The slope of the line is m = -1
<u>Basalt</u>
<em> </em><em>Formation</em> -basalt is (mineral) a hard igneous rock of varied mineral content formed when lava reaches the Earth's surface near an active volcano
<em> </em><em>Texture</em>- is fine grained so the individual minerals are not visible
<em> </em><em>Colour</em>- basalt being dark
<u>Rhyolite</u>
<em> Formation</em> -Rhyolite is a very fine-grained to glassy extrusive igneous rock. Formed in continental plates have volcanic eruptions.
<em> Texture</em>- very small than grains and are difficult to observe without using a hand lens.
<em> </em><em>Colour</em>- light in colour whether pink or grey
<u>Andesite</u>
<em> </em><u><em> </em></u><em>Formation</em>- Andesite is a fine-grained igneous rock that forms when the magma is rises up onto the surface and crystallized quickly
<em> </em><em>Texture</em>- higher than basalt and lower than rhyolite
<em> </em><em>Colour</em><em> -</em>- color is pale due to silica content
Answer:
A
Explanation:
The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, Colombia with 10%.
The index fossils are fossils that are found in the rock strata of certain geologic period, but they are also fossils that are very common and can be found in numerous places around the globe.
Because they can be found all over the globe, and they are indicative of certain geologic period, the geologists have started to use them as a simple way of determining the age of the rock strata. While this method can not provide the geologists with an accurate year for the formation of the rocks, it is still able to determine the relative age of the rocks. By determining the relative age with such ease by using the index fossils, the geologists are able to immediately make conclusions about the rock strata, have basic information about it, and largely be aware of the processes that formed them and influenced them.
