GPS is a new tool in geography that can help us find locations. GPS stands for Global Positioning System.
<u>Explanation:</u>
GPS stands for The Global Positioning System. It is a network that has about 30 satellites that orbits the Earth. These are at the height of about 20,000 km above the earth. This was initiated by the government of United states for the purpose of navigation of military. Now a days GPS can be used by anyone using a GPS device and can be able to receive the signals that are broadcasted.
There will be at least four GPS satellites that will be visible over any time. The information will be transmitted at a regular interval of time depending upon the position and the current timings. These signals will be transmitted at the speed of light and will be identified by the GPS receiver.

Answer:
que estuda os astros são os astronomos
Explanation:
Answer:
Mercury has the shortest rotation, because it is the closest to the sun, and as such it makes a smaller circle of orbit around it.

Answer: Choice (4) in the bottom right corner</h3>
===========================================================
Explanation:
The sun warms up the land and the air adjacent to the land. The earth/rocks aren't a very good heatsink compared to the water, so effectively the heat energy bounces off the land and into the air. The land-adjacent air is heated much quicker compared to the water-adjacent air. The warm air over the land rises because the air particles are more energetic to bounce around faster. The rising warm air spreads out not only vertically but also horizontally as the diagram shows.
As the warm air moves over the colder lake, the warm air cools down and sinks. The breeze from the lake moves toward the land, due to the pressure difference (wind moves from high pressure to low pressure), and this starts the process all over again.
All of this describes diagram (4) which is the final answer. This diagram is a very simplified view and actual weather patterns are much more complicated.
-------------------
Side notes:
- Choice (1) can be ruled out because the surface wind should flow from the water toward the land. Also, the lake acts like a heat sink, so not much heat energy will cause warm air to rise compared to air on the land (which isn't that great a heat sink).
- Choice (2) can be ruled out because warm air should rise, and not sink.
- Choice (3) can be ruled out because cool air doesn't rise.
Answer:
First, precipitation dissolves chemicals in the atmosphere and this solution causes chemical reactions on the various surfaces it falls on thereby weakening those surfaces through this action. Second, the force of the water onto the Earth's surface gradually wears it away
