Formation of sediment Flashcards
What is sediment?
Broken-down material from weathering of rocks
What is the main difference between weathering and erosion?
Weathering breaks down rocks, erosion transports them
Which process is NOT an example of mechanical weathering?
Dissolution
What contributes to chemical weathering?
Carbonic acid from CO₂ and water
What mineral is formed from the hydrolysis of potassium feldspar?
Clay
Why does mechanical weathering enhance chemical weathering?
It increases surface area for reactions
What is a stalactite?
A downward-hanging cave formation from mineral precipitation
What does oxidation in weathering typically affect?
Iron-bearing minerals (e.g., causing rust)
In which climate is chemical weathering most effective?
Warm and moist
Which sediment is the final product of chemically weathered feldspar?
Clay minerals
