Rocks, minerals, and types of rocks and landmass

2. The lithosphere is solid because
it is made of rocks. Rocks may
be composed of a single mineral
or a group of minerals.

3. Petrology is the science that deals
with the study of the formation,
compositon, and classification of
rocks.

9. Molten materials that welled
up or flow onto the surface
are called lava.

10. SOME EXAMPLES
OF IGNEOUS ROCKS

11. GRANITE
RHYOLITE

12. SCORIA
ANDESITE

13. OBSIDIAN
GABBRO

14. BASALT

15. Sedimentary rocks are formed from small
particles of rocks that have been lithified
(compacted and cemented) together.

16. Weathering is the physical and
chemical breakdown of rocks.
Rocks are exposed to natural
processes like weathering and
erosion.

20. Metamorphic rocks are rocks that
chemically changed in form,
structure, and composition under
great heat and pressure and through
other agents of metamorphism.

22. ROCK TYPE METAMORPHIC ROCK

23. Minerals are naturally formed
elements and inorganic compounds
whose atoms and molecules are
bound together in a definite orderly
arrangement to form crystals

24. LANDFORMS

25. Continents are large areas of land. There are seven
continents in the world:
1. Africa
2. Asia
3. Europe
4. North America
5. South America
6. Austrilia
7. Antarctica

26. In terms of size, Asia is the
biggest continent.

27. Volcano
A volcano is a rupture in the crust of a planetary-
mass object, such as Earth, that allows hot lava,
volcanic ash, and gases to escape from a magma
chamber below the surface.

29. A plain is a broad area of
relatively flat land. Plains are one
of the major landforms, or types
of land, on Earth.

31. Some flatlands located
between mountains are called
valleys.

33. Flatlands located in high level
areas are called plateaus
