Because the lava cools quickly, there is no time to create big crystals of Basalt, which means that only small ones that are not visible to the naked eye exist, which means that it has an <span>aphanitic texture.</span>
Answer: Helps the plant breathe: The epidermis of the leaf contains guard cells that control and regulate the small pores on the undersurface of the leaves. These pores are called stomata. Stomata are responsible for regulating water in and out of the cell. It is also responsible for the exchange of gases across the epidermis.
First of all, the cohesive and adhesive properties of the water molecules fascilitate this. Water molecules stick together and with the walls of the vessels, creating a column of water which doesn t break easily. Moreover the xylem vessels of the tree are very narrow increasing the pressure. Finally, transpiration is taking place as water from the leaves evaporate, thus a continuous osmotic gradient is being created, causing water to be drawn up the tree
Cohesion hold H Bonds together to create surface tension on water. And since water is attracted to other molecules it then sticks to other molecules.
hope i helped
