Answer 1

Question

Chapter 5, Problem 1QQ

To determine

The source which continues to contribute to Earth's internal heat.

Expert Solution & Answer

Answer to Problem 1QQ

Option (b). Radioactive decay

Explanation of Solution

Accretion on Earth occurs in the early stages. Planetesimal bombardment is deposited due to gravity toward the core of the Earth. Gravity has a major role in accretion where gravitational potential energy is converted into thermal energy. Accretion cannot be the continuous heat source of internal energy.

Thus, option (a) is incorrect.

The sunlight falls on the Earth, heats the land, ocean, and atmosphere but does not reach and warms the interior. Heated rocks in the Earth's crust act as an insulator and prevent the heat transfer from outside towards the inner side. Sunlight cannot be the continuous heat source of internal energy.

Thus, option (c) is incorrect.

Radioactive decay in Earth's mantle convert parent element decay into daughter isotopes and release heat. This released heat flows from the interior to the surface of the Earth slowly and continuously through conduction. The radioactive process is the continuous heat source of internal energy.

Thus, option (b) is correct.

Students have asked these similar questions

In (Figure 1) C1 = 6.00 μF, C2 = 6.00 μF, C3 = 12.0 μF, and C4 = 3.00 μF. The capacitor network is connected to an applied potential difference Vab. After the charges on the capacitors have reached their final values, the voltage across C3 is 40.0 V. What is the voltage across C4? What is the voltage Vab applied to the network? Please explain everything in steps.

I need help with these questions again. A step by step working out with diagrams that explains more clearly

In a certain region of space the electric potential is given by V=+Ax2y−Bxy2, where A = 5.00 V/m3 and B = 8.00 V/m3. Calculate the direction angle of the electric field at the point in the region that has cordinates x = 2.50 m, y = 0.400 m, and z = 0. Please explain. The answer is not 60, 120, or 30.
