What is the process by which elements form?
In the stars, fusion mainly. On Earth, radioactive decay.

Can some help The foot of a mountian is a an elevation of 1000 meter ablove sea level. the temperture thire is 15C. If the Temperature at an elevation of 3000 meters is only 5C what is eviromental lapse rate?
To calculate the environmental lapse rate, you need to know the change in temperature as you move up in elevation. The formula for environmental lapse rate is:
Environmental Lapse Rate = (Temperature at higher elevation - Temperature at lower elevation) / (Elevation at higher point - Elevation at lower point)
In this case, the temperature at the foot of the mountain is 15°C (lower elevation) and the temperature at 3000 meters is 5°C (higher elevation). The elevation at the foot of the mountain is 1000 meters.
So, the environmental lapse rate can be calculated as follows:
Environmental Lapse Rate = (5°C - 15°C) / (3000m - 1000m)
Environmental Lapse Rate = -10°C / 2000m
Environmental Lapse Rate = -0.005°C/m
Therefore, the environmental lapse rate is approximately -0.005°C/m. This indicates that the temperature decreases by 0.005 degrees Celsius for every meter increase in elevation.
