Study Notes
Landscapes and Landforms
- Landforms are individual features of the Earth’s surface identified by their shape, such as dunes, plateaus, canyons, beaches, plains, hills, rivers, and valleys.
- Landscapes are a combination of these landforms, geological, geomorphological, biological, and cultural layers that have evolved over time.
- Examples of landscapes include riverine, coastal, and urban landscapes.
- Weathering is the wearing away of the surface of the Earth by the action of wind and water.
- Erosion is the process of eroded material being deposited.
- Constructive forces contribute to the formation of new landforms through volcanic eruptions, tectonic uplift, and the deposition of sediments.
- Destructive forces wear down landforms through weathering and erosion.
- Tectonic plates are large segments of the Earth's crust that move and float.
- Collision plate boundaries occur when two tectonic plates collide.
- The Himalayas mountain range formed as a result of a collision between the Indo-Australian Plate and the Eurasian Plate.
Karst Landscapes
- Karst landscapes are characterized by caves, fissures, and unique environments.
- They form when water infiltrates the Earth's surface and saturates the ground.
- The water table is the upper limit of the zone of saturation.
- Groundwater moves more slowly than surface water, circulating through small spaces within rock or sediment.
- Groundwater contributes to the formation of karst landforms.
- In limestone terrain, bedding and joint planes allow surface water to enter and dissolve calcite, creating caves, springs, and rivers.
- The Nullarbor Plain is the world's largest limestone karst landscape, covering 270,000 square kilometers.
Volcanoes
- Volcanic eruptions can create new landforms or reshape existing ones.
- Tambora, a volcano in Indonesia, erupted in 1815, causing the largest volcanic eruption in historical times.
- Approximately 50 cubic kilometers of dense rock were ejected during the eruption.
- Before the eruption, Tambora stood at about 4,300 meters, but the summit exploded creating a caldera measuring 6 km wide and 1 km deep.
- The eruption released 60 million tons of sulfur, large amounts of fluorine, and massive pumice flows.
- The eruption caused tsunamis, building collapses, and air temperatures to drop dramatically, resulting in a “year without a summer” in 1816.
- The eruption affected global temperatures, causing a drop of up to 3 degrees Celsius.
- At least 71,000 people are estimated to have died during the eruption or immediately afterward.
