Aa is lava that forms a thick ,brittle crust . Pahoehoe is a lava that
forms a thin crust. Pillow lava forms when lava erupts underwater.
Blocky lava is kool, stiff lava that does not travel far from thr
eruption site.
Answer:
secondary succession
Explanation:
In the described scenario we have a destruction of an ecosystem because of natural causes, volcano in this case. All that has left after the volcanic eruption has been barren land. After this has happened life started colonizing the volcanic island again, in a process known as primary succession. In the primary succession it is the organisms that have the lowest of requirements for survival that will inhabit the island. Over time, as they die, they will provide biomass for the ground, thus soil will start to form. Once there's soil formed a process called secondary succession will start. In this process the island will start to be inhabited by some plants and smaller animals. These plants and animals will contribute to further enhancing the living conditions on the island, and the island will gradually be getting larger plants and larger animals, thus a new ecosystem will be formed on the place of the old one.
All quadrilaterals are alike because all of them have four sides, are coplanar, have two diagonals, and the sum of their four interior angles equals 360 degrees. Quadrilaterals can be different because they may or may not have parallel sides or equal sides, and there are many different types of quadrilaterals with special properties.
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!
