Assume a warm air bubble (or parcel) near Earth's surface, which has a temperature of 21°C within it, begins to rise upward. Assume it becomes saturated at 1000 m altitude, and due to unstable conditions it continues to rise to 2000 m altitude. What would the approximate temperature be inside the bubble, or parcel, of air at 2000 m ? (Assume a wet/moist lapse rate of 6 C/km.)

A. 6°C (42.5°F)
B. 7°C (44.6°F)
C. 8°C (46.4°F)
D. 9°C (48.2°F)
E. 5°C (41.°F)

When a rock is mechanically weathered, the surface area of the rock is increased, which allows a greater amount of chemical weathering to occur. the surface area of the rock is increased, which hinders chemical weathering. the volume of the rock is decreased, which hinders chemical weathering. the volume of the rock is increased, which allows a greater amount of chemical weathering to occur. the surface area of the rock is decreased, which allows a greater amount of chemical weathering to occur
