Answers
Explanation:
1 Exosphere
2 Verbal scale
3 Geologists have used two main types of evidence to learn about Earth's interior: direct evidence from rock samples and indirect evidence from seismic waves. The geologists in Figure 2 are observing rock on Earth's surface.
4The object blocks some of the sunlight and causes the shadow. ... If the Sun's rays are incident on an object, the shadow is oriented away from the Sun. The shadow length changes through the course of a day as well as through the year, for example, a noon shadow is much shorter in summer than in winter.
5A new clock in a modest lab at the National Institute of Standards and Technology in Boulder, Colorado, currently claims the title of world's most accurate device.
