The answer is below
Explanation:
Dear Dad,
I've really missed you, Dad. How's Mum and everyone at home? I'm sure kitty cat is still kicking? How about the PSP you promised to buy for me? I hope you've bought it already? I can't wait to come home and meet you all.
Dad, soon enough, we'll be having Mid-term online Examinations and this will be my first time taking such an exam, hence, I need every good tip I can get to pass.
Since you're an examiner, I believe you can easily tutor me on this.
What are the things I should be aware of? How can I ace my exams without overstressing myself? Is there a specific method in reading for this type of exam? Please reply quickly and add many more tips that can help me succeed.
Thanks, Dad, I love you.
Yours sincerely,
Billy
Answer:
concrete
Explanation:
Researchers think regolith on Mars could serve as a replacement for concrete components. The Mars rovers have used gas chromatography, mass spectrometry, and laser spectrometry to determine the composition of martian soil. Mars regolith is mostly silicon dioxide and ferric oxide, with a fair amount of aluminum oxide, calcium oxide, and sulfur oxide. The composition varies from place to place on the planet’s surface because of variability in asteroid collisions and the weathering by wind and water, in ancient oceans and in some modern water flows. But no spacecraft has returned to Earth with actual samples of the material.
