Folds and faults are difficult to identify because they occur in the interior of rocks and also due to the dense nature of the materials.
<h3>What are faults and folds?</h3>
Faults are lines of weakness are present in materials dues to uneven positioning of the particles of the material.
Folds occurs when infolds occur in materials.
Faults and folds usually occur in rocks.
Folds and faults are difficult to identify because they occur internally and also due to the dense nature of the materials.

Answer:
The star's luminosity rises above its previous level. Because it is so cool, the surface will be red, and it will be much farther away from the center than it was during the earlier stages of star evolution. Despite its lower surface temperature, the red giant has a large surface area, which makes it very luminous.
Answer with Explanation:
We are given that
Power of toaster=
Power of electric frying pan=
Power of lamp=
Current in circuit=15 A
Potential difference= V=120 V
We know that
Current=
Using the formula
Current drawn by toaster=
Current drawn by electric frying pan=
Current drawn by lamp=
Statement 1: 0 K = -273 °C. This is true. This has come to be referred to as absolute zero which is very theoretical as it has never been attained.
Statement 2: °C is not used with Kelvin scale. This is true. Kelvin is a scale equivalent to °C and thus ° is not used with Kelvin scale and this would be a different scale all together which does not exist.
Statement 3: Cryogenics has been defined as the production and characteristics of materials at very low temperatures. Therefore, it can also be defined as a study and thus this statement is true.
Statement 4: Volume of gas at absolute zero is, theoretically, thought to be zero. This is due to the reasoning that at that temperature, all the gas will have condensed to liquid. However, absolute zero temperature has never been attained. Therefore, this statement is theoretically true.
Statement 5: Scientist have not yet cooled anything to absolute zero and thus this statement is false.
