Rocks

• • Intrusive igneous rock formed in the magma - Granite.
  • cools very slowly.
  • forms millions of crystals
  • Dublin-Wicklow mountains
  • Counter tops and fireplaces

  
• Basalt

  • Basalt is an extrusive igneous rock.
  • It cools very quickly when lava reaches the surface
  • Basalt has very small crystals.
  • The Giant's Causeway in Antrim.
  • roads
• Sedimentary Rocks :

  They are made up of pieces of other rocks and the remains of dead plants and animals, which over time formed layers (strata)
• • Sandstone was formed when large amounts of sand were worn away from

  the earth's crust. This sand was then carried away by wind or rivers and deposited on the beds of lakes or on the seafloor.

  • in Macgillycuddy's Reeks, Co. Kerry.
  • Tiles and monuments
• Limestone - Limestone is formed when the remains of dead sea creatures, shells and fish bones pile up on the bed of the sea.

  • uses : farming : agriculture lime ,roads and monuments
  • Burren, Co. Clare,
• • Marble is a metamorphic rock. It is formed when limestone is placed under great heat and pressure.
  • headstones,fireplaces, monuments and tiles.
  • White green,red,black.
  • Connemara Galway
• • Quartzite is formed when sandstone comes under great heat and pressure.
  • White
  • uses - watches,in glass,road surfaces

  
• Quartzite - Croagh Patrick County Mayo
• Carringtwohill/Cork The exploit rocks requiring this involves drilling to get rocks Beneath the Earth surface
• An economic impact of exploiting rocks is that it provides the local area employment this may include quarrying itself,driving machinery and repairing equipment this also increases the standards of living for the people getting employed.
• An environmental impact of exploiting rocks is pollution. Air pollution occurs due to the dust from the quarrying, this can affect the health of people in the local area. noise pollution also occurs from the use of machinery and trucks.
• Drilling This is the process of boring down into the earth's crust to extract oil or gas. This can happen on land or out at sea. Reservoirs

  of oil and gas are located underground. When drilling takes place, they are pumped to the surface. Oil and gas are used as fuel sources in cars, homes and industry.
• Quarrying This is the process of removing

  rock, sand, gravel or minerals from the ground.

  Also known as opencast mining, quarrying

  happens at or near the surface of the earth.

  The materials extracted are used by the

  construction industry to build roads and

  buildings.
• Shaft Mining This is the process of drilling vertically into the earth to gain access to minerals

  beneath the surface. Coal, Lead and zinc can be accessed in this way and brought to the surface.
• Oil Spills


  When drilling or transporting oil, there's a risk of spills contaminating soil and water sources, harming aquatic life, and affecting ecosystems
• Climate Change


  Burning fossil fuels like oil and gas emits greenhouse gases, contributing to climate change, rising temperatures, and unpredictable weather patterns
• Job Creation


  The oil and gas industry creates employment opportunities for Irish workers in exploration, drilling, and operation of facilities, stimulating local economies and communities
• Pipeline Construction


  Building pipelines and infrastructure to transport oil and gas resources encourages investment in Irish infrastructure development, improving connectivity and economic growth
• Revenue Generation


  The exploitation of oil and gas resources generates significant revenue for the Irish government through taxes and royalties, contributing to national income and public spending
• • Basalt: Cools very quickly when lava reaches the surface forming small crystals
  • Granite: Magma gets trapped below the surface. Cools very slowly forming large

  crystals
• Limestone.

  1.Remains of dead sea creatures, shells & fish

  bones (sediment) pile up on seabed

  2. Forms layers called strata

  3. Compressed & cemented together over millions of years
• Sandstone:

  1. Large amounts of sand worn away from earth’s crust, carried by wind or rivers

  2. Builds up on beds of lakes or seafloor

  3. Compressed & cemented together
• Quarrying - Milverton, Skerries
