Answer:
Once the fusion reactions begin, they exert an outward pressure. As long as the inward force of gravity and the outward force generated by the fusion reactions are equal, the star remains stable.First, stars fuse hydrogen atoms into helium. Helium atoms then fuse to create beryllium, and so on, until fusion in the star's core has created every element up to iron.
Answer:
Stars create new elements in their cores by squeezing elements together in a process called nuclear fusion. First, stars fuse hydrogen atoms into helium. Helium atoms then fuse to create beryllium, and so on, until fusion in the star's core has created every element up to iron.

Answer:
An endangered species is one whose numbers are so small that it is at risk of extinction.
A species is defined as endangered or threatened when it is suffers from these factors: damage to its habitat for recreational, or entertainment purposes; disease or predation of the species; and hazards to the continued life of the species.
A species is declared extinct after many years of not being spotted. Because it takes so long to define an entire species as extinct, it is probable that there are many species already gone that we are unaware of.
Rangers are on the frontlines of conservation to protect some of the world's most endangered species like tigers, elephants and rhinos. Send thank-you cards to those who protect endangered species. Sign up for Wildlife Cards!
Extinction is a natural phenomenon, it occurs at a natural “background” rate of about one to five species per year. Scientists estimate we’re now losing species at 1,000 to 10,000 times the “background” rate, with dozens going extinct every day.
As many as 30 to 50 percent of all species are possibly heading toward extinction by mid-century.

Answer:
Oceanic crust and Continental crust
Explanation:
Earth's crust is divided into two types: oceanic crust and continental crust. The transition zone between these two types of crust is sometimes called the Conrad discontinuity. Silicates (mostly compounds made of silicon and oxygen) are the most abundant rocks and minerals in both oceanic and continental crust.

What was the significance of the Yazoo Land Act?
Answer:
The Yazoo land fraud was one of the most significant events in the post–Revolutionary War (1775-83) history of Georgia. The bizarre climax to a decade of frenzied speculation in the state's public lands, the Yazoo sale of 1795 did much to shape Georgia politics and to strain relations with the federal government for a generation.
Explanation:
History copied from a book...
Sorry if it's wrong
Answer:
Yeoman farmers and speculators were eager to move into this land. The Georgia government promised land to both individuals and speculators–more land than they actually had to give. The Yazoo Land Act was passed to try and fix this problem.

Triangle angle-sum theorem
Find m<1
Answer:
123 Degrees.
Explanation:
This is basically the Exterior Angle Theorem which basically states that the exterior angle (m<1) is equal to the sum of the 2 opposite interior angles. (60 & 63).
Following this theorem your equation should look something like this -
Exterior Angle = Opposite Interior Angle + Opposite Interior Angle.
Plug in the numbers and you'll get -
m<1 = 60 + 123
m<1 = 123

Which type of climate would cause the greatest rate of physcial
(mechanical) weathering?
O Cold and humid (wet)
O Cold and dry
O Warm and dry
O Warm and humid (wet)
Answer:
Cold and dry climate causes the greatest rate of physical (mechanical) weathering.
Explanation:
The first option is not correct because these climates have a relatively slow rate of weathering.
The second option is correct because these climates have the highest rates of mechanical weathering, which is primarely because of the exposure of the rocks to the very strong winds that blow almost always.
The third option is not correct because the rate of mechanical weathering is not very high, yet alone the greatest.
The fourth option is not correct despite these climates having the highest weathering rates, generally speaking when it comes to the mechanical weathering they slightly fall behind the cold and dry climates.
cyclonic rainfall and its features
Answer:
This occurs due to the convergence of different air masses with different temperatures, density, and humidity. The turbulent conditions are produced, and cyclonic rain occurs along the fronts of the cyclone. The layer separating them is known as a front. The front has two parts – the warm front and the cold front.
At the warm front, the lighter warm air that is less dense usually forced to rise over denser cold air and thereby leading to cyclonic rain. A variety of clouds get formed, and they generally lead to moderate to heavy rainfall.
Causes for Occurrence of Frontal Rainfall
A tropical warm air mass comes in contact with a cold air mass of polar region. The less-dense, lighter warm air is then forced to rise over the denser, cold air.
It causes warm air to become cold. As the warm air is forced to rise further, it condenses to form the stratus cloud.
After becoming saturated, the stratus cloud begins to precipitate.
Frontal or cyclonic rain falls gradually for a few hours which can also extend up to a few days.
It is prevalent in Britain and Ireland, which is associated with the movement of depressions over the country. In north-west Europe, warm oceanic air and cold continental air converge to produce heavy rainfall in adjacent areas.
