Some of the main minerals in igneous rocks are feldspar, quartz, olivine and mica. The size of the minerals depends on the depth of the magma that formed the rock. Deeper magma cools more slowly and forms larger crystals. Rocks that cool over a few months have microscopic mineral grains and are called extrusive. Rocks that cool over thousands of years have small to medium grains and are called intrusive. Rocks that cool over millions of years have large pebble sized grains and are called plutonic.
Granite and basalt make up the majority of igneous rocks. Basalt is dark and fine-grained with minerals rich in magnesium and iron. It is either extrusive or intrusive and is the primary rock on the ocean floor. Granite is light and coarse-grained and rich in feldspar and quartz. It is plutonic and less dense than basalt. Granite is found nearly everywhere beneath the continents.
The word "igneous" comes from the Latin word "fire" and is related to the melting process that forms these rocks.

The given statement "An AED should only be used if a person is too tired to continue with chest compressions" is false.
Answer: Option B
<u>Explanation:</u>
Most people think that they are very tired after applying the compress for 2-3 minutes. When the compressor is tired, it tends to compress more slowly. For this reason, rescuers are advised to do compressions in every 2 min to prevent fatigue and optimise the compressions quality. This should only be done if the person does not show signs of life or is dead, does not respond and breathes normally.
For example, consider you come across the victim in a narrow place and you have two helpers: Rescuer 2 arrives with the AED (automated external defibrillator) and puts it on the opposite side from Rescuer 1, who does chest compressions. Rescuer 2 turns on the AED and fixes the electrodes to the victim's chest, connecting wires to the AED if necessary. Rescuer 1 can continue CPR (Cardiopulmonary resuscitation) by placing electrodes until the victim's heart rate has been analysed.
