The image of the different rocks are attached. From the image attached, it can be seen that rock 1 and rock 5 have a fine grained texture.
Fine grained rocks are formed from volcanic eruptions. During these eruptions, the molten magma is cooled fast at or close to the earth surface thereby forming rocks with a fine grained texture. The rock has fine grains because the crystals are small because of the fast cooling of the molten magma. Slow cooling causes the crystals to be large thereby forming coarse rocks such as rocks 2, 3 and 4.
An anemometer will be used to measure the speed of the wind.
<u>Explanation:
</u>
An anemometer is a simple device used to measure the speed of the wind by most meteorologists. The structure of this device is simple as it has three or sometimes four cups attached using horizontal strips made up of steel to a vertical rod.
As the wind blows over the cups, the cups are pushed by the wind making them move. Hence, the vertical rod moves as the wind blows. The revolutions of the vertical rod for a specific time are counted and averaged in order to determine the speed of the wind.
