What do we call, natural aggregates made up of one or more minerals. They form, with minerals, the geosphere of our planet
What is a rock?
100
The type of rock formed from molten rocks from the mantle. These types of rocks form from the solidification of magma. They are also called magmatic rocks.
What is igneous rocks.
100
What are rocks that are formed of different fragments of previous rocks or due to the accumulation of chemical substances or remains of living things called?
What are Sedimentary rocks?
100
What rock is the result of a transformation of a pre-existing rock. The original rock is subjected to very high heat and pressure, usually formed in the crust of the Earth that cause obvious physical and/or chemical changes. Examples of these rock types include marble, slate, gneiss, schist.
What are Metamorphic rocks?
100
A fossil is the remains of an organism from the past, or remains of its activity. Nearly all fossils have been preserved in what type of rock.
What is sedimentary rock?
100
Name two fossil fuels made from the remains of organisms that lived millions of years ago that burn easily and are used to generate energy.
What are coal and petroleum.
200
Geologists classify rocks into three different groups. What are the names of the three different types of rocks?
What is igneous rock, sedimentary rock, and metamorphic rock?
200
Name three regions in Spain where Igneous rock is found.
Olot: in Girona.
Calatrava´s region: in Ciudad Real.
Gata´s cape in Murcia.
Canary islands.
200
What do we call the broken pieces of older Sedimentary rocks?
What are clasts?
200
Foliated rock is a type of metamorphic rock that has distinct, repetitive layers.
Give at least one example of this type of rock.
What is (Slate, Schist or gneiss?)
200
What do fossils tell us about life? Name two things that we can learn from fossils.
What are organisms that lived in the past, what organisms were like, what was the habitat of the organism, what was the behavior of the organism.
200
Name two ways that coal and petroleum provide us with energy.
• obtaining energy in industry.
• for heating our houses.
• for moving our vehicles.
300
Name two ways to tell the differences between rocks.
Their composition = what they are made of
Their origin = where they come from
Their texture = how they feel, look, size, layers and distribution of grains and crystals.
Their age = fossils
300
What do we call Igneous rocks where magma solidifies at high depths, inside of the crust. As it solidifies slowly, crystals have long periods of time to grow and are visible at sight. Examples of this are granite or gabbro.
What is Plutonic rocks?
300
What type of Sedimentary rocks are formed as a result of the precipitation of chemical substances such as calcium carbonate forming limestones.
What are Chemical rocks?
300
Metamorphic Rocks can be classified into two different groups. What are the names?
What are Foliated and Non-Foliated rocks?
300
How does the fossilisation process usually occur?
What is .....
300
Name the process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere.
What is the greenhouse effect?
400
What do we call a rock that is formed from just one mineral or a uniform paste of just one colour?
What is homogeneous rock.
400
This type of volcanic igneous rock is black with a glassy texture. When broken it creates a very sharped curved surface.
What is Obsidian?
400
What rocks are formed due to the accumulation of remains of living things such as shells (limestone with shells) or coal (with remains of plants).
What are Organic rocks?
400
What do we call metamorphic rocks that have their minerals formed in layers?
What are foliated metamorphic rocks?
400
What do we call rocks made up of sand, gravels, and powdered rocks that are used a lot in construction, roads, and train tracks.
What are aggregates.
400
Nitrogen and sulphur acid both create what that is causing problems in the environment and health of people.
What is acid rain?
500
Name a rock where the grains of crystal are visible in the rock.
granite
500
Name a rock that has a vesicular texture
Basalt or pumice
500
Give two examples of conglomerate sedimentary rocks.
Limestone, sandstone or quartz
500
Give two examples of foliated metamorphic rocks.
What are Slate, Schist or gneiss.
500
Name an agglomerate used for joining materials together in construction.
What is cement or lime.
500
What is the name of coal that comes from the transformation of hard coal. It is the best of all types of coal with a carbon content of up to 95%. It is the least polluting (it gives off little smoke) and has the highest calorific value. It is black, shiny and very hard (difficult to scratch). Its main use today is to produce coke. It requires hundred million years to be formed.
What is Anthracite coal?
600
What do we call sedimentary rocks consisting of pebbles or other pieces of rock, surrounded by a finer cementing material.
What are conglomerates?
600
Name the three types of classification of Igneous rocks.
What is plutonic, volcanic, and intermediate rocks.
600
Name the three different types of sedimentary rocks.
• Clastic rocks.
• Chemical rocks.
• Organic rocks.
600
Define non-foliated rocks and give an example of a non-foliated rock.
What are metamorphic rocks that do not form in layers and instead the minerals grow in size thanks to the higher temperatures. Examples are quartzite and marble.
600
Granite, sandstone, and basalt are examples of what type of rocks used to make sculptures or decorative objects. They are usually shiny and beautiful. Many famous monuments are made of this type of rock.
What are quarried rocks?
600
What is the name of coal that is formed when peat is compressed. It is black in colour and usually has a texture similar to that of the wood from which it comes. It has a carbon content of between 60% and 75%. It is a medium quality fuel. It is a coal formed a few million years ago. It is used as a fuel to generate electricity.
What is Lignite?
