Both statements describe standard facts about how air temperature is measured and how it changes with height.

Lithification is the name for turning loose sediment into solid rock. Fragments produced by weathering and erosion are carried by rivers, wind, glaciers or waves and laid down in layers.

Pressure of water breaks rock mechanically without changing its minerals, so it is a physical process. Weathering is the breaking down of rocks where they lie.

These are four of the twelve soil orders in the USDA Soil Taxonomy, the classification also used by Indian soil scientists.

By weight, calcium is the smallest of the four and oxygen the largest, so the ascending order is calcium, aluminium, silicon, oxygen.

The divide between the two great northern systems does not run along a mountain here but across the almost flat plain of Haryana, and Ambala sits on it, so water falling a little to its west goes to the Ghaggar and the Indus side while water falling to its east…

It is the second of the two large west flowing peninsular rivers and runs almost parallel to the Narmada, with the Satpura range between them.

The correct answer is A, the Amarkantak plateau in Madhya Pradesh, where the Narmada rises at about one thousand metres and begins its westward journey of some thirteen hundred kilometres through Madhya Pradesh and Gujarat to the Gulf of Khambhat; on the way it makes the Dhuandhar falls and the…

It flows west through the narrow rift between the Vindhya and the Satpura ranges and opens into the Gulf of Khambhat, where strong tides sweep away the silt, so the river ends in a funnel shaped estuary and not a delta; the Tapi, which also flows west in a rift…

In a radial pattern the streams start from a dome, a volcanic cone or a high plateau and run outward in all directions like the spokes of a wheel.
