In your own words, explain why you think that geologists find relative dating useful.

Fossils are important for working out the relative ages of sedimentary rocks. Fossils can help to match rocks of the same age, even when you find those rocks a long way apart. This matching process is called correlation, which has been an important process in constructing geological timescales. Relative dating is also used to arrange geological events, and the rocks they leave behind, in a sequence.

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
