In actual fact, random distribution can be said to be the direct opposite of predictable spacing.

Weathering is a natural process by which the surface mineral of rocks is carried away by various agents .The agents can be water,wind,and ice. weathering means disintegration of rocks and the small parts are being carried away by these agents and are found on different places.Weathering of rocks depends on the many factors such as climatic conditions,type of rock,water availability and many more.The small rocks mix with soil and helps form sediment .This sedimentation helps to shape the earth's surface.This is an important part of rock cycle and is very important.
In 20 years, many of the country's 411 national parks, monuments and historic sites will suffer damage as sea levels rise, wildfires rage, glaciers melt and iconic wildlife, such as grizzly bears in Wyoming and pikas in Colorado's high-altitude tundra face shrinking habitat and scarce food.
Hope this helps you if I am wrong sorry
Have a great day!
The short answer is: The scientist means that a dose of 20 mg per kilogram is enough to kill one half or fity percent of the animals used in the test. LD stands for leathal doseage. The 50 means 50 percent. Subsequently a dose of 20 mg per killogram has a lethal dose that will kill 50% of the test subjects.
