<h2>Answer: seismograph
</h2>
A seismograph is an instrument that was invented by the scottish physicist James David Forbes in 1842, with the purpose of measuring the movements of Earth's tectonic plates, which cause earthquakes.
The original design of this instrument is based on the principle of inertia (all the bodies have a resistance to movement or to vary their speed); and consisted of a pendulum that remained immobile (due to inertia) during an earthquake while at the end it had a punch that moved along with the ground shake and then recorded all the movements on paper.
However, at present, seismographs have improvements in their functions and it is also possible to determine the epicenter of the earthquake.
The answer is A. Cartographers employed into the government can help with national defense.
The resulting imbalance between incoming solar radiation and outgoing thermal radiation will likely cause Earth to heat up over the next century, accelerating the melting polar ice caps, causing sea levels to rise and increasing the probability of more violent global weather patterns.
I think the answer is B. Hope this helps.
Answer:
Based on the solar light that enters the oceans and river
Explanation:
- River ecosystem of a couple of both biotic and abiotic components among the plants and animals involving there physical and chemical properties. As the flow of water is unidirectional, it's in state of continuous physical change and has a high degree of spatial and temporal heterogeneity.
- River sources are small, and in the areas of mountain streams, are steep and erosional. In temperate environments, overhead tree canopy conditions result in cool, well-oxygenated streams.
- All sorts of communities like coastal, estuaries, reefs and deep-sea trenches like Mariana trench which has no sunlight has a distinct type of community.
