movements of the earth

The Earth moves in two significant ways: rotation and revolution. These movements have profound impacts on life on Earth, including climate, weather patterns, and the perception of time.

1. Rotation: This refers to the spinning of the Earth on its axis. An axis is an imaginary line that runs through the Earth from the North Pole to the South Pole. The Earth completes one rotation every 24 hours, which we perceive as a day. The rotation of the Earth causes day and night; when a particular area faces the Sun, it experiences daylight, and when it faces away, it's night.

2. Revolution: This is the movement of the Earth around the Sun in an elliptical (oval-shaped) orbit. The Earth takes approximately 365.25 days to complete one revolution, which is why we have a leap year every four years to account for the extra quarter day. The Earth's revolution around the Sun, coupled with its tilted axis (at an angle of about 23.5 degrees), causes the changing seasons.

Aside from these, there are also slower movements happening beneath the Earth's surface. These are tectonic movements, resulting from the motion of the Earth's lithospheric plates. This movement causes natural events like earthquakes, volcanic eruptions, and the creation of mountain ranges, but these changes occur over hundreds to millions of years.

Embark on an exploratory journey through the transformative processes of Our Changing Earth with Class 7th Geography Chapter 3. This chapter uncovers the perpetual transformations that our Earth undergoes, shaping its landscapes and creating awe-inspiring geographical features.

In the fascinating world of Geography Class 7 Chapter 3, students get to learn about the processes that lead to the formation of landforms such as beaches. Curious how beaches are formed class 7th? Beaches form through the accumulation of sand and other sediment deposited by the action of waves along the coastline.

Understanding what is erosion class 7 is another crucial part of this chapter. Erosion is a process where rocks, soil, and other surface material are worn away and moved to another location by natural agents such as wind, water, or ice. This process significantly contributes to the ever-changing face of our Earth.

The chapter also reveals the forces behind the moving of Earth's lithospheric plates. Students often wonder why do the plates move class 7. The Earth's lithospheric plates move due to the convective movements in the semi-fluid mantle beneath them, leading to phenomena like earthquakes and volcanic eruptions.

Not just the explanations, we also offer Class 7 Geography Chapter 3 question answer to help students test their understanding of the chapter, and prepare for examinations.
