Answer:
They indicate the number of each chemical species that reacts or is formed. Methane and oxygen (oxygen is a diatomic — two-atom — element) are the reactants, while carbon dioxide and water are the products. All the reactants and products are gases (indicated by the g's in parentheses).
the answer is D. because a topographic map measures the lowest and highest points in a certain place
Hope this helps
Answer:
- Rock composition
- Exposed surface area
Explanation:
Although there are other factors involved, I have selected two most important factors that could play a vital role in the resistance of the rock weathering. Here I have discussed each of them briefly.
<em>Rock composition:</em> If a rock is compact and composed of minerals which are not easy to disintegrate by physical as well as chemical weathering, it will increase the resistance of natural rock weathering process. For example, if a rock is composed of high silica content, it will not easy weathered as compared to the rock which is composed of feldspar, calcite, and/or iron. Likewise, igneous rocks are more resistant to the sedimentary rocks because the minerals composition is more compact and dense.
<em>Exposed surface area: </em>If a rock is exposed to the natural environment, it could be weathered more quickly then the rock which is not exposed directly (e.g. underlying rocks). Therefore, covering a rock surface or reducing the surface area could contribute towards increasing resistance of rock weathering. This is the reason that deep underlying rocks stay intact for a longer period of time as compared the those which are exposed.

Heat emission by stars.</h2>
Explanation:
The given statements summarize to the following points -
- Electromagnetic radiation is measured in arrange to recognize components of space which is not visible optically, such as the sum of warm a star is radiating or heat emitted by the stars.
- Cosmologists utilize the complete electromagnetic range to watch a different type of thing related to the planet or outer space bodies.
- Radio waves and microwaves – the longest wavelengths and least energies of light – are utilized to peer interior thick interstellar clouds and track the movement of cold, dim gas.
- During the carbon cycle, the carbon is transferred across the biosphere. Plants change over CO2 to oxygen and glucose through photosynthesis. Carbon is a chemical component, like hydrogen and oxygen. Carbon is present in all living things – such as creatures and plants or the biotic component – as well as the ocean, soil, and rocks or the abiotic component. Carbon dioxide is a gas made up of the components of carbon and oxygen. Hence, the other elements that should be present are oxygen and hydrogen that will make other planets similar to that of earth.
