What is the geologic cycle?
geological cycle. The continuous process in which hot, molten material coming to the surface of the Earth from the interior forms igneous rocks, which are then broken down by weathering to create soil and sedimentary rocks.
What are 5 geological processes?
Geological processes – volcanoes, earthquakes, rock cycle, landslides Plate boundaries include transform, convergent , divergent.
What is the importance of geological processes?
Geologists study Earth processes: Many processes such as landslides, earthquakes, floods, and volcanic eruptions can be hazardous to people. Geologists work to understand these processes well enough to avoid building important structures where they might be damaged.
What are geological features?
The term can be defined as any physical feature of the earth’s surface – or of the rocks exposed at the surface – that is formed by a geologic process. Many geologic features influence the shape of the ground’s surface and can be described by the perhaps more familiar terms topography, landscapes, or landforms.
What do these three geological processes?
Geologic Processes Melting – responsible for creating magmas that result in volcanism. Deformation – responsible for earthquakes, volcanism, landslides, subsidence. Isostatic Adjustment due to buoyancy – responsible for earthquakes, landslides, subsidence. Weathering – responsible for landslides, subsidence.
What is geology and its importance?
Geology is the study of the Earth – how it works and its 4.5 billion-year history. Geologists study some of society’s most important problems, such as energy, water, and mineral resources; the environment; climate change; and natural hazards like landslides, volcanoes, earthquakes, and floods.
Who are famous geologists?
PEOPLE KNOWN FOR: geology

What are geological materials?
Definition: A geological material is a material extracted as-is from the earth in rock or sediment form, including rocks, clays, sands, limestone, and other industrial minerals.
What is the root word of Geological?
The Greek root word ge, commonly used in the English prefix geo-, means “earth.” This Greek root is the word origin of a good number of English vocabulary words, including geology, geography, and geometry.
What is geological setting?
The age of the geologic units decreases from west to east. The oldest rocks are mostly Cretaceous and Jurassic marine limestone, sandstone, shale, and evaporite units with a complex history of folding.
Why would the geologic setting in this figure cause metamorphism?
why could the geologic setting in this figure cause metamorphism? because it forces some rocks deeper as they are overridden by rocks above the fault.
What is the difference between geologic and geological?
As adjectives the difference between geologic and geological is that geologic is of, or relating to geology or a geologic timescale while geological is geologic.
What is the difference between geology and etymology?
is that geology is the science that studies the structure of the earth (or other planets), together with its origin and development, especially by examination of its rocks while etymology is (uncountable) the study of the historical development of languages, particularly as manifested in individual words.
What are examples of geological hazards?
Definition: A geologic hazard is an extreme natural events in the crust of the earth that pose a threat to life and property, for example, earthquakes, volcanic eruptions, tsunamis (tidal waves) and landslides.
What are the two types of geological hazard?
Landslides of all kinds, including seismically-triggered landslides, debris flows, mud flows, and rock falls. Mineral hazards such as asbestos, radon, and mercury. Volcanic hazards, such as ash fall, lava flows, lahars, pyroclastic flows, toxic gases, and volcanic landslides.
What are the four geological hazards?
- Earthquakes – Liquefaction (soils), Tsunamis.
- Volcanic Eruptions – Lava Flows, Ash Fall, Lahars.
- Landslides – Rock Falls or Slides, Debris Flows, Mud Flows.
- Floods – Inundation, Erosion.
- Snow Avalanches.
- Sand Blasting (Windblown)
