Answer: Principle of Superposition

Explanation: In an otherwise undisturbed sequence of sedimentary strata, or rock layers, the layers on the bottom are the oldest and layers above them are younger. Principle of Original Horizontality: Layers of rocks deposited from above, such as sediments and lava flows, are originally laid down horizontally. Hope this helps!

In the Middle East, you can expect mainly earthquakes to happen. Earthquakes also result in other natural disasters such as mudslides and floods. To prepare for earthquakes, you can pratice what to do during an actual earthquake such as if you're a farmer and outside, you would want to get to an open area to avoid powerlines, trees, or anything that could come down. To also prepare for or prevent a mudslide, plant and water diversion are good methods to stay safe. You can also make sure you plant appropriately on hills. For floods, you can always ask others about relocation routes and centres. On top of that, if possible, you can prepare a household flood plan.

What is bowens reaction series

lesya692 [45]

<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 $1200^{\circ} \mathrm{C}$ to $700^{\circ} \mathrm{C}$ . At certain low temperature, the two branches combine forming minerals similar to felsic rocks such as orthoclase feldspar, quartz and muscovite mica.
