Minerals
The three features of minerals.
What are natural substances, solid, and inorganic.
True or False: Rocks may contain parts of dead living things.
What is true?
Mining is the process of extracting these two materials from the ground.
What are minerals and rocks?
Earthquakes, Volcanoes, and the formation of mountain ranges are examples of this.
What are internal geological processes?
True or False: Humans cannot be classified as geological agents.
What is false?
The physical property used to identify Magnetite.
What is magnetism?
These are rocks that are formed when magma or lava cools down and solidifies.
What are igneous rocks?
This type of mining is used to extract minerals or rocks that are found deep in the ground.
What is underground mining?
This is the result of the action of internal and external geological processes.
What is the Earth's releif?
These can change the Earth's releif created by internal processes.
What are external geological agents?
Minerals can be classified as these, according to their chemical composition.
What are Silicates and Non-Silicates
These rocks have been changed after they were subjected to great heat, pressure, or both.
What are Metamorphic rocks?
Rocks and minerals cannot be easily replaced because they take millions of years to form, meaning they are this type of resource.
What is a non-renewable resource?
This external geological process is responsible for forming arches, sea caves, and meanders.
What is erosion?
These are a sudden shake of the ground due to the release of the Earth's internal energy.
What are earthquakes?
This classification of minerals does not contain silicon and oxygen.
What are Non-Silicates
This sedimentary rock is made up of rounded fragments cemented together.
What are conglomerates?
Using electric machinery, recycling waste, closing mines, and regeerating the area after mining stops are an example of this.
What is sustainability?
This occurs due to the deposition of materials transported by rivers when they reach the sea.
What are deltas?
These internal geological processes can be found on land and beneath the sea.
What are volcanoes?
This silicate mineral is used in the production of glass and ceramic tiles.
What is Feldspar?
These two rocks are used in construction.
What are Granite and Slate?
This is the biggest gold mine of the Roman Empire.
What is Las Medulas?
This example of the external geological agent, transportation, is sand or dust from the Sahara that is transported by the wind.
What is Calima?
This formation occured after the eruption of the Cumbre Vieja volcano, on the Canary Island of Palma.
What is a lava delta or fajana?
