4.1 & 4.2 Flashcards
3 examples and location where igneuas rock is found
Granite at the surface of eksdale
Basalt borrowdale
Pumice northern canada
Examples of sedmentry rock and where there found
Chalk in brighton
Limeston dunston head
Difference between metamorphic and igneaus rock
The main difference is that the crystals in an igneous rock is shaped as it crystallized from a melt. The structures in a metamorphic rock are earlier strucures such as crystals, sedimentary fragments, that have been deformed or recrystallized due to heat or pressure, or some chemical change.
Formation of carboniferous limestone
Formed from the remains of organic matter, usually seashells and plants.It was formed under the sea 220-280 million years ago.
Properties of carbonieferous limestone
It is a hard grey sedimentry rock
Whats the compositon grantie usually gives
Red,pink,grey or white colour with dark mineral grains visible throughout the rock
Whats the other name for chalk
cretaceous limestone
Properties of chalk
Soft and white rock
How is chalk formed
Chalk rock a form of limestone if formed in warm, tropical seas about 100 million years ago
Uses of slate
used for roof and floor tiles, and blackboards standard material for the beds of pool / snooker / billiard tables.
How is slate formed
the rocks are heated and put under great pressure. They do not melt, but the minerals they contain are changed chemically
The role of geology
Geologists study Earth processes: Many processes such as landslides, earthquakes, floods, and volcanic eruptions can be hazardous to people.
Name the 2 types of plates
Oceanic plates and continatal plates
Name the upland features
Corrie and U shaped valley
Name the weathiering process in uplands
Freeze thaw makes the ground rocky and conatins angular rocks which is created by the process of freeze thaw weathering
Name the slope processes
Scree fragments are unstable and more easily triggered during rockfall increasing danger for passers by
Effect of ice age
Ice age created deep u shaped valleys they cover most pf tpdags landscape
Explain a glacial trough
Glaciers cut distinctive U-shaped valleys with a flat floor and steep sides. The glacier widens, steepens, deepens and smoothes V-shaped river valleys, eg Great Langdale Valley in the Lake District. The images below show the difference between a U-shaped valley and a V-shaped valley.
Meaning of agriculture
farming, including cultivation of the soil for the growing of crops and the rearing of animals to provide food, wool, and other products.
Meaning of forestery
practice of planting, managing, and caring for forests.
Defention of settlement
is a branch of geography that investigates the earth’s surface’s part settled by humans.
What does climatological weathering mean
weather conditions averaged over a period of time.
Meaning of slope process
slope processes The set of geomorphological processes that act on and below the surface of a hillslope, affecting the regolith and bedrock. Some of the most important are rainwash, sheetwash, weathering, mass movement, piping, and linear erosion by rill and gully activity.
What weathring is found in upland
Freeze thaw weathering
