Volcanoes
Are all volcanoes erupting all the time?
No
What is a mineral?
A naturally occurring, inorganic solid that has a specific chemical composition and a crystal structure.
What are the three major types of rocks?
Igneous, metamorphic, and sedimentary.
what is Compaction?
the exertion of force on something so that it becomes more dense.
What is the process that turns rocks into sediment
Weathering and erosion.
What is a volcano?
A volcano is an opening on the surface of a planet or moon that allows hot material, such as molten rock, ash, and gas, to escape from inside the planet.
How are solid minerals formed?
When molten rock cools and crystallizes, it forms minerals. Slow cooling results in larger crystals, while rapid cooling forms smaller ones.
True or False
an igneous rock can not become a sedimentary rock?
False
How many years does Granite last?
100
What are the three main agents of erosion?
Water, wind, and ice.
Why do volcanoes erupt?
Volcanoes erupt because of pressure from gases in the magma. As the gas bubbles expand, they increase the pressure until the magma is forced out of a weak spot in the Earth's crust.
What are the five characteristics of a mineral?
What is one example of a sedimentary rock
Examples include limestone, sandstone, or shale
what is stratification in geology ?
the layering of rock, particularly in sedimentary and some volcanic rocks, where distinct strata or layers form over time from the deposition of sediments or lava flows
What are fossils?
Fossils are the preserved remains or traces of ancient organisms and are most often found in sedimentary rocks.
How are volcanoes formed?
Volcanoes often form a mountain or hill as layers of rock and ash build up from repeated eruptions.
What is common mineral properties used for identification?
Luster ,Color ,Hardness ,Cleavage ,or Fracture
(if you said any of these your correct)
How is an igneous rock formed?
When molten rock (magma or lava) cools and solidifies.
What happens to the air in the soil when it is compacted?
The air is pushed out of the soil as the particles are pushed closer together.
True or False
Stratification offers a record of past geological and environmental conditions
true
Is it possible for volcanoes to produce lightning, and if so, how?
Yes, volcanic lightning can occur.
Which mineral has a hardness of 7 on the Mohs hardness scale and is known for its piezoelectric properties?
Quartz.
Which rock type is not igneous?
Limestone, Obsidian, basalt, or granite
Limestone
How does compaction affect a soil's structure?
Compaction brings soil particles closer together, reducing pore space. This leads to a denser, more ordered structure.
What are the main factors that drive the rock cycle?
Factors include water, accelerated erosion, plate tectonics, continental collision, subduction zones, and spreading ridges.
