Georgraphy

Desertification
The clearing of earths forests on a massive scale
Process where weathered material is transported and deposited elsewhere by water, wind and mass wasting
The persistent degradation of dryland ecosystems so that in some cases, areas become desert like
Biosphere
Layer of gases surrounding the Earth, held in place by gravity
The sum of all ecosystems - the life on earth
Human habitat on earth
Cinder cone
Volcanoes which violently eject gas and lava from a single vent in a crater to form a steep circular or oval cone of cinders, simplest type of volcano
Volcanoes with usually symmetrical steep-sided cones made up of alternating layers of lava flows, and solid material ejected under pressure from the volcano
Converging
Process where weathered material is transported and deposited elsewhere by water, wind and mass wasting
Moving towards each other
Dormant volcano
Volcanoes with usually symmetrical steep-sided cones made up of alternating layers of lava flows, and solid material ejected under pressure from the volcano
Volcanoes which violently eject gas and lava from a single vent in a crater to form a steep circular or oval cone of cinders, simplest type of volcano
Volcano that is not currently erupting but is expected to erupt again in the future
Cartographic conventions
Human-made things such as parks, building
BOLTSS
BOLTSS meaning
Contour line
The vertical space between contours, usually indicated in metres
An imaginary line on the ground that joins all places of the same height above sea level
Section of earth where water is solid
Contour interval
The vertical space between contours, usually indicated in metres
An imaginary line on the ground that joins all places of the same height above sea level
Section of earth where water is solid
Degradation
The clearing of Earth's forests on a massive scale
Process where weathered material is transported and deposited elsewhere by water, wind and mass wasting
The deterioration in qualtiy of an object or process. For example, land degredation is the decline in land quality when it becomes unstable
Lava
Fault line
The surface of a fracture forming a fault
The movement of rock along a fracture in the Earths crust
Lahar
Molten rock found within or below the Earths crust
Molten rock or magma that has reached the earths surface
A mixture of volcanic materials and water which then flows downhill
Mudslides
Magma
Molten rock or magma that has reached the earths surface
Molten rock found within or below the Earths crust
A mixture of volcanic materials and water which then flows downhill (mudslides)
Tephra
When water flows along a linear feature causing downward erosion
Process where weathered material is transported and deposited elsewhere by water, wind and mass wasting
A general term for fragments of material that become airborne during volcanic eruption
Pacific ring of fire
A horse-shaped area where several tectonic plates meet around the edge of the Pacific Ocean, resulting in earthquakes and volcanoes
The original supercontinent continent consisted of all land masses before they were split by continental drift
A general term for fragments of material that become airborne during volcanic eruption
Pyroclastic flow
The original supercontinent continent consisted of all land masses before they were split by continental drift
Mixture of hot, solid material of various sizes (from ash to boulders) and gases that erupt from a volcano at high speed
The surface of a fracture forming a fault
Subduction
Broken down rock as a result of weathering
Layer of gases surrounding the Earth, held in place by gravity
Converging of tectonic plates result in one edge of tectonic plates results in one edge of a tectonic plate being forced below the edge of another
Statovolacano
Made up of alternating layers of lava flows, and solid material ejected under pressure from the volcano
Formed by very fluid lava that flows easily resulting in a landform which is very broad at the base and has gentle slopes
Volcano that is not currently erupting but is expected to erupt again in the future
Shield volcano
Made up of alternating layers of lava flows, and solid material ejected under pressure from the volcano
Formed by very fluid lava that flows easily resulting in a landform which is very broad at the base and has gentle slopes
Volcano that is not currently erupting but is expected to erupt again in the future
Name 4 types of natural landscapes
What is a built landscape?
Landforms are types of geographical features. What are four kinds?
How are mountain landscapes formed?
