Q

What is freeze thow action

A

The break up of rock by frost action. By day water goes info the cracks if the rocks. By night it freezes and expands. Over time it continues and causes the rock to brake off

Q

What is carbonation

A

Carbonation occurs because carbon dioxide mixes with the rainwater forming a weak carbonic acid
The acid reaches with the calcium in the rock to make it to dissolve slowly

Q

How is a stalagmite made

A

When drops of water drip from the stalactite fall onto the floor and evaporate they also deposited calcite that grows upwards

15
Q

What is a stalictight how is it formed

A

When calcium carbonate runs down the rock and dissolves it leaving calcite to make drops from the roof of the cave

16
Q

What are pillars/columns

A

When stalagmites and stalictight join together

17
Q

What does transported mean

A

The removal of the particles of rocks being moved by water,wind,ice

18
Q

What does deposited mean

A

The particles of the rocks have moved somewhere else

19
Q

What is mechanical weathering

A

Is a type of weathering that causes rock to brake up into smaller pieces

20
Q

What is chemical al weathering

A

A type of weathering that causes rocks to decay or dissolve because of a chemical change

21
Q

What does permeable mean

A

The water can go through it

22
Q

What is a swallow hole and how is it made

A

It is made when rivers flow onto a bare limestone surface and dissolves the limestone. The water widens the joints and bedding planes opening them up so the water can run through tune river disappears from the surface nod runs underground

23
Q

What is a stalactite and how is it formed

A

When calcium carbonate runs down through the rock t dissolves leaving calcite which makes drops coming from the roof which. Builds up over years

24
Q

How is a cave formed

A

As the river flows along flows underground( fro. The swallow hholes) the carbonic acid in the water dissolves the limestone leaving long tunnels called caves

25
Q

What is a cavern

A

Sometimes when caves get very big they form a big chamber called a cavern

26
Q

What is the burren

A

The burren is a large karst region in west co. Clare known for its flora,fauna,landscape and history

27
Q

What is flora

A

Plants

28
Q

What is fauna

A

Animals

29
Q

What does chemical weathering do

A

Dissolve rocks

30
Q

What does permeable mean

A

Water easily passes through

31
Q

What are joint
