Which of the following best describes parent rock?
a)crushed gravel added to depleted soil to provide nutrients

b)the lowest layer of the soil horizon, containing little or no organic matter

c)high-nutrient igneous rock like obsidian, extruded from the earth’s magma

d)the primary stone sheet from which a boulder or stone originated

where's the following? you gotta add it to know what the choices are

explanation:

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:
