Answer:
Position 4
Explanation:
Position 1 and 3 are easily identifiable as Summer and Winter as the Americas are are facing directly at and away from the sun. Position 2 is Spring as North America is getting more sunlight that position 4, leaving position 4 to be autumn/fall
Hope you can follow that mess of logic :/
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.
Continental Polar and Maritime Polar ; Polar had a direct connotation with the cold. :)
The third one the second one and the first one
It is estimated that 100 million animals die every year due to water pollution.
In addition, ocean pollution affects 1,000 species of marine animals. However, these are rough estimates because it is almost impossible to calculate the exact number of animals killed by water pollution. Polluted water can pose a serious threat to both animals and humans. Animals and plants living in this water often die from this pollution.
Even if a particular animal did not die from pollution, it would likely die from changes in the food chain. Animals and people who drink water from this source can contract bacteria and diseases that are often carried in this water.
