Biological weathering is caused by living organisms, such as microbes, animals, and plants. Water, oxygen, and rocks are nonliving things (though water and rocks may be capable of weathering), and only plant roots fits the definition of biological weathering. So the correct answer for #1 is A.
Frost wedging occurs when the little water content in rock freezes, expanding and forcing the rock apart. Eventually, enough freeze-melt cycles causes the rock to break apart little by little. This is due to ice's density being less than that of water, meaning that it is because water expands when frozen. So the answer to #2 is A.
Answer and Explanation:
"Blocked opportunity" is the term that defines the state when a particular person is not able to achieve the desired goal due to the society or any other factor. The opportunity that the person is waiting for or had high hopes with goes away from the hand , this situation leaves the person in the state of sadness or depression.
This state also leads to stain the person and his thoughts. The situation of strain and delinquency sometime lead to criminal tendencies as well according to many theories. Crime causing act is performed towards the society because the person starts to blame society element behind the failure of not achieving the goal and unsuccessful.
Answer:
every earthquake is recorded on numerous seismographs located in different directions. Knowing this helps them calculate the distance from the epicenter to each seismographs. To determine the direction each wave traveled, scientist draw circles around the seismographs locations
Most fo the hurricanes that affect the east coast of the United States originally form over the warm waters of the Atlantic Ocean in Summer (1). The warm waters of the Gulf Stream run along the east coast of the United States. This provides an environment which is conducive to the development of hurricanes. The basics of the formation of a hurricane are as follows. Winds start blowing in a circular motion. This causes hot, moist air to rise. Clouds are formed and the winds start blowing faster and faster. This forms a low-pressure zone. The surrounding high-pressure zones pull the hurricane towards them. As the hurricane moves, it either picks up speed or decreases its speed and intensity.
Answer for first picture:
#1 = 43 degrees #2= 38 degrees
#3= 27 degrees #4= 45 degrees
Explanation for first picture:
All the angles are right angles. This means they all will equal 90 degrees! so if you take 90 degrees and subtract the one known angle you will have your answer! :)
Answer for 2nd picture:
#1 = X= 70 Y= 110
#2 = X= 102 Z= 102
#3 = X= 83 Y= 194
#4 = Y= 37 Z= 143
Explanation for second picture:
When you have angles like these the total will equal 360 degrees! look at the first pic, it shows 110 degrees, you also know that the angle across of it is equal to it. so together it equals 220 now subtract 360 - 220. you get 140. since you have two angles to figure out, you divide 140 into two. 140 / 2 = 70 degrees! you do the same steps for the rest of the problems!
