Answer (2)
This question covers topics related to Earth's layers and rocks. The correct answers are option (a) lithosphere, option (b) sedimentary rocks, option (a) crust, and option (c) sedimentary. The fill-in-the-blank responses include 'rock', 'crust', 'fossils', and 'marble', while the missing letters complete 'lithosphere', 'seismograph', and 'core'.

A. Darken the correct option in the OMR Sheet:
The Earth's layer which is made up of rocks is a) lithosphere
The lithosphere is the correct option because it refers to the rigid outer layer of the Earth, consisting of the crust and the upper mantle, which is primarily made of rocks.
Sandstone, clay, and shale are: b) sedimentary rocks
Sedimentary rocks are formed from particles or sediments like sand, clay, and other materials. Sandstone, clay, and shale are types of sedimentary rocks because they are typically formed through the accumulation and compaction of sediments.
The thinnest layer of the earth is: a) crust
The crust is the thinnest layer of the Earth. It makes up the Earth's outer shell and is much thinner compared to the mantle and core.
Which type of rocks contain fossils? c) sedimentary
Sedimentary rocks often contain fossils because they are formed on the Earth's surface at relatively low temperatures and pressures, where organisms live and die. The remains of these organisms can be trapped in sediments that eventually harden into rock.
B. Fill in the blanks:
'Lithos' in Greek means "stone" or "rock".
The uppermost layer of the Earth is known as the "crust".
The remains of plants and animals trapped within layers of rock are called "fossils".
The metamorphic rock "marble" is formed from limestone.
C. Fill in the missing letters with the help of given clues:
The solid part of the Earth's crust is "lithosphere".
Earthquakes are measured by a "Seismograph".
The innermost part of the Earth is the "Core".
This detailed breakdown provides an understanding of Earth's structure and types of rocks, assisting in correctly answering the questions.
