Lesson 1
This energy source, a remnant of early cosmic events and gravitational collapse, helps drive plate tectonics and earthquakes.
What is Earth's Internal Heat? or What is internal heat of Earth?
This is described as molten rock material beneath the surface, including liquids, gases, crystals, and rock fragments.
What is magma?
It a hill or a mountain where lava and gases erupt?
What is a Volcano?
According to this theory, granites are thought to be the oldest precipitates from a primordial sea.
What is Neptunism or Neptunist Theory?
It is the process of changing the characteristics of a rock as a result of changes in temperature, pressure, or reactions with hot fluids.
What is Metamorphism?
This type of heat, resulting from the decay of radioactive elements, contributes to Earth's internal temperature.
What is radiogenic heat?
Magma is formed as temperature increases with depth which is also known as:
What is a geothermal gradient?
This a process where magma rises to the surface of the Earth as lava.
What is Volcanism?
This pertains to a theory that rocks, including granite, were formed by heat-driven processes within Earth’s interior.
What is Plutonism theory?
This term refers to the original rock that undergoes metamorphism to form a new metamorphic rock .
What is protolith?
This refer to the kinetic energy from these cosmic events added to Earth’s internal heat during its formation.
What are extraterrestrial impacts?
This process occurs when pressure decreases, leading to a drop in melting temperatures and partial melting of rock.
What is Adiabatic decompression?
The molten rock that erupts from a volcano and flows onto Earth’s surface in the form of a liquid.
What is Lava?
These structures are formed when rising magma displaces the surrounding host rock as it moves toward Earth's crust
What are plutons?
This process involves the formation of new minerals from the decomposition of old minerals.
What is Neocrystallization?
When Earth formed, gravitational energy from a collapsing dust cloud converted into this form of energy, contributing to Earth’s heat.
What is Gravitational contraction?
These substances evaporate easily and can exist as gases at Earth’s surface, contributing to magma formation.
What are Volatiles?
This type of lava flow is known for its smooth, ropy surface.
What is Pahoehoe lava?
This is a large mass of intrusive igneous bodies with a size of a hundred kilometers in length and width.
What is Batholith?
This refers to the growth of mineral grains of pre-existing minerals.
What is Recrystallization?
This term refers to the measure of heat produced within Earth’s interior and released at its surface.
What is thermal budget?
Enumerate the three classifications of plate boundaries.
What are convergent, divergent, and transform?
This type of lava flow has a jagged and angular appearance
What is aa lava?
This term can be used to classify rocks that formed in the interior of the Earth. This is the opposite of volcanic rocks, which form on the crust.
What is plutonic?
This metamorphic process involves minerals dissolving in areas of high pressure and recrystallizing in areas of low pressure.
What is Pressure Solution?
