two descriptions about physical quantities are given below: quantity a: it is unaffected by the location of an object in space. quantity b: it can be measured in kilograms. what quantities are these most likely describing? a.  both quantity a and quantity b are mass. b. both quantity a and quantity b are weight. c. quantity a is weight and quantity b is mass. d. quantity a is mass and quantity b is weight.

Option A, Both Quantity A and Quantity B are mass

Explanation:

Mass is the total amount of matter contained in an object or substance and it remains the same irrespective of any external factor such as gravity.

This means that an elephant which has a mass of 100 kg on earth has a mass of 100 kg on moon or any other planet.

Since mass can be measured in kilogram, option A is the most suitable answer.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
