Both types of rocks form under high pressure, but metamorphic also requires heat.
Answer:
option c
Explanation:
A natural blind spot also called the optic disc in the eyes occurs where the blood vessels and axons of the ganglion cells leave to form the optic nerve. it is so called because there are no receptors (rods and cones) in this part of the retina. Artificial blind spots can also be formed when something prevents light from getting to the photoreceptors which are the rods and the cones.
This question is incomplete as no options are given. However, urbanisation typically leads to a greater percentage of impermeable surfaces, such as roads, parking lots etc. Water is then unable to filter into the soil and groundwater as much as it would on natural land. What then occurs is much more runoff in urban areas during rainfall. This has been problematic in major cities in the developing world, where storm water drains are not maintained. Rainfall can easily result in flooding, and floods can be much worse in urbanised environments. We must also consider that there will be reduced groundwater recharge in urban areas from rainfall, as less water infiltrates the soil. Interestingly, in urban areas, it is generally accepted that up to 60% of tap water is lost through leaks, many underground, so groundwater may be recharged through lost tap water.
I am not really sure, but I guess it is the temperature.
By using educated guessing, you can exclude brightness and age and also mass as they can vary and still cannot determine the other characteristics from one of them.
And also by knowing that pressure is known using equations only by temperature, and pressure actually can be considered to be responsible to form or deform the star.
Hope this helps.
