Rotation is Earth's spinning on its axis, which takes approximately 24 hours and creates day and night. Revolution is Earth's orbital motion around the Sun, which takes about 365.25 days and creates the year. Option A has the definitions swapped. Option C incorrectly mentions spinning on the equator instead of the axis, and its description of revolution is nonsensical. Option D also swaps the correct definitions.

Earth's orbit is nearly circular with only about 3% variation in distance throughout the year - from 147 million km at perihelion to 152 million km at aphelion. This small change cannot explain seasonal temperature differences. Instead, Earth's 23.5-degree axial tilt means different parts of Earth receive varying solar intensity at different times of year. Option B is wrong - the orbital shape change is real, not an illusion. Option C is factually incorrect. Option D is illogical - timing correlation doesn't explain causation.

Ctrl+H in Excel opens the Find and Replace dialog box, allowing you to search for specific content and replace it with new content. Ctrl+X is Cut, and rows/columns are deleted with Delete key or right-click menu.

F7 in Excel launches the spell checker to review spelling and grammar errors in your worksheet. This shortcut is consistent across Microsoft Office applications. F6 moves between panes, and sheets are deleted differently.

Ctrl+Page Up is a keyboard shortcut in Excel that navigates to the previous worksheet tab. This is useful for quickly moving between multiple sheets in a workbook without using the mouse. Ctrl+Page Down would move to the next worksheet instead.

Ctrl+Insert is a standard keyboard shortcut for copying selected content in Excel and many other applications. It works identically to the more commonly known Ctrl+C shortcut. This shortcut copies the selected cells to the clipboard for pasting later.

Ctrl+Shift+; (semicolon) inserts the current time in Excel. The standard Ctrl+; inserts the current date, while Ctrl+Shift+: (which is the same as Ctrl+Shift+;) inserts the current time. Both are useful for timestamping data entries.

Lal Bahadur Shastri, India's second Prime Minister, was cremated at Vijay Ghat in Delhi. This memorial is one of several memorials along the Yamuna River, where other Indian leaders like Gandhi (Raj Ghat) and Nehru (Shantivan) are also memorialized. Vijay means victory, honoring his leadership during the 1965 war.

Ferdinand Magellan named the Pacific Ocean in 1520 during his circumnavigation expedition. He called it 'Mar Pacifico' meaning 'peaceful sea' because the waters seemed calm compared to the stormy seas he had just navigated near South America. The name reflects his first impression of the ocean's tranquility.

The Challenger Deep in the Mariana Trench is the deepest known point in the Pacific Ocean and the entire world. Located in the western Pacific, it reaches approximately 10,928 meters (35,853 feet) below sea level. The Puerto Rico Trench is in the Atlantic Ocean, while Tonga Trench is also in the Pacific but shallower.

The name 'Pacific Ocean' comes from the Latin word 'pacificus' meaning 'peaceful'. Ferdinand Magellan named it 'Mar Pacifico' (peaceful sea) in 1520 because the waters appeared calm compared to the stormy Drake Passage he had just navigated. The name reflects the ocean's tranquil appearance when first encountered by Europeans.

The Pacific Ocean is the deepest ocean in the world, with an average depth of about 4,280 meters and maximum depth of 10,928 meters at the Challenger Deep. It contains the deepest points on Earth, including the Mariana Trench. The other oceans listed (Indian, Atlantic, Arctic) are all shallower in comparison.

The Atlantic Ocean is named after Atlas from Greek mythology. The name comes from 'Atlantis' and refers to the Sea of Atlas. In Greek mythology, Atlas was a Titan who held up the sky, and the ocean was named in his honor. This naming tradition reflects how ancient cultures influenced geographical terminology.

The Atlantic Ocean has an S-shape when viewed on a map, created by the continental configurations of North and South America, Europe, and Africa. This distinctive shape results from plate tectonics and continental drift over millions of years. The S-curve is most prominent between South America and Africa.

The Puerto Rico Trench is the deepest point in the Atlantic Ocean, reaching approximately 8,605 meters (28,232 feet) deep. Located north of Puerto Rico between the Atlantic and Caribbean, it's the deepest part of the Atlantic. The Challenger Deep is in the Pacific, while Tonga and Yap Trenches are in the Pacific Ocean.

The Indian Ocean derives its name from India, making it the only ocean named after a country. The Atlantic is named after Atlas from Greek mythology, Pacific means 'peaceful' in Latin, and Antarctic refers to the Antarctic region.

The Antarctic Ocean is officially designated as the Southern Ocean, encircling Antarctica. It was recognized by the International Hydrographic Organization in 2000 as the fifth ocean.

The Arctic Ocean is the smallest and shallowest of the world's five oceans, covering approximately 14 million square kilometers. It surrounds the Arctic and is the only ocean located mostly within the Arctic Circle.

Gandhi's vision centered on rural self-sufficiency where villagers produced their own food and clothing, rejecting industrialization. This self-reliance in basic needs formed the foundation of his 'idyllic and rural paradise' concept.
