(i) How are fold mountains formed?
(ii) Give an example of a young fold mountain.
(i) What are Fossils? In which type of rocks do we find fossils?
(ii) What do you understand by 'ROCK CYCLE'?
Answers
Answer:
(i Fold mountains are formed when two plates move together (a compressional plate margin). This can be where two continental plates move towards each other or a continental and an oceanic plate. The movement of the two plates forces sedimentary rocks upwards into a series of folds.
(ii) The Himalayas, the Andes and the Rockies mountains are some examples of young fold mountains.
(iii) A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants.
Fossils, the preserved remains of animal and plant life, are mostly found embedded in sedimentary rocks. Of the sedimentary rocks, most fossils occur in shale, limestone and sandstone. Earth contains three types of rocks: metamorphic, igneous and sedimentary.
(iv) The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions.

Answer:
1. fold mountain were formed when two plates moves together towards each other
2.himalya and andies
3.the dead decaying plant and animals are buried under ground these are convert into fossil. sedimentary rock
4.it is a process in which one type of rock convert into other type
