Chemical Weathering JC

What is weathering?

• The classification of rocks.

• The breaking down of rocks.

• The prediction of weather.

• The changing of the weather.

What is Chemical Weathering?

• The processes by which rocks are altered physically.

• The processes by which biology is altered chemically.

• The processes by which rocks are altered chemically.

• The processes by which humans are altered mechanically.

Chemical Weathering is the same as Physical Weathering.

• True

• False

What are the causes of chemical weathering?

• Oxygen, Carbon Monoxide, Water, Acid Rain

• Oxygen, Carbon Dioxide, Water, Rain

• Oxygen, Carbon Monoxide, Water, Rain

• Oxygen, Carbon Dioxide, Water, Acid Rain

CO2 + H2O → H2CO3

• (carbon dioxide) + (water) → (carbonic acid)

• (carbon monoxide) + (water) → (carbonic acid)

Which rock is more prone to chemical weathering

• Limestone

• Marble

• Granite

• Chalk

Chemical weathering occurs when rocks undergo chemical reactions to form ________.

• new materials

• plants

• new rocks

• acid rain

The formation of stalactites and stalagmites in a cave as water mixed with carbon dioxide creates carbonic acid, which dissolves away the limestone, is an example of:

• mechanical weathering
• chemical weathering

What is a Karst Landscape?

• A distinctive landscape made of bare limestone and formed by coastal erosion

• A distinctive landscape made of bare granite and formed by mechanical weathering

• A distinctive landscape made of bare sandstone and formed by chemical weathering

• A distinctive landscape made of limestone and formed by chemical weathering

Where would you find an example of a Karst landscape in Ireland?

• The Wicklow Mountains

• The Giant's Causeway, Co Antrim

• The Burren, Co Clare
