Explanation:
1. Oxygen, without oxygen no human can live, In space, there Is zero oxygen
2. Water, Astronauts will definitely need some sort of water since nearly every living thing requires It
Answer:
PUT THIS IN YOUR OWN WORDS SO YOU DON'T GET COPYRIGHTED
Mr/Mrs.logger, in this letter I would like to persuade you to stop cutting down trees. It will help the economy, you can find a new job, and you will understand that being greedy is not okay. Keep reading on to understand why. Thank you!
Cutting down trees in this state is illegal. I understand you are trying to help your family by making money. But, there are many other ways to do so like, helping people build fences, go to a store and be a cashier, help people move things, etc. Finding another job could help you put food on your family's table and not send you to jail.
If that didn't persuade you to look at the Amazon Rainforest for refrence, people took down those trees to help support their family but it only ended up destroying another family's home. All of these creatures lost their homes that they had to keep their family safe, warm, alive. But, all those loggers did was put these animals on the brink of extinction just to help their own families. And, the Amazon Rainforest is very important and needed in this world. It is one of the many reasons that earth is habitable, it's water cycle's, the many tree's giving off Co2, it is also home to 30 million people! and over 10% of the world's biodiversity! That's a lot. And, the tree's that you are cutting down could someday be a rainforest that will contain millions of people. So really think about it, think about what you are doing to the world, think about how you can fix it.
So I hope that I was able to persuade you to learn to do something else that won't ruin or economy, I mean we all mess up with something that will make our Co2 footprint bigger but there are many ways to try and fix that like tyring to make a compost garden, plant a garden, do anything that will help your family and the animals/plants surrounding you.
Answer:
D) the steady, clocklike decay of certain radioactive isotopes over time.
Explanation:
Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.
For example, when rocks are formed, such as igneous rocks (formed when molten rocks cools), certain radioactive atoms are trapped inside the rocks during this formation process. Then these radioactive atoms decay over time.
The age of the rock can be estimated by comparing the occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
From the options;
A) this is about the formation of the radioactive molecules and not about radiometric dating
B) this is radiocarbon dating (cabon dating/carbon-14 dating)
C) the <em>assumption </em>is wrong since the radioactive isotopes decays not accumulate.
D) the corect option as I explained earlier.
It is a sphere but not a perfect sphere. There a ton of trees in the way xD. Have a feeling this is a trick question....xD
