Radioactive decay is called nuclear decay and is the process by which the unstable nucleus losses energy. The material that becomes unstable is known as radioactive. The common types in alpha, beta and gamma decay.
The rate of decay or the activity of the substance is characterized by the half-life. That is the time taken by the activity of the given amount of a radioactive substance to decay its initial values. Other quantities include decay constant and mean lifetime.Thus the option A is correct.

All elements have a half-life in radioactive decay. The correct option is A.
Some unstable isotopes go through radioactive decay as a natural process to become more stable. When radioactive decay occurs, the nucleus of an atom emits particles or radiation on its own, changing the original element into a different one. This process takes place in elements whose isotopes have unstable atomic nuclei.
A radioactive isotope's half-life is the amount of time it takes for half of its radioactive atoms to decay in a sample. Radioactive decay can happen to any element that has isotopes with a half-life. Because not all elements have radioactive isotopes, not all elements experience radioactive decay, which is a crucial distinction to make. Only a few particular isotopes of some elements are radioactive.
Thus, the ideal selection is option A,

Explain Pangaea, Pannotia, Laurasia, Gondwana, and any other supercontinents that have been theorized.
In geology, a supercontinent is the assembly of most or all of Earth's continental blocks or cratons to form a single large landmass.However, some earth scientists use a different definition: "a grouping of formerly dispersed continents", which leaves room for interpretation and is easier to apply to Precambrian times although a minimum of about 75% of the continental crust then in existence has been proposed as a limit to separate supercontinents from other groupings.
Supercontinents have assembled and dispersed multiple times in the geologic past According to the modern definitions, a supercontinent does not exist today. The supercontinent Pangaea is the collective name describing all of the continental landmasses when they were most recently near to one another. The positions of continents have been accurately determined back to the early Jurassic, shortly before the breakup of Pangaea The earlier continent Gondwana is not considered a supercontinent under the first definition, since the landmasses of Baltica, Laurentia and Siberia were separate at the time.

Explanation:
coals occur in seams. why?
Explanation:
Coal seams are formed from dead and decaying organic matter. Generally, this matter came from ancient peat bogs that died and fell into shallow, stagnant waters. As this material decayed, it became peat over time. As this peat was buried under sediment, the temperature increased and the pressure became greater.
Coal seams originate and are formed by the consolidation of biota, minerals, and natural chemicals through geologic time. Compression, heat, sedimentation, erosion, and chemical energy are agents of the coal formation process.

The fishing industry of Maldives was destroyed in 2004 because of the tsunami. Hence, Option C is correct.
What is a tsunami?The Japanese term for the wave is "nami," while the word "tsu" means harbor. Tsunamis are waves brought on by the abrupt movement of the ocean's surface as a result of aftershocks, underwater landslides, landfalls into the water, powerful eruptions, or meteorite impacts.
The earliest tsunami ever observed happened in 479 BC. A Persian army that was advancing on the Greek town of Potidaea was wiped out. In his work Chronicle of the Peloponnesian War (3.89.1-6), the Greek historian Herodotus questioned the causes of tsunamis as early as 426 BC.
In 2004, this ranks one of the ten worst earthquakes and the worst tsunami in the recorded track record when it comes to the number of lives killed.
Thus, Option C is correct.
