Answer:

When plates move away from each other, the space between them gets filled with material, which rises to the surface, cools and forms mid-oceanic ridges. The Pacific Ocean is growing wider by about 18 cm per year as the plates diverge and the mid-oceanic ridge is built up. Where plates come into contact, energy is released. Plates sliding past each other cause friction and heat. Subducting plates melt into the mantle, and diverging plates create new crust material. Subducting plates, where one tectonic plate is being driven under another, are associated with volcanoes and earthquakes.  

When Alfred Wegener first proposed the idea of continental drift (the precursor idea to plate tectonic theory), it didn’t quite explain the full story. While he correctly showed that Africa and South America fitted together, his model wasn’t able to explain the violent forces that occur around the Earth’s crust. It wasn’t until the 1960s that a full explanation began to develop – the theory of plate tectonics.

Angelina_Jolie [31]

Answer: During the day, valley air heats rapidly and rises upslope. At night, mountain air cools quicker and moves downslope into the valley.

Explanation:

The correct statement about Mountain-Valley breezes is that during the day, the valley air heats rapidly and then rises upslope while at night, mountain air cools quicker and then moves downslope into the valley.

During the day, when the valley floor warms, it should be noted that the warm air will then rise up to the slopes of the mountains that are around its surrounding which brings about a valley breeze.

Then during the night, the denser cool air will then slides downward the slopes and then settle in the valley which then gives the mountain breeze.

Therefore, the correct option is A.
