The document is about water and rocks in a 4th grade social science unit. It includes a mind map showing the water cycle and where water is found on Earth, such as oceans, seas, rivers, lakes, glaciers, and aquifers. It also discusses the geosphere, explaining that rocks are made up of minerals and can be classified as igneous, metamorphic, or sedimentary based on how they are formed. Additionally, it covers tectonic plates and the factors involved in forming Earth's relief, such as coastal, oceanic, and inland landforms.

11. THE GEOSPHERE

12. A mineral is a solid, inorganic substance formed
in nature. Minerals have different properties:

13. Rocks are groups of minerals. They can be
Classified acoording to the way they are formed.
Igneous rocks are formed when magma comes up to the surface,
cools down and solidifies.
Metamorphic rocks are formed by heat
and pressure of rocks on other rocks
Sedementary rocks are formed
by the erosion of other rocks

14. THE FORMATION OF THE RELIEF
Earth’s crust is divided up like a jigsaw puzzle with huge pieces: tectonic plates.
The tectonic plates have been moving since Earth’s crust was formed 4 millions
years ago.
