Answer:
In 1749 A.D. George Wofan, a French scientist, put forward the theory of evolution of the Earth for the first time. According to his theory the Earth along with other planets and satellites, was formed when a comet moving around the universe stroke the sun many years ago.
Explanation:
In 1775 A.D., a German philosopher Kant put forward another nebular theory, which was later improved by Laplace in 1796. According to him, there was a gaseous mass revolving around the earth. While revolving, this mass began to cool and shrinked resulting many smaller masses. These smaller masses began to move round the larger central mass. This central mass became the sun and over revolving bodies formed planet and satellites.
According to hypothesis proposed by Jeans and Jeffery in 1917 A.D., a big star orbiting round the sun finally approached it. The star with its own attraction caused a tide to be developed from the sun. As this fragmented tidal matter cooled, planets, satellites, etc. were formed and the solar system was created. In this process, the Earth was also formed.
Any two geological Era are as follows:
Palaeozoic era: Palaeozoic era was began from 540 million years ago and ended at 250 million years ago. In this era, the plants and animals were found tohave developed which was found from the studies of the fossils remained in sedimentary rocks. Similarly, it is also believedthat there was a change in atmosphere and whether. This era is divided into six periods.
Mesozoic era: Mesozoic era began from 250 million years ago and ended at 65.5 million years ago. In this era, different types of hills and mountains were formed. It is supposed that the vital conditions for the survival of life on land, water and air were formed. This era is divided into three periods.

c. mechanical weathering.
d. carbonation
Answer:
[tex]\huge\boxed{\sf Acid \ Rain}[/tex]
Explanation:
Oxides of sulfur and nitrogen combine with air and water vapors to produce more acidic substances (low pH) and consequently, acid rain is produced which can be of great damage for the living and non-living things on the Earth.

~AH1807Peace!Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which statement best describes an environmental consequence of this process?
A. Chemicals added to the liquid can contaminate groundwater.
B. Wastewater is contaminated with oil and becomes sludge in landfills.
C. Water vapor is released into the air, which is considered a greenhouse gas.
D. Heavy metals are released into surrounding soil, poisoning local vegetation.
Answer:
Option A, Chemicals added to the liquid can contaminate groundwater, this statement best describes an environmental consequence of this process.
Explanation:
Fracking is a process of digging fossil energy sources, which need a lot of water and uses local water resources. It is drawn with high-pressure water, sand and elements, creating high pressure to block the porous rock and discharge gas. The spill itself stops energy from the drilling position, and may even make earthquakes, mainly due to the pumping of overflowing wastewater into porous rock types such as limestone. The most significant result of water distortion is on groundwater.To learn more about fracking, refer:

Which approach is most directly concerned with assessing the relative contributions of heredity and experience to personality development?
a. biological
b. cognitive
c. biopsychosocial
d. psychodynamic
The biopsychosocial approach is most directly concerned with assessing the relative contributions of heredity and experience to personality development (Option C)
The Biopsychosocial Approach is an interdisciplinary model which was first developed by George Engel and Jon Romano (1977).The biopsychosocial approach is a type of model that recognizes biological (inheritance), psychological, and social (environmental) factors as well as the interactions among these factors to understand the health and illness state of an individual.Social factors include economical, environmental, and cultural factors (e.g. work concerns and family issues).Biological factors include both genetic and biochemical factors.According to this approach, both mind and body determine the health of the subject.Learn more in:

Answer:

If you see reindeer, lynx, bear, and conifers, you're probably in a biome taiga.
What is taiga?The Taiga or boreal forest is a biome formed mainly by conifer-type plants, so it is also called the Coniferous Forest.
The climate in this region is subarctic, characterized by a very cold, long and dry winter with temperatures reaching -50º C. Summer is short and humid, days are longer and temperatures can reach 20º C.
With this information, we can conclude that if you see reindeer, lynx, bear, and conifers, you are probably in a taiga.

Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which
statement best describes an environmental consequence of this process?
• Chemicals added to the liquid can contaminate groundwater.
O Wastewater is contaminated with oil and becomes sludge in landfills.
Water vapor is released into the air, which is considered a greenhouse gas.
Heavy metals are released into surrounding soil, poisoning local vegetation
The correct answer is that chemicals added to the liquid can contaminate groundwater.
Fracking is a method of drilling fossil energy resources, which requires a lot of water and consumes local water resources. It is pumped with high pressure water, sand and chemicals, causing high pressure to block the porous rock and release gas.
The water spill itself destroys nature from the drilling site, and may even cause earthquakes, especially due to the pumping of abundant wastewater into porous rock types such as limestone. For example, Oklahoma appears to have become a special earthquake risk area. The biggest impact of water distortion is on groundwater. In Wyoming, USA, the same chemicals found in groundwater have been found in groundwater, and some of them are toxic or carcinogenic.

Most chemical reactions within cells do not occur spontaneously. Instead, they need a catalyst to get them started. Why do you think this is so?
Answer:
A catalyst is a chemical involved in, but not changed by, a chemical reaction. Many enzymes function by lowering the activation energy of reactions. By bringing the reactants closer together, chemical bonds may be weakened and reactions will proceed faster than without the catalyst.

Students have a small steel ball and a large steel ball, and they have a short ramp and a tall ramp.
The students want to find out if a ball's size affects how far it can roll. They also want to find out if the height of the ramp affects how far the ball can roll.
They do the following experiment:
**Written Response** What can they conclude from this experiment? Why?
Answer:
I think the height of the ramp affects the distance that the ball can go, but the size doesn't affect it
and as you decrease th height of the ramp it will look like straight thing, when it look like that the ball might need a little force in order to get speed also to go far
but in this condition the size can affect the ball distance it also depends on how much you give to it
