$100 Answer from H 2 Acid Precipitation

$200 Question from H 2 These are agents of chemical weathering (name three)

$300 Question from H 2 What causes acid precipitation

$300 Answer from H 2 The burning of fossil fuels

$400 Question from H 2 a chemical reaction in which an element, such as iron, combines with oxygen to form an oxide. This form of chemical weathering forms rust.

$400 Answer from H 2 Oxidation

$500 Question from H 2 Another name for living things such as algae or fungus (which live on rocks) which produce acids that slowly break down rock.

$500 Answer from H 2 Lichens

$100 Question from H 3 The grinding and wearing away of rock surfaces through the mechanical actions of other rocks or sand particles

$100 Answer from H 3 Abrasion

$200 Question from H 3 These are agents of Mechanical (Physical) Weathering (list at least 4)

$200 Answer from H 3 ice, wind, water, gravity, plants and animals

$300 Question from H 3 An agent of mechanical weathering that causes rocks to fall (rock slide/landslide) causing abrasion as they hit each other

$300 Answer from H 3 Gravity

$400 Question from H 3 When water seeps into cracks during warm weather, temperatures drop, water freezes and expands pushing against the sides of the crack (pressure), widening the crack until the rock breaks up/apart
