What do scientists know about fossils found in deeper layers of rock compared to
shusha [124]

Answer:

They know that layering, or bedding, is the most obvious feature of sedimentary rocks.  This Law of Superposition is fundamental to the interpretation of Earth history, because at any one location it indicates the relative ages of rock layers and the fossils in them. Layered rocks form when particles settle from water or air. That is kinda easy :D

What is the relationship of nitrogen and grass
fredd [130]

Nitrogen is the major nutrient required by grass and is used to stimulate high growth rates and is key to achieving high yields, however if too much nitrogen is applied this can have a negative effects on quality.

High rates of nitrogen can also cause problems with silage fermentation due to excess nitrate having a negative impact on the fermentation process and will produce silage that is less palatable and the animals will be less keen to eat it.

<span> <span> </span> </span> <span> Nitrate is generally taken up by grasses quicker than it is incorporated into proteins and until used this excess known as luxury uptake is stored in the leaves. Excess nitrate will be present if insufficient time is allowed between application and mowing and can also occur under conditions of poor growth eg low light levels, cool temperatures. It is also a problem if there is a dry spell after application, when nitrate cannot be taken up by the roots, followed by a period of wet weather that results in luxury uptake. The plant cannot convert it to protein quickly enough so it accumulates in the plant. </span>

High rates of nitrogen may cause a reduction in crop sugars as they are used to provide energy for the increased rate of plant growth and for the manufacture of plant proteins and this increased growth rate may in turn lead to lower crop dry matter content although in practice this is often not significant.

Excess nitrate can be avoided by following the Grassland Rule to apply nitrogen at the rate of no more than 2.5 kg N/ha/day.

What is the approximate temperature of the troposphere, mesosphere, and stratosphere.​
lakkis [162]

Answer:

Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere. This increase in temperature with height means warmer air is located above cooler air.
