Sediments and Sedimentary Rocks Flashcards
To Pass Petrology (36 cards)
Pieces of broken down, pre-existing rocks at or near the Earth’s Surface
Sediments
Rocks that are made-up of lithified Sediments
Sedimentary Rocks
A Sub-branch of Petrology that focuses on the composition. Characteristics and origin of sedimentary rocks.
Sedimentary Petrology
A simple model of the processes responsible for the production of sediments and sedimentary rocks
Sedimentary Cycle
What is the Sequence of Formation
- Weathering
- Erosion
- Transport
- Deposition
5 Diagenesis
Process that breaks down rock into sediments
Weathering
The physical removal of material by mobile agents such as water, wind, ice or gravity
Erosion
What is the strongest agents in terms of weathering
Ice
Weathering that cause by glacier movement
Rock Flour
The Transfer of rock and soil downslope under the influence of gravity
Mass Wasting
3 factors Affecting Weathering
- Climate
- Rock Characteristics
- Differential Weathering
FACTOR AFFECTING WEATHERING:
Factors, particularly temperature and moisture, are crucial to the rate of rock weathering.
Climate
FACTOR AFFECTING WEATHERING:
Chemical Traits of rocks, including mineral composition and solubility
Rock Characteristics
FACTORS AFFECTING WEATHERING:
Unequal weathering due to the rock’s composition
Differential Weathering
A mixture of minerals, organic, matter, water and air.
Soil
The layer of rock fragments produced by weathering
Regolith
The study of physical and chemical properties soils and its formation
Pedology
the soil the can be seen in moon
Regolith
CONTROLS OF SOIL FORMATION:
The source of the weathered mineral matter from which soils develop
Parent material
CONTROLS OF SOIL FORMATION :
Strongly influences weathering by the length of time that processes have been operating
Time
CONTROLS OF SOIL FORMATION:
Climatic elements, such as temperature and precipitation, that exert the strongest impact on soil formation
Climate
CONTROLS OF SOIL FORMATION:
The types of abundance of organism present have a strong influence on the physical and chemical properties of soil.
Organisms
CONTROLS OF SOIL FORMATION:
Variations in topography can lead to the development of a variety of localized soil types
Topography
Zones of soil with varying composition, texture and structure found at different depths.
