Rocks

Question 1

Igneous rock

Answer 1

is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.

Question 2

Sedimentary rocks

Answer 2

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth’s surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.

Question 3

Metamorphic rocks

Answer 3

Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Question 4

Basalt

Answer 4

Basalt is an igneous rock.
Basalt is an extrusive rock. Extrusive rocks form when lava reaches the earths surfaces.
As lava spreads out on the surface and meets the air, it cools and hardens very quickly.
Extrusive igneous rocks form small crystals as it cools and so fast basalt is black or grey colour.
This can be found in the Giants Causeway.

Question 5

Limestone

Answer 5

Limestone is a sedimentary rock.
Limestone is formed when the remains of dead sea creatures, shells and fish bones pile up on the sea floor.
The Burren in Co. Clare is a place in Ireland were it is harvested.

Question 6

Sandstone

Answer 6

Sandstone is a sedimentary rock.
It’s formed when large amounts of sand were worn away from the Earths crust.
Sandstone is typically brown in colour.
It can be found in Macgillycuddy’s Reeks Co.Kerry

Question 7

Marble

Answer 7

Marble is a metamorphic rock.
Marble was once limestone but change when magma came into contact with limestone. Marble can very in colour.
Marble can be found in Co. Antrim , Co. Cork, Co. Galway and Co. Kilkenny.
