The total difference is 45 + 45 = 90 degrees. Therefore, the time difference is 90/15 = 6 hours.

The total difference in degrees is 60° + 30° = 90°. Therefore, the time difference is 90° / 15° = 6 hours.

The total difference in longitude is 75 + 15 = 90 degrees. Therefore, the time difference is 90/15 = 6 hours.

The difference in longitude is 75 - 45 = 30 degrees. 30/15 = 2 hours.

The time difference is calculated as (90° - 30°) / 15° = 4 hours. Therefore, the answer is 4 hours.

The total area of India is approximately 3.287 million square kilometers.

Using the wind chill formula, Wind Chill = 13.12 + 0.6215*T - 11.37*(V^0.16) + 0.3965*T*(V^0.16), we find it to be approximately -15°C.

A blizzard is characterized by a significant drop in temperature and heavy snowfall.

A tropical climate is characterized by high temperatures and heavy rainfall throughout the year.

China has the largest area of arable land, followed closely by India and the United States.

The Thar Desert is located in India, primarily in the state of Rajasthan.

Bangalore is known as the 'Silicon Valley of India' due to its IT industry.

Punjab is known as the 'Land of Five Rivers' due to the five major rivers that flow through it.

Assam is the largest producer of tea in India.

The Ganges is considered the longest river in India, flowing over 2,500 kilometers.

Goa is the smallest state in India by area, covering approximately 3,702 square kilometers.

The layer directly beneath the Earth's crust is the mantle.

The Outer Core is the only layer of the Earth that is in a liquid state.

The Outer Core is primarily composed of molten iron and nickel, which is responsible for Earth's magnetic field.

The Mantle is primarily composed of molten rock and is located between the crust and the outer core.

The movement of liquid iron in the Outer Core generates the Earth's magnetic field.

The Earth's crust is where tectonic activity occurs, as it is divided into tectonic plates.

The Mantle, particularly the asthenosphere, is responsible for the movement of tectonic plates.

The movement of molten iron in the outer core generates the Earth's magnetic field.

The mantle is responsible for volcanic activity as it contains magma that can rise to the surface through the crust.

The Inner Core is solid and composed mainly of iron and nickel, despite the high temperatures.

The crust is the outermost layer of the Earth and is solid, composed mainly of silicate rocks.

The inner core is solid due to the immense pressure, despite its high temperature.

The mantle is solid but can flow slowly over geological time, behaving like a viscous fluid.

The Mantle is the thickest layer of the Earth, extending about 2900 km below the crust.
