Answer:
its a ray line me child u-u
Explanation:
Answer:
its a ray line I know this because as you can see there is a dot and a endless line pointing the other direction showing that this is a ray --->
A line is a closed figure meaning dot line dot
Answer:
Province 2
Explanation:
Coral polyp colonies, often known as coral reefs, number in the hundreds to thousands. These sessile (fixed in one spot permanently) marine invertebrate creatures have strong calcium carbonate exoskeletons.
Coral reefs offer chances for recreation, serve as a barrier against erosion and storm damage, and support local economies. They are also a source of fresh medications and food. More than 500 million people rely on reefs for safety, income, and food.
Thin calcium carbonate layers make up a coral reef.
Over a skeleton made of calcium carbonate, coral polyps create a living carpet. The corals most in charge of creating the groundwork for and erecting reef structures are known as stony corals (or scleractinians).
When free-swimming coral larvae cling to submerged rocks or other hard surfaces along the margins of islands or continents, coral reefs are first formed. Reefs develop one of three main structural types as the corals swell and grow: fringing, barrier, or atoll.

Answer:
Cleavage of a mineral is defined as the direction along which the mineral breaks over the flat mineral surface. It is directly dependent on the mineral's crystallographic structure.
Slaty cleavage refers to the cleavage that is commonly found in the low grade metamorphic rock slate. Here, the fine grained minerals are so closely spaced and the lines of weakness are all parallel to each other, that allows the minerals to break in fine and thin layers. During the time of formation of slate, the smaller fractures are formed due to the increasing pressure. When groundwater moves through these fractures it forms a weak zone due to which these slaty cleavage forms.
When the rocks undergoes deformation and changes in the pressure and temperature condition then the cleavages are formed on the mineral's surface. The calcite contains rhombohedral cleavage are considered to be the perfect cleavage. Whereas the cleavage in amphibole is uneven and comprised of two directions that intersect each other at 56° and 124°.
Answer:
Ozone
Explanation:
Ozone is a secondary photochemical contaminant, that is, it is formed from primary pollutants emitted into the atmosphere (mainly nitrogen oxides and volatile organic compounds) in the presence of solar radiation.
The photochemical formation of ozone in a given region is the result of a complex chemical process in which, from its precursors (nitrogen oxides and volatile organic compounds), a multiplicity of different species intervene, interacting with each other according to different reactions, resulting in a highly nonlinear final balance. A transcendental consequence of this nonlinear chemistry is that in a given region, and depending on the initial conditions of departure, the action on the different precursors can have very variable consequences, it being possible that it leads both to an increase and a decrease of ozone concentrations.
This makes short-term measures to reduce air pollution in a certain area, of a restrictive type (such as limiting the operation of heat generators, restricting the circulation of vehicles, regulating traffic to make it more fluid, restricting certain industries and activities) they are not as effective with ozone as with other types of pollutants, as they are a secondary type pollutant and may even in some cases produce a counterproductive effect: for example a drastic reduction in traffic, causing a decrease in NOx levels in the atmosphere, can prevent the decrease of ozone levels that had previously formed.
In the fight against ozone it is necessary to apply medium and long-term measures aimed at limiting emissions of ozone precursor pollutants into the atmosphere.
They do not serve short term strategies. Medium-long term strategies for the reduction of ozone precursors must be devised:
- Less polluting vehicles (NOx, VOCs)
- Use of public transport (NOx, VOCs)
- Energy saving (NOx)
- Use of non-polluting energies (NOx)
- Reduction of solvent use (VOCs).
