1.3. Types of rocks (flashcards)
What is a cycle?
a cycle is sequences of events that are repeated. For example, this is the cycle to create an igneous rock, the process is the solidification of magma, this is a cycle, an event that repeats and repeats itself.
What is Deposit?
Deposition is an accumulation or layer of solid material, consolidated or unconsolidated, left or deposited by a natural process.
What is Erosion?
Erosion is the geological process in which earth materials wear out and are transported by natural forces such as wind or water.
What is Extrusive process?
Extrusive refers to the mode of igneous volcanic rock formation in which hot magma from within the Earth flows to the surface as lava or explodes violently in the atmosphere to fall as pyroclastics or tuff.
What are Fossil?
Fossils are the remains or signs of the activity of organisms that lived a long time ago, fossil remains are usually one of the main materials of metamorphic rocks.
What are Igneous rock?
Igneous rocks are those that form when magma cools and solidifies. Igneous rocks are one of the 3 rocks that form the core of planet earth, some examples of igneous rocks are diabase, diorite.
What is Intrusive?
Intrusive rock forms when magma penetrates existing rock, crystallizes, and solidifies underground to form intrusions, such as batholiths, dikes, sills, lacoliths, and volcanic necks. Intrusion is one of the two ways igneous rocks can form.
What is lava?
Lava is magma, lava is a molten magmatic material that expels a volcano or the eruption of a volcanic fissure on the earth’s surface where it cools and solidifies.
What is magma
Magma is a mass of molten rock found in the deepest layers of the Earth at very high temperature and pressure, and which can flow out through a volcano.
Metamorphic
Metamorphic things have undergone some kind of transformation or change. … In geology, metamorphic describes a specific process that some rocks undergo when heat and pressure change them.
Metamorphic Rocks
Metamorphic rocks are rocks formed by the modification of other pre-existing ones inside the Earth through a process called metamorphism.
Pressure
Pressure is defined as the physical force exerted on an object. The applied force is perpendicular to the surface of the objects per unit area.
Rock
A rock is a solid material, formed by crystals or grains of one or more minerals.Rocks made up earth crust.
Rock cycle
The rock cycle is a concept used to explain how the three basic types of rocks are related, and how the processes on Earth, over geological time.
Sediment
Sediment is a solid material accumulated on the earth’s surface derived from the actions of phenomena and processes that act in the atmosphere, in the hydrosphere and in the biosphere.
