the average weather conditions in An area over a long period of time$100 Question from H1 the average weather conditions in An area over a long period of time
$100 Answer from H1 Climate (Temperature)
$200 Question from H1 The height (typically measured in feet above sea level) to which something is elevated or to which it rises
$200 Answer from H1 Elevation
$300 Question from H1 The more _______ _____ of a rock that is exposed to weathering, the faster the rock will wear down.
$300 Answer from H1 Surface Area
$400 Question from H1 Rocks that are made of ______ minerals will weather faster than rocks that are made of _______ minerals.
$400 Answer from H1 Softer, harder
$500 Question from H1 A process by which softer, less-weather resistant rock wear away and leave harder, more weather-resistant rock is called…
Differential Weathering$500 Answer from H1 Differential Weathering
$100 Question from H2 Rain, snow or sleet that contains a high concentration of acids (an agent of chemical weathering)
$100 Answer from H2 Acid Precipitation
These are agents of chemical weathering (name three)$200 Question from H2 These are agents of chemical weathering (name three)
$200 Answer from H2 Water, weak acids/plant Acids, air
What causes acid precipitation$300 Question from H2 What causes acid precipitation
$300 Answer from H2 The burning of fossil fuels
$400 Question from H2 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 H2 Oxidation
$500 Question from H2 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 H2 Lichens
$100 Question from H3 The grinding and wearing away of rock surfaces through the mechanical actions of other rocks or sand particles
$100 Answer from H3 Abrasion
These are agents of Mechanical (Physical) Weathering (list at least 4)$200 Question from H3 These are agents of Mechanical (Physical) Weathering (list at least 4)
$200 Answer from H3 ice, wind, water, gravity, plants and animals
$300 Question from H3 An agent of mechanical weathering that causes rocks to fall (rock slide/landslide) causing abrasion as they hit each other
$300 Answer from H3 Gravity
$400 Question from H3 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
$400 Answer from H3 Ice Wedging
$500 Question from H3 Describes how a rock changes after it has been in a riverbed for a long time
$500 Answer from H3 the edges of the rock are worn away and its surface becomes smoother
$100 Question from H4 The process by which wind, water, ice or gravity transports soil and sediment from one location to another
$100 Answer from H4 Erosion
$200 Question from H4 The process in which material/minerals are laid down after being carried away
$200 Answer from H4 Deposition
$300 Question from H4 The process by which rock materials are broken down by the action of physical or chemical processes

I will only call on 3 of you to share
Weathering, and Soil Formation
Weathering: The natural process by which atmosphere and environmental forces, such as wind, rain, and temperature changes, disintegrate and decompose.
Physical (Mechanical) Weathering
Weathering and Erosion Weathering means the process of breaking down rocks and other substances at Earth’s surface.
The Earth’s Changing Surface
