Explanation:
Why are grassland and savanna fires not like forest fires? Support your answer with what is currently happening in southern France.
Savanna fires keep tree cover low and control forests from encroaching on the grassland. When tree cover is high, as in a forest, fires cannot apply as easily, halting the savanna's advance into the forest
What causes fires in most savanna grassland?
These fires are usually lit by cattle growers as part of their traditional management of the Savannas where their animals graze.
How is fire wrong for a savanna grassland?The researchers found that the commonness of fires determines whether forest or savanna will dominate an area more than other factors such as rainfall, seasons and soil texture, particularly in areas with moderate precipitation.
Regular fires prevent trees from setting and savannas from turning into forest.

how might the actions of a group like jundallah promote the denial of rights to sunni groups in iran
The actions of the Jundallah group may limit the rights of Sun.nis because they may spread a biased perception of the Sun.ni community to the government.
Who are the Jundallah?Jundallah is an Islamic group formed in 2005 in the provinces of Sistan and Balochistan (Iran). The main reason for the formation of this group is the accusation against the government of the Shi.ite regime of abandonment and discrimination against the Sun.nis and their provinces.
According to the above, it can be inferred that this group has contributed to promoting the denial of the rights of the Sun.ni community because by calling themselves Sun.nis, they cause a biased perception of this community in the government.
So the government can see the Sun.ni community as a whole as rejecting their government and blaming it and denying them some rights as a result of their uprising.

Discuss in detail the impact of European farm animals on the ecosystems of Oceania. Why have the Dingo fence and the Rabbit Proof fence been necessary in Australia.? What does this tell us about the vulnerability of Oceania’s environment to invasive species, and toe changing patterns of food consumption based on introduced domesticated animals? Finally, why are coral reefs such as the Great Barrier Reef ecologically important to the coastal zones of Australia, and how are they threatened by climate change
The evolution of flora and fauna across the islands of Australia and Oceania is very unique.
Many species of plants and animals reached the southern Asian islands during the last ice age, when sea levels were low enough for travel. THE DINGO Fence was built to keep dingos out of sheep pastures in South East Australia. As Australia's largest terrestrial predator, dingoes pose a major threat to livestock.
The Rabbit Proof Fence was built to protect Western Australia's crops and grasslands from rabbit disease. Introduced to Australia in Victoria in the 1850s, the pest quickly spread throughout eastern Australia.
They are home to a quarter of the ocean's marine life, generate clean air and protect vulnerable coastlines from erosion, flooding and storms. In Australia, our Great Barrier Reef is an irreplaceable and vital part of our ecosystem - and our economy.

Answer:
pollution
phosphorus from farmers
pollution
A chemical process that starts when gases like sulfur dioxide and nitrogen oxides are discharged into the atmosphere leads to acid rain.
What is a acid rain?Acid rain, also called acid precipitation or acid deposition, precipitation possessing a pH of about 5.2 or below primarily produced from the emission of sulfur dioxide (SO2) and nitrogen oxides from human activities, mostly the combustion of fossil fuels.
Acid deposition can impair biodiversity and lower the pH of surface waters in acid-sensitive areas. It weakens trees and makes them more vulnerable to harm from other stressors including drought, extremely cold weather, and pests.
In acid-sensitive locations, acid rain can also liberate aluminum linked to soil particles and rock in its deadly dissolved form, depleting soil of crucial plant nutrients and buffers like calcium and magnesium.
Some power stations are altering the way they burn coal since burning coal and other fossil fuels produces nitrogen oxides.
Making electricity without the use of fossil fuels is an excellent technique to lessen acid rain. In its place, individuals can use renewable energy sources like wind and solar energy.

Which of the following is not a true statement about mineral properties?
- Calcite dissolves rapidly releasing visible bubbles of carbon dioxide gas so the acid test is useful for identifying if the mineral calcite is present.
- Luster is the way in which a mineral reflects light.
- Some minerals have a natural magnetism such as a magnetite which is why geologists test minerals with magnets to check for this characteristic.
- Pyrite has a metallic luster and is a yellowish mineral but it will not streak the same color as gold.
- Fluorescent minerals emite visible light when they are exposed to radiation.
Please explain!
The sentence that is not a true statement about mineral properties is option A. Calcite dissolves rapidly releasing visible bubbles of carbon dioxide gas so the acid test is useful for identifying if the mineral calcite is present. Hence, the correct answer is option A. Read below why option A. is the sentence that is not true of the minerals.
Why is option A not true?The bubbling release of carbon dioxide gas is so weak that one needs a hand lens to observe single bubbles slowly growing in the drop of hydrochloric acid - or so vigorous that a flash of effervescence is produced. This is the case as against the proposition stated in the option that it is visible whereas, it is not visible without a hand lens.
Therefore the correct answer is as given above.

Answer:
The statement "Pyrite has a metallic luster and is a yellowish mineral but it will not streak the same color as gold" is not a true statement about mineral properties.
In reality, pyrite, also known as fool's gold, does have a metallic luster and is often a brassy yellow color. However, when pyrite is streaked on a streak plate or any other rough surface, it leaves a greenish-black or dark gray streak, which distinguishes it from gold. Gold, on the other hand, leaves a golden-yellow streak.
Explanation:
The other statements you mentioned are true:
Calcite does dissolve rapidly in acid, releasing visible bubbles of carbon dioxide gas, which makes the acid test useful for identifying its presence.Luster refers to the way in which a mineral reflects light, and it is one of the important properties used in mineral identification.Some minerals, such as magnetite, exhibit natural magnetism, and geologists can use magnets to test for this characteristic.Fluorescent minerals do emit visible light when exposed to certain types of radiation, which is why they are used in fluorescent mineral displays.Remember that understanding the properties of minerals is crucial for their identification and classification in the field of geology.
Understanding the properties of minerals is an essential aspect of mineralogy and geology. Here are some additional details about mineral properties:
Hardness: Hardness is a measure of a mineral's resistance to scratching or abrasion. It is often assessed using the Mohs scale of hardness, which ranks minerals from 1 (softest) to 10 (hardest). For example, talc has a hardness of 1, while diamond has a hardness of 10.Cl34vage and Fracture: Cl34vage refers to the way a mineral breaks along planes of weakness, producing smooth, flat surfaces. Fracture describes the manner in which a mineral breaks when no cl34vage planes are present, resulting in irregular or rough surfaces.Color: Color can be a useful property for identifying minerals, but it can also be misleading. Many minerals exhibit a range of colors, while others may be colorless. Additionally, impurities within a mineral can cause variations in color.Streak: Streak refers to the color of a mineral's powder when it is scraped across a rough surface. It is often determined by rubbing the mineral on a streak plate, which is an unglazed porcelain tile. Streak color can differ from the mineral's external color and can aid in identification.Density: Density is the measure of a mineral's mass per unit volume. It helps distinguish between minerals with similar appearances but different compositions. Density is typically reported in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).Crystal Habit: Crystal habit refers to the characteristic shape and arrangement of crystals in a mineral. Different minerals exhibit distinct crystal habits, such as cubic, prismatic, tabular, or fibrous.Specific Gravity: Specific gravity is the ratio of a mineral's density to the density of water. It provides a measure of a mineral's heaviness compared to water and can aid in identification.These properties, among others, contribute to the identification and classification of minerals. It's important to note that some properties, such as luster and streak, are observable with the bare eye, while others, like hardness and specific gravity, may require specialized tools for accurate measurement.
