Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Cenozoic expansion of the climatic and geographic range of grasslands at the expense of woodlands is revealed by recent studies. The evidence of Cenozoic expansion of grassland and climatic cooling conditions are present in paleosols, fossils, and their stable isotopic compositions. Grasslands and their soils can be considered sinks for atmospheric CO2, CH4, and water vapor, and their Cenozoic evolution a contribution to long‐term global climatic cooling. Grassland soils are richer in organic matter than are woodland and desert soils of comparable climates, and when eroded, their crumb clods form sediment unusually rich in organic matter.
