The air parcel above has a temperature of 30 deg C on the surface. Its Dew Point temperature is 20 deg C. The dry adiabatic lapse rate is 10 deg C/km and the moist adiabatic lapse rate is 6 deg C/km. An external force lifts the air parcel from the surface to 1 km of altitude. At 1 km the external forcing is removed. What will happen to the air parcel once the external forcing is removed? Will a cloud form?

Once the external force is removed , the air parcel will remain at that level.

Yes a cloud will form

Explanation:

Given that:

Temperature of the air parcel = 30 ° C

Dew point temperature = 20 ° C

Dry adiabatic lapse rate D = 10° C/Km

Moist adiabatic lapse rate M= 4° C/Km

external force lifting the air parcel from surface to the attitude = 1 km

Let first calculate the air temperature T at the top of the mountain

T =

T = 30 ° C - (  10 ° C/Km × 1 km ) - ( 4° C/Km × 1 km )

T =  30 ° C -  10 ° C -  4 ° C

T =  30 ° C - 14 ° C

T =  16  ° C

The temperature at the top of the mountain is 16  ° C

What will happen to the air parcel once the external forcing is removed?

Once the external force is removed , the air parcel will remain at that level.

This is because, from the information given:  air temperature will drop to .20° C by the dry adiabatic lapse rate of 10° C/km at an altitude of 1 km.

Since both the air parcel temperature and the external temperature are taking place at 1 km ; then no external force is applied thus, they will remain at that level.

Will a cloud form?

Yes, a cloud will form

GIven that ; the Dew point temperature = 20 ° C , the air parcel will no be  able to either sink or rise. Therefore condensation of  vapor to water will occur which in turns form a cloud.

the wrong statement is - c. a desert had more biodiversity than a marsh.

the deserts are one of the places of the planet where there's the least biodiversity. the reasons for that are the climate and the lack of food sources, which hampers both the number of the species that can survive in it, and the number of the individuals in the species itself.

the marshes, on the other hand, are places where there's perfect conditions for lots of organisms to thrive. the temperature is moderate and nice, the amount of water and the food sources are on a high level, so there's an abundance of both plant and animal life in them.
