<em><u>Answer:</u></em>
144 degrees
27 degrees
<em><u>Explanation:</u></em>
f) So angle EBD is angle 5, which is 36 degrees. Angle DBC is angle 1 and is 108 degrees. We need to find angle EBC or 5 + 1.
So we know that EBC is angle 5 + 1, we can do angle 5 plus angle 1 or:
36 degrees + 108 degrees = 144 degrees.
Angle EBC is 144 degrees.
g) So we know angle EBF or angle 4 + 3 is 117 degrees. We need to find angle ABE or angle 4. We know that angle 3 is 90 degrees because of BF is perpendicular to AC. So now we can find angle ABE or 4:
117 degrees minus 90 degrees = 27 degrees
Angle ABE is 27 degrees.
Earths history of climate is easily understandable through the study of existing rock and shells aquatic organisms. Rocks came into the earth million of years ago. So, the study of age determinism of rock gives an idea of climate through which it has come across. This is called paleontology.
Explanation:
In studying Earth's history of climate scientists take help of available rocks and body parts of aquatic animals. As rocks are the most eventful findings on the earth's surface which has come across million of years and witnessed several changes. These study if changes in rock is called paleontology.
Shells of aquatic animal which found in underwater are also a good evidence of earth's history of climate. It is found in the layers of sedimentary rock which is soft in nature and found in layerwise. Where all the organism became fossil after death and its body parts remains in the form of stone.
Answer:
climate change threatens coastal areas which are already stressed by human activity pollution invasive species and storms sea level rise could be rolled and in coastal ecosystems and eliminate Wetlands warmer and more acidic oceans are likely to disrupt Coastal and marine ecosystems
Answer:
China is a very large country that has border with 14 countries. However, in this case only the Chinese landforms that serve as borders will be listed:
-The Himalayan mountain range in western China that serves as a border with Nepal.
-The Gobi desert, at the north of China which is the border with Mongolia.
-The Tibetan plateau in western China that borders on India, Bhutan and Nepal.
-The Manchurian plain to the northeast of China, is the largest plain of the country that borders North Korea.
Answer:
C. Tension due to cooling of flow,
Explanation:
- These joints on the basaltic rocks through occurring in moistly igneous rock types, created by lava and ash flow. Some Of the famous Columnar joints are found in places like Devil tower, Giant Causeway, and Deccan Traps, etc.
- Upon cooling these forms These are arranged in regular angles and straight columns.
- And the irregular array is termed as entablature. These condense to form various forms in nature through the cooling and spreading of lavas.
