1. The world in spatial terms
The purpose of the first essential element of geography is to study the relationships between people, places, and environments by mapping information about them into a spatial context.
2. Places and regions
The purpose of the second essential element of geography is to show how identities and lives of individuals and peoples are rooted in particular places and in those human constructs called regions
3. Physical systems
The purpose of the third essential element of geography is to identify how physical processes shape the Earth’s surface and how they interact with plant and animal life to create, sustain, and modify ecosystems.
4. Human systems
The purpose of the fourth essential element of geography is to show how people are central to geography in that human activities help shape the Earth’s surface, human settlements and structures.
5. Environment and society
The purpose of the fifth essential element of geography is to show how the the physical environment is modified by human activities, largely as a consequence of the ways in which human societies value and use Earth’s natural resources.
6. The uses of geography
The purpose of the sixth essential element of geography is to show how the knowledge of geography enables people to develop an understanding of the relationships between people, places, and environments over time -- that is, of Earth as it was, is, and might be.
Answer:
Option (2)
Explanation:
The earth's interior is divided into 3 parts which includes the crust, core and the mantle. The core of the earth represents the extreme interior part of the earth which is covered by the mantle. The density of the core is the highest and is approximately 13 g/cm³, Whereas, the density of the mantle (including both the upper and lower mantle) is relatively less and is about 4.5 g/cm³ on an average.
The asthenosphere is the layer in which the rocks are solid but they tends to flow during deformation. This layer is present in the apex portion of the upper mantle and it has a density of nearly 3.3g/cm³.
The continental and the oceanic crust represents the outermost portion of the earth. The rocks of oceanic crust are denser than the rocks of continental crust. The density of the oceanic crust is nearly 3 g/cm³ and continental crust is 2.7g/cm³.
Thus, the continental crust is the less dense, compared to the other layers of the earth.
Hence, the correct answer is option (2).
