Rocks and Landscapes

Igneous Rocks originate from magma in the mantle, can be extrusive or intrusive.
Extrusive Rocks formed by being thrown out during a volcanic eruption.
Intrusive Rocks formed under the surface of the Earth.
Sedimentary Rocks small sediments accumulate on sea floors in layers and compress over millions of years.
Metamorphic Rocks rocks that have changed in shape or form, by heat/pressure. Can be igneous/sedimentary rocks.
Freeze Thaw water enters cracks in rock during day, overnight temperatures drop and water freezes, as it freezes it expands, cracking the rock.
Exfoliation heating of outer layer of rock during day, causing expansion, at night rock contracts. Expanding and contracting leads to layers of rock pealing away.
Hydrolysis dissolves and disintegrates rock.
Chalk called cretaceous limestone. An example of porous rock.
Clay product of weathering and river erosion. Porous and becomes impermeable when wet.

Coasts

Waves formed by wind blowing across surface of the water, creating ripples, which grow into waves.
Fetch determines how powerful a wave may be. It is the distance that the wave has travelled.
Destructive Waves stronger backwash than swash, removes material from the beach.

Glaciers

Glaciers originate from heavy snowfalls over a prolonged period of time.

Accumulation build up of the glacier due to snow being compacted into ice.
Calving splitting of the end of the glacier into smaller sections.
Ice Sheets large masses of ice, which cover an entire land surface.

Weather & Climate

Climate describes temperature, precipitation and other weather conditions of a certain area.
Weather describes day-to-day changes in temperature, wind and precipitation.
Altitude temperature falls the higher you are.
Distance From Sea sea takes longer to heat up but retains that heat far better than the land.
Latitude lines of latitude are those that run horizontally around the world.
Ocean Currents affect areas beside the sea. Can be either warm or cold currents.
Prevailing Winds when travels over a warm surface will bring warm weather, if it travels over a cold surface will bring cold weather.
Climate Graphs useful in comparing annual temperature and rainfall of places around the world.
Rainfall plotted on climate graphs as a bar chart, coloured blue.
Temperature plotted on the climate graph as a line graph, coloured red.
Convectional Rainfall occurs when warm land surfaces heats air above it, causing it to rise, cool and condense.
Frontal Rainfall occurs when two air masses meet, with warmer air being forced to rise over cooler air. The rising air cools and condenses.
Relief Rainfall occurs when moist air reaches the coast and is forced to rise over mountains and hills. The rising air cools and condenses.
Depressions areas of low pressure that bring clouds and rain to the UK.
Anticyclones areas of high pressure. Bring warm, stable conditions, with clear skies and lots of sunshine.
Droughts below average rainfall for a period of time, causing water supplies to dry up and run out.
Tropical Storms known as hurricanes, cyclones, typhoons, and willy willies.
Global Warming heating of the atmosphere due to release of greenhouse gases.
Carbon Dioxide produced by power stations, vehicles, and animals breathing.
Ozone gas in the atmosphere that prevents harmful ultra-violet rays from affecting us.

Ecosystems

Ecosystems entire living communities of plants and animals.
Abiotic elements that are non-living.
Biotic elements that are living.
Producers organisms within the biotic element, convert sunlight into energy through the process of photosynthesis.
Consumers organisms within the biotic element, which feed on other organisms.
Coniferous (Boreal) Woodlands coniferous trees are evergreens; they have leaves all year round and therefore can always photosynthesise
Deciduous Woodland deciduous trees drop their leaves in the autumn.
Deserts soils are alkaline and are very dry with little humus.
Tropical Rainforests soils are called latsols. Boast a huge variety of vegetation and animal life.
