist

A medium-grained foliated metamorphic rock rich in visible mica flakes, found in the Dominican Republic, Haiti, and Cuba, used for construction and decorative stone.

Marble

A non-foliated metamorphic rock formed from recrystallized limestone or dolostone, found in Jamaica and Cuba, utilized for sculptures, flooring, and architectural countertops.

St. Catherine Plains

A flat, fertile region in Jamaica that supports large-scale agricultural operations, specifically the cultivation of sugarcane and bananas.

Blue Mountains

A rugged mountain range in Jamaica with steep terrain that limits human settlement and road construction, famous for coffee farming and eco-tourism.

Ocho Rios

A growing resort town on Jamaica's northern coast whose flat coastal topography, road connections, and cruise ship port enable tourism at sites like Dunn's River Falls and Dolphin Cove.

Cockpit Country

A biologically diverse forest and karst landscape in Jamaica hosting rare plants and animals, threatened by deforestation from logging, agriculture, and mining.

Negril

A Jamaican resort area where coastal development, pollution, and climate change have caused severe beach erosion, resulting in a shoreline loss of $23.4\,\text{m}$ since $1968$.

Dredging

The process of excavating sand and mud from the seabed, which causes coastal water pollution and damages coral reef ecosystems during harbour or resort expansion.

Bogue Lagoon

A vital mangrove wetland area in Montego Bay, Jamaica, that serves as a natural barrier to absorb wave energy, reduce storm damage, and filter coastal pollutants.

Environmental Audits for Sustainable Tourism (EAST)

A program in Jamaica designed to help hotels and resorts lower their environmental impact by minimizing waste and conserving water and energy.

Jamaica Inn Coral Reef Restoration Project

An ecological restoration initiative in Jamaica working to rebuild damaged coral reefs to protect marine life and stabilize coastlines against erosion.
