Answer: a) A landmass
Explanation:
A continent is composed of several huge land masses, a characteristic that differentiates it from the islands or peninsulas.
It should be noted that the sum of the total areas of the Earth's continents is about 148 million square kilometers of land. In addition, the continents constitute most (but not all) of the Earth's land surface.
A substantial rise in sea level along a coast during a severe storm is called a storm surge
<h3>
What is storm surge?</h3>
- A coastal flood or tsunami-like event of rising water known as a storm surge, storm flood, tidal surge, or storm tide is frequently linked to low-pressure weather systems like cyclones.
- It excludes waves and is calculated as the increase in water level above the typical tidal level.
- The high-speed wind pushing water towards the coast over a long fetch is the primary meteorological component causing a storm surge.
- The shallowness and orientation of the water body in the storm's path, the timing of tides, and the storm's impact on atmospheric pressure are other variables that affect how severe a storm surge will be. There is evidence to suggest that storm surge danger may be rising due to climate change.

Answer:
old crust is recycled by subduction
Explanation:
Answer:
No, <u>Hardy Weinberg Equilibrium is a theory that states the allele and genotype frequencies in a population will remain constant irrespective of the sexs.</u>
Explanation:
- Derivations from the HWE Hardy Weinberg Equilibrium assume that organisms are diploid, population size is infinite, and mating is random.
- In all the equilibrium the four fundamental factors like the selection, mutation, random mating including interbreeding and small population size. So, if the number of heterozygotes is 34 then the significant level is 0.067.
- So higher the significance level higher is the heterozygotes. In the absence of selection and genetic drift, all the frequencies within variables are constant. This principle was named by G, H Hardy.
According to the geological time span, the era which covers major history of the Earth is considered to be Precambrian era.
Answer: Option 3
<u>Explanation:</u>
Precambrian era is considered to be the most covering history of the Earth based on two factors, one is that it is longest era according to the geological time scale.
And as it is the longest era, major historical events of Earth are witnessed during this time. Precambrian era is known to be the beginning of formation of Earth which was about 4.5 billion years ago and it lasted for 542 million years ago.
