Study Notes
Earth Science Study Notes
-
Earth Science is the study of Earth's physical structure, processes, and history.
-
Weathering is the disintegration and decomposition of rocks near the Earth's surface.
-
Physical weathering is the mechanical breakdown of rocks without changing their chemical composition.
-
Chemical weathering involves changes to the molecular structure of rocks and soil.
-
Exfoliation is the process where cracks develop in rock layers due to intense heating and the reduction in pressure from erosion and uplift.
-
Abrasion involves the constant wearing away of rocks by collisions with loose particles.
-
Biological activity includes the role of plants, animals (including humans) as agents of mechanical weathering.
-
Crystal formation, also known as salt wedging, occurs as water evaporates, leaving behind salt crystals that exert pressure on rock fissures.
-
Swiftly flowing water breaks apart rocks through impact with other rocks and sediment.
-
Plant roots can expand cracks in rock, causing breakage.
-
Successive heating and cooling cause rocks to expand and contract, potentially leading to breakage.
-
Frost wedging is a form of physical weathering where repeated freezing and thawing of water in cracks weakens and breaks apart rocks.
-
The rate of weathering depends on factors like the rock's properties, climate, and length of exposure.
-
Soil affects the rate of weathering by retaining water, prolonging chemical reactions.
-
The temperature at which rocks and minerals melt depends on the pressure and the presence of water or carbon dioxide.
-
Magma formation occurs within the Earth's crust due to the melting of rocks.
-
Magma is molten rock below the Earth's surface.
-
Igneous rocks are formed from the cooling and solidifying of magma.
-
Weathering produces rock fragments, which can be transported and deposited elsewhere.
-
Types of magma include basaltic, andesitic, and rhyolitic magmas with different chemical compositions, temperatures and viscosities.
-
Types of volcanoes like Hawaiian and Strombolian.
-
Processes shaping the Earth's surface include weathering, erosion, and deposition.
-
A hot spot is a region within the Earth's mantle that produces magma.
-
The Earth's interior is made up of: a Crust, Mantle, Outer Core, and Inner Core.
-
The temperature and pressure of each layer significantly vary.
-
The Earth's temperature is maintained by heat from when it formed, frictional heating, and radioactive decay.
-
Rocks deform in response to stress, leading to folding, faulting, and fracturing.
-
The processes that form magma by melting of rocks include increase of temperature, decrease of pressure, and the addition of water.
-
Metamorphism is the change in the structure and mineral composition of rock due to pressure, heat, and chemically active fluids.
-
Metamorphic rocks form from existing rocks under different pressure and temperature conditions.
-
Types of metamorphic rocks include foliated (foliation) and non-foliated.
-
Processes causing metamorphism include contact, regional, and dynamic metamorphism.
-
Contact, regional, and dynamic metamorphism are three different types of metamorphism based on different pressure and temperature conditions.
-
Three major types of fault: dip-slip, strike-slip, and oblique-slip faults.
-
Faults are fractures in the Earth’s crust where blocks of rock have moved relative to each other.
-
Types of stress occurring in the Earth's interior include compressive, tensional, and shear stress.
-
Geological structures like folds and faults are produced due to stress and strain.
-
Folds are bends in rock layers while faults are fractures along which the rock has moved.
-
Sedimentary rocks form from pre-existing rocks being weathered, eroded, and transported then deposited in layers.
-
Strata are the layers of sedimentary rocks.
-
Seafloor spreading is a geologic process that occurs at mid-ocean ridges.
-
Plate tectonics is the theory that describes the movement and interaction of Earth's lithospheric plates.
-
Convergent, divergent, and transform plate boundaries are types of plate boundaries with resulting features.
-
Convergent boundaries occur when tectonic plates collide, divergent boundaries occur when plates move away from each other, and transform boundaries occur when plates slide past each other.
-
Relative dating determines the age of rocks by comparing their positions in the rock record while absolute dating determines the actual numerical age of rocks.
-
Index fossils have a known and limited geologic time range, and occurrence in different strata helps determine the ages of rock layers.
-
The geologic time scale divides Earth's history into eons, eras, periods, epochs, and ages.
