What are the factors that cause igneous rocks to break down?
weathering, there are four types of weathering, chemical weathering, caused by acid rain, onion skin weathering, caused by change in temperature eg in the dessert it's boiling at day and freezing at night, freeze-thaw weathering, caused by water freezing and melting, expnding a crack inside a rock, and biological weathering, caused by plants and animals (including humans) eg walking on stone steps again will eventually wear it.
What are the similarities between mechanical weathering and chemical weathering?
Both mechanical weathering (physically breaking rock into smaller pieces) and chemical weathering (chemically changing and even dissolving rock) result in rock layers being broken down. Water can be involved in both - freezing and then thawing lead to mechanical breaking by cracking rock, dissolving can lead to leaching chemical components of the rock, possibly weakening it and leading to pitting of the surface, for example. Also they both can break down some rocks faster than other rocks.
What kind of organism cause the Great potato famine in ireland in the 1800s?
lichen bugs spread the disease
Why do many rocks become rounded?
Erosion and weathering will cause rocks to become rounded.
Changes in pressure which can cause rocks to crack is an example of what?
Changes in pressure which can cause rocks to crack is an example of mechanical weathering. It refers to the disintegration and decomposition of rocks.
What living things attaches to rock and cause chemical weathering?
Lichen.
Does lichen cause chemical weathering?
No, Lichen is caused by clean air meaning where ever there is Lichen in that area the air is clean and not polluted.
How does weathering releases phosphate from rock?
Chemical weathering and physical weathering are two types of weathering involved in the phosphorus cycle. In chemical weathering, a chemical reaction causes phosphate rocks to break down and release phosphate into soil. Acid precipitation and the chemicals released by lichen can cause the chemical weathering. In physical weathering, processes like wind, rain, and freezing releases particles of rock and phosphate into the soil.

What most common cause of chemical weathering?
The most common cause of chemical weathering is oxygen
What is most common cause of chemical weathering?
The most common cause of chemical weathering is oxygen
Do acids cause mechanical weathering?
No, acids cause chemical weathering.
Is water a cause of physical weathering or chemical weathering?
It is a cause of both.
What gas causes chemical weathering?
Oxygen is the major gas that is the cause chemical weathering.
What types of weathering that does not cause chemical changes?
mechanical weathering
Is carbonic acid in water an example of chemical weathering?
Carbon dioxide dissolved in water is a cause of chemical weathering.
What are two agents of chemical weathering?
There are so many agents of chemical weathering. The two main agents that cause chemical weathering are acid rain and carbon dioxide.
