Resources
Two types of Igneous rocks
volcanic and plutonic
THREE resources from the Geosphere
Minerals, Rocks and Soil
One resource from the Hydrosphere
Water
The crystals in its minerals are visible in _______________ rocks
Plutonic rocks
A layer of air that envelops our planet
Atmosphere
All the living beings on the planet.
Biosphere
This is the ball of rock and metal that remains if we remove all the other layers.
Geosphere
The water in and on the Earth’s crust.
Hydrosphere
The Earth has 4 concentric layers that provide different resources:
biosphere, atmosphere, hydrosphere and geosphere.
These are rocks formed by the solidification of magma
Igneous rocks
THREE resources from the Atmosphere
Oxygen, Carbon dioxide and Wind
These form when the lava from volcanoes cools and solidifies very quickly on the Earth’s surface.
Volcanic rocks
These rocks form when the heat and internal forces of the Earth produce changes in existing rocks
Metamorphic rocks
These form when magma solidifies slowly inside the crust.
Plutonic rocks
Their crystals are microscopic in ________________ rocks.
Volcanic rocks
Limestone, sandstone and mudstone, or clay, are ____________________ rocks.
Sedimentary rocks.
The rocks in the crust can break into fragments through the action of the air, water and changes in temperature in _____________________ rocks
Sedimentary rocks
Granite, Mudstone (clay) o Limestone are used in ______________

Recover materials made with geosphere resources to use them again is an example of _______________
Recycle
Find new uses for geosphere resources and the objects made with them is an example of ____________
Reuse
Marble, quartzite and slate are example of ____________________ rocks.
metamorphic rocks
Two examples of negative effects on the natural environment
