Infrared radiation is invisible to the human eyes, but we can feel it as heat.
Geologists have recently determined that the minerals goethite and hematite exist in abundance on Mars, sure signs of the presence of water (see Figure 1 for a picture). None of those geologists have been to Mars, of course, but the unmanned rovers Spirit and Opportunity have. These rovers are equipped with three mass spectrometers, each of which is capable of determining the chemical composition of a solid with a high degree of accuracy. With such a precise chemical analysis in hand, geologists on Earth had no problem identifying the minerals.
A mineral is defined in part by a specific chemical composition. In theory, therefore, it is always easy to identify a mineral, if you can determine the chemical composition with a mass spectrometer like the Mars rovers. In reality, however, even if you are looking at rocks on Earth, determining the exact chemical composition of a substance involves significant time preparing the sample and sophisticated laboratory equipment (and often significant money). Luckily, it is usually unnecessary to go to such lengths, because there are much easier ways that require little more than a magnifying lens and a penknife.
Answer:
Ang pagbabago ng klima ay may malaking epekto sa iba't ibang mga panlipunang aspeto ng buhay.
Explanation:
Ang pagbabago ng klima ay may malaking epekto sa iba't ibang mga panlipunang aspeto ng buhay. Ang mga damit na isusuot namin nang direkta ay nakasalalay sa klima ng aming rehiyon. Habang nagbabago ang klima ng rehiyon ng rehiyon, nagbabago rin ang kagustuhan ng suot na damit. Habang nangyayari ang pagbabago ng klima sa mundo, tumaas ang pandaigdigang temperatura at ang mga sosyal na aspeto ng buhay ay nagbabago din sa pagbabagong ito ng klima. Maraming mga tao na hindi magparaya sa pagtaas ng temperatura na lumipat sa mga cool na lugar at pagbabago ay nangyayari sa kanilang mga panlipunang aspeto ng buhay tulad ng wika at kaugalian atbp.
weather is per day and climate is over 30 years
Answer:
Neither country wanted to engage in a nuclear war that would lead to worldwide destruction.
Explanation:
The US and USSR became arch enemies soon after World War II ended, and that continued to be the case until the USSR seized to exist. The two countries became opponents and developed very bad and tense relations because they had different ideas as to how the world should shape up, but also because both of them wanted to be the only dominant power in the world.
Both countries were heavily armed and the weaponry was constantly icnreasing, with newer and better weapons constantly been created to gain an advantage. Nuclear weapons were abundant at both as well, but they never got used in an open war between them. The reason was simple, if a direct war between them occurred, there would have been worldwide destruction and everyone will lose, so that was kept as the last option in case of an attack by the other. Not to be mistaken though, these two were constantly in war with each other, not just diplomatic, but also military one, just that they used other countries as battlefields where they supported a particular side.
