How can a scientist see the details of the moon?
We see the moon because the moon goes in front of the sun so the sun reflects on to the moon when that happens the moon makes a shadow over a bite of the Earth
How do scientists know dinosaurs existed?
1. There is an unusually high concentration of Iridium found at the K-T boundary. Iridium loves to stick to Iron, so the Iridium that would have been on Earth originally is in the Iron core, not in the crust. Therefore, the Iridium must have been introduced by an external source; a meteorite.
2. Shocked Quartz is found at the K-T Boundary all around North America. Shocked Quartz is only produced naturally by bolide impact. Since the K-T meteorite impacted in the Mexican peninsula, it makes sense that the shocked quartz would be found only in relatively close proximity to the impact site.
3. Microtektites, which are normally found at meteorite impact sites, are found at all K-T boundary impact sites.
4. There is a massive impact crater in the Mexican peninsula.
5. In many of the K-T Boundary sections there is a fine layer of ash (disseminated Carbon) from the global wildfires that were caused.
6. There was a fern spike because other flowering plants stopped producing pollen for awhile.
7. Microdiamonds have been detected at K-T Boundary sites, but not above or below.
the first person to suggest the idea of atoms in the 4th century B.C.
--ANSWER-- He was a Greek philosopher who lived sometime between 460 and 370 B.C.
He developed the idea which his teacher Leucippus had that explained natural phenomena in terms of the arrangement and reargangement of atoms moving in a vacuum.

What do you call a scientists who studies snakes?
Ophiology is the study of snakes whereas Herpetology is the study of snakes and many other reptiles
The unit scientist use what to express force?
The unit of force is the 'newton'.
1 Newton = 1 kilogram-meter per second2
How do scientists study trees and plants?
i need to ask that question too, im stuck here with my homework
' write a simple method for photosynthesis'
and im like,
'what?!'
i dont pay attention is lessons (this answer sucks dude)
real answer:
CO2 + H2O + light energy --- (CH2O) + O2
What organ did Louis pasteurs stroke destroy?
I am looking too...
I will tell you if i find out!
-That guy who has homework problems
Well, I am looking too, I'll put the answer up tomarrow, when the answer is revealed at school! Please let me know if u have "Science and Life issues Student sheet 12.4" as your homework!
What is Dr Michio Kaku famous for?
His largest contribution is co-founding String field theory, which is a variation of String theory.
scientific consensus. It is reached when multiple scientists independently make the same observation and draw similar conclusions based on their research and data. This consensus helps to solidify our understanding of a particular topic within the scientific community.
What are two ideas about evolution that were proposed by scientists in the 18th century?
One was Darwin's theory was the process of evolution by natural selection and the second one was Lyell's theory was that animals can adapt and change their traits to fit the environment.
What 2 criteria do scientists use to classify living things?
There are 5 standard qualifications for living things:1) Grow and change2) Reproduce3) Energy absorption and use (i.e. eat, photosynthesis)4) Capable of death5) Organic
What is the Contribution of ernest Rutherford to science?
Ernest Rutherford contributed to the understanding of the atom. He used J.J Thomsons model and conducted a expirements in which he shot positively charged particles throught a thin gold foil. He predicted that all the high speed particles would pass straight through the foil without being affected by the gold atoms. Instead, the results showed that while most particles did behave as predicted, some were greatly deflected.
idk the answer so yeah
Standard use of measurement used by scientist?
There are 7 SI units (Systeme International d'Units) from which all other measurements are derived. These are: Length (metre) Mass (kilogram) Time (second) Temperature Interval (Kelvin) Electric Current (ampere) Amount of Substance (mole) Luminous Intensity (caldela) All other units aere derived from combinations of these 7 base units
What do you call a scientist who studies bears?
A scientist that studies bears would be called an ursinologist.
Scientist use what to obtain data from a hostile environment?
They would use instruments that were created for working with that environment. This is similar to the bomb squad using robots to get a closer visual of the explosives so they can figure out the best way to defuse them.
In 1668, Italian physician Francesco Redi first performed tests with rotting meat that showed that maggots did not form spontaneously as was previously thought. It suggested that living things could only be formed from living things of the same type.
Louis Pasteur in 1861 improved upon the experiments of John Needham, who in 1745 had suggested that living things could form despite sterilization of the medium. Pasteur boiled solutions in beakers that had necks shaped like an S, so that airborne microorganisms could not reach the solution past the neck. Mold did not appear in the unexposed liquid that was boiled, but did in the solution that was exposed to bacteria from the air.
What work is dr Samuel rawlins famous for?
Hopefully this helps you!
Casual observation over the past decade would have indicated that climate patterns have been indeed changing so this should not be at all surprising. One of the harsh manifestations of that has been more frequent hurricanes and tropical storms, increased rainfall and severe flooding events of hitherto unforeseen proportions.
The rainy season too has seemingly gotten longer, so much so that November 30 no longer marks the end of the Atlantic Hurricane season for a region wary about the potential for infrastructural collapse if guards are let down and the oddest of Hurricanes happens to strike in December.
Regardless, all of the scientific pointers lead straight to Climate Change. The globe is simply warming too fast! And humans are the cause of this. The simple truth is that even a one degree increase in temperatures in the Caribbean can wreak havoc. Thus, "(we) need to reduce our emissions of greenhouse gases," Dr. Samuel Rawlins, Professor Emeritus at the Caribbean Research and Epidemiology Centre (CAREC) told the Trinidad Express.
There may be a debate as regards the extent of Global Warming, but there can be no issue with the simple fact the earth's atmosphere is being filled up with carbon emissions that are destroying the ozone layer and subjecting mankind to heat waves that are taking lives and rising sea levels that threaten to reclaim low-lying lands, even entire islands. As these things to come to pass, the tourism product of already vulnerable Third World economies are being adversely affected.
Dr. Samuel Rawlins, was one of a group of renowned scientists who has been working towards a consensus understanding of the phenomenon of climate change. Dr. Rawlins and University of the West Indies (UWI) professor John Agard were co-opted by senior climate scientist Dr. Roger Pulwarty who with two other Caribbean scientists contributed to the 2007 report of the United Nations' Inter-governmental Panel on Climate Change (IPCC) that helped the institution win a Nobel Peace Prize. That prize was shared in December with former United States Vice President Al Gore, one of the world's leading advocates for environmental reforms to stem the tide of global warming.
"To me, the (Nobel) prize means that the issue of climate change has gotten more of the public focus and more people are aware that climate change is taking place and that all of us can do something to stop it," Dr. Rawlins told the Express in a phone interview on Tuesday, October 16, 2007.
Dr. Rawlins, a Kittitian, who is recently retired as the Director of the Caribbean Epidemiology Centre (CAREC) in Trinidad after a 20-year career, is a specialist in the study of insect vectors of disease. Thus, his contribution to the UN report, which was two years in the making, focused on public health issues associated with climate change. "Climate change affects us all in a very real way. The Caribbean countries are more vulnerable than larger countries, and if we don't move very quickly to undo the damage that is being done it will affect the coming generations of our people," he said.
For those persons who doubt the effect of climate change on vector proliferation and disease transmission, Dr. Rawlins offers up a recent study on climate change in the Caribbean. That study demonstrated that even climate variations, that is less severe manifestations of a climate change, have increased the prevalence of not only Dengue Fever and Malaria, but probably other vector-borne diseases as well. "The UN has already recognised that 150,000 people die each year due to the effects of climate change," Rawlins said.

Anthropology examines human aspects of past cultures such as traditions and social habits. They study humans in the past and present.
What do scientists do to determine if their results support their hypothesis?
The results can support their hypothesis by comparing the results, or setting them out in a table or graph. Conclusions can also be written to simplify the process.
