<u>From the given options which may suitably apply to the description of grid-lines of the map are
</u>
- They are measured in degrees
- They set up a reference system
- They divide Earth into four equal parts
Answers: Options A, B and E
<u>Explanation:
</u>
Option A describes that the grid-lines of the map are measure in degrees, which are very true as the grid are lined with angular measurement which thus be done in unit of angles and is in degrees only.
Option B says it develops the reference system which specifies about the area being plotted are grid depending upon the size which sets up the referential system of enumeration.
Option E is true as the world or the Earth has been divided into 4 equal parts through the Prime Meridian as the longitudinal line and Equator as the latitudinal line.
It is igneous rock. When magma cools, it solidifies into a rock called an igneous rock. They are formed when the hot, molten rock rises to the surface, it undergoes changes in temperature and pressure that causes it to cool, solidify and crystalize. Hope this helped you :)!
The answer is, I believe, the Grand Canyon.
Fossil records from separate continents, particularly on the outskirts of continents show the same species. As well mineral specimens along the supposed break lines of the continents are nearly identical. Some identical species exist on certain continents, like an earthworm common to both Africa and South America suggesting the species could not have spontaneously arisen on both continents without some variations.
<u>Answer:
</u>
The ranking of common igneous silicate minerals based on the temperature at which crystallization occurs is called Bowen’s reaction series.
<u>
Explanation:
</u>
In Bowen’s reaction series the minerals with high crystallization temperature are present at the top layer. This means these minerals are the first to crystallize from the magma and they are mostly unstable. The Bowen's reaction series is represented in the Y shape. The left branch of this Y has minerals containing iron and magnesium. They are called as Ferromagnesium minerals.
The right branch of the Y contains plagioclase feldspars minerals. Temperature gradually decreases down along the Bowen’s reaction series from 
to 
. At certain low temperature, the two branches combine forming minerals similar to felsic rocks such as orthoclase feldspar, quartz and muscovite mica.
