when a magma body intrudes into a rock body and pieces of the original rock body end up in the magma they don't fully melt and are incorporated as xenolith inclusions. are the xenoliths younger or older than the magma body
Is if xenoliths are found in a molten body, this indicates that they were present before the magma body formed. The xenoliths should therefore be older than magma body, according to the law of exclusions.
Describe xenoliths.A rock fragment encased in another kind of rock is known as a xenolith. A xenolith is typically a rock that became embedded in lava as it cooled. The molten rock that spews forth as lava during one volcano eruption is known as magma.
How can a xenolith be recognized?The addition must have a distinct composition from the surrounding rock in order to qualify as a xenolith. Autoliths or homologous inclusions are rocks that have comparable inclusions within them. Xenoliths are typically simple to identify.

what type of airfoil would you use for the wing? why?
Identical to those seen on high-performance F3B versions.
Why utilize this particular airfoil type?In theory, any airfoil can be used with flying wings and tailless model aircraft. But the airfoil needs to be carefully chosen if performance is a concern, as it is while competing. If the torsion moment of the airlift is balanced by the right ratio of wing sweep and twist, it is conceivable to employ the same airfoils that are used on high-performance F3B aircraft. The performance loss caused by sweep and twist can be reduced by selecting airfoils with moment coefficients cm c/4 that are near to zero.
In designing the MH 40 series and MH 60 series airfoils, the primary objectives were to (a) achieve low drag values comparable to typical airfoils used on F3B models, (b) cause only small torsion coefficients cm c/4, and (c) improve the maximum lift coefficient compared to existing, low cm c/4 airfoils.

Ocean acidification is responsible for damaging worldwide. O Boats and ships O Fishing nets O Coral reefs O Sand dunes O Beachfronts
Coral reefs are being harmed all around the world by ocean acidification. A coral reef is an underwater ecosystem that is made up of corals that construct reefs.
A coral reef is an underwater ecosystem that is made up of corals that construct reefs. Coral polyp colonies are bound together on reefs by calcium carbonate. [1] The majority of coral reefs are composed of stony corals, whose polyps gather together.
In the animal phylum Cnidaria, which also contains sea anemones and jellyfish, coral is a member of the class Anthozoa. For support and protection, corals secrete hard carbonate exoskeletons, unlike sea anemones. In warm, shallow, clear, bright, and agitated water, most reefs thrive. At the beginning of the Early Ordovician, 485 million years ago, coral reefs made their first appearance, replacing the Cambrian's microbial and sponge reefs.

A necessary ingredient for acid rain to occur is __________.
a. air pollution
b. heat pollution
c. runoff pollution
d. water pollution
Correct answer is :- Air pollution
When sulfur dioxide (SO2) and nitrogen oxides (NO2) are released into the atmosphere, they are carried by wind and air currents and eventually form acid rain. Acids made of sulfuric and nitric compounds are produced when the SO2 and NOX react with oxygen, water, and other substances. Before dropping to the ground, they then combine with water and other substances.
While volcanic eruptions and other naturally occurring processes do provide a minor amount of the SO2 and NO2 that create acid rain, fossil fuel combustion accounts for the majority of it.

What are the 5 golden rules of food safety?
The Five golden rules for Safer Food are: keep clean; separate raw and cooked; cook thoroughly; keep food at safe temperatures; and use safe water and raw materials.
1. Keep it Clean
WHO emphasizes that clean cooking practices must be followed in all circumstances. Unhygienic cooking practices can transfer dangerous microbes to your hands, cleaning cloths, kitchen utensils, and especially cutting boards. So have separate cutting boards for vegetarians and non-vegetarians. Also, be sure to wash and sanitize all surfaces and utensils before cooking.
2. Separate raw and cooked foods
Separating raw and cooked foods greatly reduces the risk of cross-contamination. Bacteria from raw foods can be transferred to hands and directly onto countertops, clothing and utensils before finally being transferred to heated foods.
3. Cook thoroughly
Proper cooking kills almost all microbes. Eating hot, glowing food is important because it has a low bacterial count. If the temperature drops below 70 degrees, the number of microorganisms increases significantly. Additionally, you should be careful not to cook food for too long. Otherwise, the nutritional value will be lost. The preferred cooking method to preserve nutritional value is steaming.
4. Keep food at safe temperatures
This means keeping the temperature at a level that minimizes or eliminates the number of bacteria. This temperature is about 60 degrees above and about 5 degrees below. It is important to keep food at safe temperatures and not store cooked food for long periods of time. Also, when consuming preserved food, heat it sufficiently (100°C) before consuming it. To prevent food poisoning, we recommend minimizing refrigeration of cooked foods and keeping cooked foods at room temperature for long periods of time.
5. Use safe water and raw materials
Always use clean water for cooking. Good safety practices include using clean water, choosing fresh and healthy foods, and choosing foods that have been processed for safety.

Answer:
Southwest Asia, Southeast Asia, and the Americas.
Explanation:
Major centers of domestication of plants and animals are Southwest Asia which also known as the Fertile Crescent, Southeast Asia, and the Americas. Plants and animals diffused globally because of the interaction of different cultures with each other. When the two different cultures interact with each other through migration from one region to the new one, both cultures exchanges some of the ways of living and methods. When the English people came to the New world, they introduced cultivation of corn crop which leads to diffusion of plants in the America.

What is a “jet stream"? What type of air does this one separate
Answer:
A jet stream is a type of air current that forms high in the atmosphere. On average, jet streams move at about 110 miles per hour. But dramatic temperature differences between the warm and cool air masses can cause jet streams to move at much higher speeds — 250 miles per hour or faster.
Explanation:
Jets streams play a key role in determining the weather because they usually separate colder air and warmer air. Jet streams generally push air masses around, moving weather systems to new areas and even causing them to stall if they have moved too far away.

What is light characterized as?
The characteristics of light are as follows. Light is an electromagnetic wave that propagates in a straight line in a process known as rectilinear propagation of light. Light is also a transverse wave, meaning that its particles move in the opposite direction to the direction of the wave's propagation.
Actually, radiation, which is defined as energy that moves as electromagnetic waves, includes visible light. Another way to think of it is as a continuous flow of particle-like "wave-packets," or photons, that move at the speed of light (about 300 000 kilometers per second).
The energy that moves in waves is called light. Many of the characteristics of light are determined by its length or wavelength. For instance, the wavelength determines the color of light and its interaction with matter.
