Temperature and density increases from the crust to the core.
The correct answer is C. There is a large amount of rain or snow in the air.
Explanation
According to the fragment of the question that states that "To use a radar, a weather tower sends out radio waves and then detects the waves that are reflected back to the tower" it is possible to infer that the radar waves that are reflected towards the tower They are the product of the collision of these waves with an object that is in the air such as rain. Therefore, in the case in which a large number of radio waves are reflected towards the tower in a particular area, it can be said that this is due to a large number of objects in the air in this area such as rain or snow. So the correct answer is C. There is a large amount of rain or snow in the air.
Currents involve movement of ocean water masses, driven either by wind or by differences in temperature, salinity and density. The most important from a human perspective are the wind-driven surface currents that move water in the uppermost layer of the ocean.
Currents affect humans in several primary ways. Currents help shape the climate in the areas where we live, create the right conditions to support abundant ocean life in the areas where we fish, and change weather patterns through periodic events like El Nino/La Nina.
Ocean currents also cause upwelling in many areas like off in the inland parts of North America, where surface currents taking water away from the shore cause nutrient-rich water to well up from the ocean deeps. The abundance of nutrients in these areas forms fertile ground for kelp beds and marine fisheries, which in turn furnish food for humans. Alterations in current patterns like the El Nino/La Nina cycle affect humans as well by causing changes in local weather patterns in the years when they occur.
