1.) the geologic time scale is a system of chronological dating that relates geologic structure to geologic events. it is a model because it measures and describes events and relationships in geologic history.

2.) the paleozoic period was roughly from 245 million years ago to 545 million years ago.

3.) the dinosaurs lived in the mesozoic era, specifically the triassic period, which was roughly around 230 million years ago.

4.) the first early human relatives were found roughly around d the neogene period, about 25 million years ago, and is in the cenozoic era.

( 15 points to whoever replies quickest no links pls ) a farmer has used a fertiliser containing ammonium nitrate, potassium nitrate and ammonium sulphate on his fields but some may have leached into a nearby river. If a sample of river water was tested, what colour would the flame be if there was fertiliser contamination

Answers

If water of the river was tested there would be orange color flame.

What is fertilizer?

Millions of tons of air, natural gas, and mined ores are transformed into plant nutrition products based on the three crucial nutrients nitrogen, phosphorus, and potassium by the fertilizer industry.

The process begins by combining nitrogen from the air with hydrogen from natural gas at high temperature and pressure to produce ammonia, which is then used to make nitrogen-based fertilizers, the largest product category. Natural gas is used as a raw material for about 60% of the time, while the remaining 40% is used to power the synthesis process.

The nitric acid created from the ammonia is combined with it to create nitrate fertilizers like ammonium nitrate (AN). Urea can also be made by combining ammonia with liquid carbon dioxide. To create UAN (urea ammonium nitrate) solution, both of these products can be combined with water.

Therefore, If water of the river was tested there would be orange color flame.
