Answer:Im not sure,but i think its called a raised beach,or a marine teracces
Antennas are transducers that convert radio-frequencies into alternating currents. The simplest kind of antenna is a length of wire, connected at one end to a transmitter or receiver.
Answer:
I think it might be the third one... but I'm not sure.
Explanation:
I think k represents gravity because it's the string keeping the ball attached to the pole.

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.
