Volume of water = Porosity × Volume of soil = 0.3 × 100 m³ = 30 m³.

Using the lapse rate of 6.5°C/km, the temperature drop at 3000 meters is 6.5 * 3 = 19.5°C. Therefore, the temperature at 3000 meters is 30°C - 19.5°C = 10.5°C.

Discharge = Velocity × Area. Area = Width × Depth. Assuming depth = 1 m, Area = 20 m × 1 m = 20 m². Discharge = 3 m/s × 20 m² = 60 m³/s.

Volume = width × depth × length = 200 m × 5 m × 1000 m = 1,000,000 m³.

The wind direction is named from where it originates, so it is blowing from the North.

The angular distance is calculated as |90° - 30°| = 60°.

The Earth rotates 360 degrees in 24 hours, so in 1 hour, it rotates 360/24 = 15 degrees.

The approximate area of India is 3.28 million square kilometers.

The circumference of the Earth at the equator is approximately 24000 km.

The temperature at the Earth's inner core is estimated to be around 5000°C to 6000°C.

The Earth's crust varies in thickness, averaging about 30-50 km under continents and about 5-10 km under oceans.

The average atmospheric pressure at sea level is defined as 1013.25 millibars.

The average density of the Earth is about 5.5 g/cm³, which is higher than the density of the crust.

The average temperature of the Earth is approximately 15°C.

The capital of India is New Delhi.

Kangchenjunga is the highest peak in India, standing at 8,586 meters.

45°E corresponds to 45 / 15 = 3 hours ahead of GMT, so it will be 12:00 noon + 3 hours = 3:00 PM.

90 degrees East is 6 hours ahead of GMT, so 6:00 AM + 6 hours = 12:00 PM.

The Earth's mantle is mainly composed of silicate minerals, which include olivine and pyroxene.

Latitude is the main factor that determines the climate of a region.

The main reason for the occurrence of seasons on Earth is the tilt of the Earth's axis, which affects the angle of sunlight received.

The primary cause of ocean currents is wind patterns, which drive the movement of water across the surface.

The Earth's crust is primarily composed of basalt (oceanic crust) and granite (continental crust).

Latitude is the primary factor that affects climate in a region, as it determines the angle of sunlight received.

All of the above factors affect soil erosion rate.

Seismic waves generated by earthquakes are the primary method used to study the Earth's interior structure.

The Earth's magnetic field is primarily generated by the flow of molten iron in the outer core.

The primary source of energy for the Earth's climate system is the Sun.

Climate refers to the average weather conditions in a particular area over a long period, typically 30 years or more.

The boundary between two different air masses is called a front.
