All the spheres on earth overlap with each other so that any changes occur in one sphere may affect the other.
<u>EXPLANATION: </u>
The four spheres of earth are Land (the lithosphere), water (hydrosphere), air (atmosphere), living things (biosphere). The living organisms receive sunlight, heat, and gases from the atmosphere and water from the hydrosphere.
All these spheres are interlinked with one other and assembles in a single location at the time of overlapping. Life would not be there on earth if all these spheres do not interact or overlap with each other.
Examples of the earth overlapping is given below;
- Birds the living organism that flies in the air.
- Water flows through the soil on land.
- Evaporation of water into the atmosphere causes rain on the land.
D. Brain activity doesn't necessarily cause behaviour just because they coincide.
Explanation:
- Neuroscience is the study of the neurons. This deals with how the nervous system develops, the structure of the nervous system and its actions.
- Neuroscientists are focusing on the brain and its impact on cognitive functions and behaviour.
- Scientists proved that the chemicals present in the brain are responsible for our general state and mood that we are going through. Damage of brain cell will affect our impulses and the impulsive behaviours.
Answer:
Explanation:
The nitrogen cycle is an important cycle to the atmosphere. Nitrogen is an essential part of biological molecules such as proteins and nucleic acid, which makes nitrogen essential for all living organisms. Nitrogen makes up 78 percent of the atmosphere.
