Due to global warming, the polar ice caps and mountain glaciers would melt and the amount of water in the ocean would increase. It leads to a rise in the sea level and the melting of glaciers and sea-ice due to warming.
Effects of Global Warming are:

Sea level will rise 48 cm by the end of the twenty-first century.
Increase the incidence of annual flooding.
Insect-borne diseases like malaria, and leads to shifting in climatic boundaries, making some regions wetter and other dries.
The agricultural pattern would shift and the human population, as well as the ecosystem, would experience change.
Peninsular India would be submerged.
Global warming refers to the increase in average ground temperatures on earth. These higher temperatures across the planet are caused by an intensification of the greenhouse effect.

Preeti Dabral 1 year, 11 months ago

Gravitational waves stretch and squeeze the fabric of space and time on very minuscule scales; visually exaggerating these effects reveals how Earth is squeezed and stretched. Gravitational waves are generated when massive objects, such as pairs of black holes, accelerate through space and time.

Adrija Saha 1 year, 11 months ago

The knowledge about interior of the earth is obtained through direct sources and indirect sources. Direct sources include rock materials from mining areas and molten magma from volcanic eruptions. Besides, scientists are working on “Deep Ocean drilling Project” and “Integrated Ocean Drilling Project”. There are two sources for information about interior of the earth - a) Direct Sources and b) Indirect Sources: Direct Sources: Mining, drilling and volcanic eruption are examples of direct sources. During the process of mining and drilling rocks and minerals are extracted which gives information that there are layer system in the crust. Crust is made of many kinds of rocks and minerals. Volcanic eruption suggests that there is some zone inside the earth which is very hot and in liquid condition. Direct sources are not very reliable because mining and drilling can be done only up to some depth only. Indirect Sources: Seismic waves, gravitational field, magnetic field, falling meteors etc are example of indirect sources. They are very important for know about earth’s interior. Movement of seismic wave suggests that there are three layers in the earth and each layer has different density. Density increases toward the center of the earth. Movement of seismic wave suggests two things: a) There are three layers in the earth and b) Each layer has different density which increases toward the center of the earth.

(i) Geomorphology: It i is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near the Earth's surface.

(ii) Climatology:It is the branch of the atmospheric sciences concerned with both the description of climate and the analysis of the causes of climatic differences and changes and their practical consequences.

(iii) Hydrology: Hydrology is the scientific study of the movement, distribution, and quality of water on Earth and other planets, including the water cycle, water resources and environmental watershed sustainability.

(iv) Soil Geography: It is a branch of soil science that studies the pattern of distribution of soils on the earth's surface for the purpose of soil-geographic regionalization.

It is concerned with the study of the processes of soil formation, soil types, their fertility status, distribution and use.

The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose. In the inner solar system temperatures were as high as 2000 K, while in the outer solar system it was as cool as 50 K.

Preeti Dabral 2 years, 3 months ago

A cartographer, or map-maker creates a visual hierarchy when he or she decides how features appear on a map to illustrate data. Map making can be both subjective or objective-but its goal is always the visualizing of data with some spatial dimension. GIS is a model of such data in a computer environment.

A Geographic Information System (GIS) is a computer system that analyzes and displays geographically referenced information. It uses data that is attached to a unique location.

Pedagogy, most commonly understood as the approach to teaching, is the theory and practice of learning, and how this process influences, and is influenced by, the social, political and psychological development of learners
