Answer:
1.The Washington Monument is 555 feet tall.A.If 1 meter = 3.28 feet, what is the height of the Washington Monument in meters? 1,820.4 mB.A worker assigned to the restoration of the Washington Monument is checking the condition of the stone at the very top of the monument. A nickel with a mass of 0.005 kg is in her shirt pocket. What is the gravitational potential energy (GPE) of the nickel at the top of the monument?GPE = mghGPE = (0.005 kg)(0 m/s2)(1,820.4 m)GPE = 0 JC.What is the kinetic energy (KE) of the nickel in her shirt pocket at the top of the monument?KE = 1/2mv2KE = (0.5)(0.005 kg)(0 m/s)2KE = 0 JD.If the nickel accidentally falls out of her pocket, what will happen to the gravitational potential energy (GPE) of the nickel as it falls to the ground?The GPE will decrease because the height is decreasing.E.If the nickel accidentally falls out of her pocket, what will happen to the kinetic energy (KE) of the nickel as it falls to the ground

Answer:
The energy that drives this movement is heat within the earth, this heat comes from two main sources which are;
1) residual heat left over from the formation of our planet billions of years ago.
2) The radioactive decay of naturally occurring chemical elements (notably uranium, thorium, and potassium ) in the earth releases energy in the form of heat. These two sources of heat warm Earth’s mantle and cause it to rise and sink, this rising and sinking creates a convectional movement of earth mantle.
One characteristic of a sample of matter that indicates it is a pure
substance is the homogeneity of the molecular structure. If the structure is
the same all throughout such as liquid water, it is said to be homogenous.
