Normally sometimes large farming lands
Answer:
6.0 to 7.0
Explanation:
A pH of 6.5 is just about right for most home gardens, since most plants thrive in the 6.0 to 7.0 (slightly acidic to neutral) range. Some plants (blueberries, azaleas) prefer more acidic soil, while a few (ferns, asparagus) do best in soil that is neutral to slightly alkaline.
Answer:
4. Glassy
5.phaneritic
6. Porphyritic
7. Alphanitic
Explanation:
Glassy or vitreous textures occur during some volcanic eruptions when the lava is quenched so rapidly that crystallization cannot occur. The result is a natural amorphous glass with few or no crystals. Examples include obsidian
Examples of aphanitic igneous rock include basalt, andesite and rhyolite.
Aphanitic rocks in contrast to phaneritic rocks, typically form from lava which crystallize rapidly on or near Earth's surface.
Porphyritic textures develop when conditions during cooling of a magma change relatively quickly
