Answer:
Marine debris can be harmful to coral reefs. Recycle your trash at home and on the go (especially plastic), and remember the three R's (reduce, reuse, and recycle). When disposing of trash, do it properly in bins, to avoid trash being blown or washed away into waterways and oceans.

Answer:
25 is the answer

Step by step solution for calculating 40 is 160 percent of what number
We already have our first value 40 and the second value 160. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
STEP 140 = 160% × Y
STEP 240 =
160
100
× Y
Multiplying both sides by 100 and dividing both sides of the equation by 160 we will arrive at:
STEP 3Y = 40 ×
100
160
STEP 4Y = 40 × 100 ÷ 160
STEP 5Y = 25
Finally, we have found the value of Y which is 25 and that is our answer.
You can easily calculate 40 is 160 percent of what number by using any regular calculator, simply enter 40 × 100 ÷ 160 and you will get your answer which is 25

i. Using fossil evidences
ii. Similar rock lithologies at the edges of continent
iii. Climate clues
iv. Fitting of the continents into a puzzle
v. Sea floor spreading
Explanation:
Pangea was a super-continent on the earth which formed about 330 million years ago during the Paleozoic and began breaking up during the early Mesozoic, about 175 million years ago.
Most of the present day continents formed as a result of the separation of the Pangea in the early Mesozoic.
The first scientist to propose the existence of this super-continent was Alfred Wegener in 1912. He suggested the continental drift hypothesis to explain the separation of the land masses.
Today, the theory has been revised to the theory of plate tectonics which provides a better mechanism to understand the drifting of the continents.
Here are some of the evidences to support the existence of Pangea;
- Using fossil evidences: Mesosaurus, a reptile animal that lived during the Permian, was found in both South America and Southern Africa. Since this animal could not swim nor fly, only a jointed landmass could have made them present in both continents.
- Similar rock lithologies at the edges of continents: rock formations at the Western edge of Africa and South - Eastern part of Brazil matches with one another and have been believed to be once joined together.
- Climatic clues such as glacial tills that are confined to temperate and polar regions have been found in tropical regions.
- Wegener fitted the present day continent into a giant supercontinent and this provided a visual support for his claim.
- Evidences from sea floor spreading revealing magnetic reversals at divergent margins suggests the prevalence of plate tectonics i.e moving plates on earth.
This among many other evidences underscores the existence of a supercontinent called Pangea.
Is this for the entire world or just The U.S.? If its the U.S. than its increased slightly.
Answer:
erosion affects not only economic development but climate changes, because the process of soil erosion releases carbonium ions into the air, while carbon dioxide is the primary cause of global warming
