Explanation:
Specular Hematite is a mineral which is found in rocks and soils. The crystal of specular hematite is greyish black in color but it can form the streak of reddish color which is due to the presence of iron oxide. It has metallic luster which gives a look like silver and has shiny flakes.
TWO social, political, or cultural conditions necessary for the success of the agricultural practices/technologies of the green revolution:

- Stable government and political environment
TWO significant economic or ecological factors that may limit the long-term success of the agricultural practices/technologies of the green revolution:
- Expensive pesticides and fertilizers
- Water pollution and decline of soil fertility due to erosion
Explanation:

The correct answer is - 43%.
The increase in CO2 between these two suggested periods is approximately 43%. Even though it is a natural process that the CO2 levels vary in the atmosphere, still this is not the same case nowadays. Nowadays, or rather in the past few decades, apart from the natural increase of CO2 in the atmosphere, it has seen a much more increased levels because of the human activity. The industrial facilities and the vehicles, the cutting of the forests and burning the wood (there's both release of CO2 from the burning of the trees and loss of natural accumulator of the CO2), are just some of the more important human activities that contribute to a significant rise in the CO2 levels.
The texture of sedimentary rocks, like the size of grains or chemical precipitates can show how the rock was formed. The fossils of sedimentary rocks can show when the rock was formed. The stratification and sorting of the particles can show were the rock was formed.
