Earthquakes and volcanoes are more commonly found near the edges of continents, along tectonic plate boundaries. However, they can also occur within the interior of continents but to a lesser extent.
Earthquakes and volcanoes are not evenly distributed around the world. They tend to occur along tectonic plate boundaries, which are located near the edges of continents. The majority of earthquakes and volcanoes can be found along the Pacific Ring of Fire, which is a region of high tectonic activity that encircles the Pacific Ocean. This region includes countries like Japan, Indonesia, the Philippines, and Chile.
In addition to plate boundaries, there are also intra-plate earthquakes and volcanoes that occur within the interior of continents. These are relatively less frequent compared to those along plate boundaries. Examples of intra-plate earthquakes include the New Madrid earthquakes in the United States and the earthquakes in the Indian subcontinent. Intra-plate volcanic activity, on the other hand, is rare but can occur in places like the Yellowstone National Park in the United States.
Overall, earthquakes and volcanoes are more commonly found near the edges of continents, along tectonic plate boundaries, but can also occur within the interior of continents to a lesser extent.

Answer: Cynobacteria
Explanation:
The Precambrian time is the earliest period of earth history. It is preceded by the Cambrian time hence got the name. The earliest living organism in the Precambrian time was the Cynobacteria. It has been found in the fossil record of 3.4 billion years ago. They were the primitive organisms which were capable of conducting photosynthesis and producing oxygen. The abundance of Cynobacteria has resulted in the increase in abundance of oxygen into the atmosphere.
Explain it in full detail.
Answer:
Biotic factors can be described as the living components of a system. Abiotic factors can be described as the non- living components of an ecosystem. The abiotic and biotic components of an ecosystem are linked to each other by the flow of energy.
Energy usually enters an ecosystem through the abiotic factor, i.e Sun in the form of heat. This energy is essential so that the biotic component, plants, can make their own food. Some of the heat energy is dissipated back into the atmosphere in the form of heat. Rest, the energy is directed to herbivores, carnivores and decomposers. All these organisms also dissipate some of the heat energy back into the atmosphere.
