Answer:
Breathing – It is the physical process, through which all living organisms, including plants, animals and humans inhale oxygen from the outside environment into the cells of an organism and exhale carbon dioxide back into the atmosphere.
Decomposition: It is one of the natural and most important processes in the oxygen cycle and occurs when an organism dies. The dead animal or plants decay into the ground, and the organic matter along with the carbon, oxygen, water and other components are returned into the soil and air. This process is carried out by the invertebrates, including fungi, bacteria and some insects which are collectively called as the decomposers. The entire process requires oxygen and releases carbon dioxide.
Combustion: It is also one of the most important processes which occur when any of the organic materials, including fossil fuels, plastics and wood, are burned in the presence of oxygen and releases carbon dioxide into the atmosphere.
Rusting: This process also requires oxygen. It is the formation of oxides which is also called oxidation. In this process, metals like iron or alloy rust when they are exposed to moisture and oxygen for an extended period of time and new compounds of oxides are formed by the combination of oxygen with the metal.
Explanation: The Stages
Stage-1: All green plants during the process of photosynthesis, release oxygen back into the atmosphere as a by-product.
Stage-2: All aerobic organisms use free oxygen for respiration.
Stage-3: Animals exhale Carbon dioxide back into the atmosphere which is again used by the plants during photosynthesis. Now oxygen is balanced within the atmosphere.
Plate tectonics is a theory that the Earth's outer crusts are divided into seven plates that glide over the mantle. They are often blamed for earthquakes.
Answer:
They are used to find the distance between two hills.
Explanation:
Scale bars in a topographic map is used to find the distance between two hills.
The bar shows the relationship between ground distance and that map distance.
- When we compare the distance measured on map with the scale given, we can find the true distance on land.
- Scales are mostly used for abstracting the real world.
The igneous rock, if it has pushed its way, as a magma into the surrounding sedimentary rock such as a sandstone or a limestone and cooled off, will have a relative age as younger than the sedimentary rock. Also, if the igneous rock has altered the sedimentary rock at their contact, then the alteration will have a similar age to the igneous rock age.
