Year 8 - geomorphology

What are beaches?

• Rocky formations formed by erosion

• Shallow, waterlogged areas with emergent vegetation

• Sandy or pebbly shores along the coastline

• Hills or ridges of sand shaped by wind

What causes coastal erosion?

• Wind and rain

• Tectonic activity

• Waves, tides, and currents

• Fluvial processes

What is the main geomorphological force in desert landscapes?

• Fluvial erosion

• Wind erosion

• Glacial erosion

• Coastal erosion

What are stalactites and stalagmites?

• Hills or ridges of sand shaped by wind

• Shallow, waterlogged areas with emergent vegetation

• Flat areas adjacent to rivers subject to periodic flooding

• Formations within caves created by mineral-rich water dripping from the ceiling

What are wetlands?

• Hills or ridges of sand shaped by wind

• Shallow, waterlogged areas with emergent vegetation

• Steep rock faces formed by coastal erosion

• Long, narrow islands parallel to the coast

What is volcanism?

• Wind shapes sand dunes and erodes rock surfaces

• The process of molten rock erupting onto the Earth's surface

• The process of sediment deposition

• The process of weathering rocks through chemical reactions

What is erosion?

• The process of soil deposition

• The process of wearing down and breaking up of rocks

• The process of rock formation through sedimentation

• The process of chemical weathering

What is weathering?

• The process of erosion by wind and water

• The process of rock formation through deposition

• The process of sediment transportation by rivers

• The process of physical and chemical breakdown of rocks

What causes landslides?

• The loosening and displacement of topsoil due to gravity

• Wind erosion

• Glacial erosion

• Tectonic activity

What are endogenic forces?

• Forces that shape coastal landscapes

• Forces originating from outside the Earth's surface

• Forces that draw strength from the interior of the Earth

• Forces that shape desert landscapes
