Which evidence originally supported Hess’s idea of seafloor spreading in 1968?
A) Younger rocks are closer to mid-ocean ridges.
B) The destruction of crust occurs at deep-sea trenches.
C) Oceanic rocks are pillow-shaped when formed.
D) Rocks across the ocean floor have alternating magnetic stripes.
Answer:
The evidence that originally supported Hess's idea of seafloor spreading was that the younger rocks are closer to mid-ocean ridges.
Explanation:
A is correct because Hess noticed that the rocks that are closer to the mid-ocean ridges are younger, and as their distance from the mid-ocean ridge increased, their age increased as well, thus giving him a clue that the seafloor is spreading.
B is not correct because Hess never managed to examine the deep-sea trenches.
C is not correct because Hess didn't have the means to be that close (in water) to a mid-ocean ridge where the new crust is formed so that he can witness it, and this was mainly due to the lack of proper equipment.
D is not correct because magnetic stripes indicate the positions of the poles throughout the geological past.

A

Answer:
Columbus was a horrible man that killed, enslaved, tortured and raped Natice Americans when they did nothing to him besides welcomed him onto their land with open arms. He forced his believes onto Native Americans and brought deadly diseases that killed the majority of the Native population. A day that is "celebrated" because he "found" America (although he didn't) despite the awful things he did would be upsetting knowing that person is the reason millions had died.

Explanation:
Using complete sentences, briefly describe what the image above represents. What are the main differences between the tierra caliente level and the tierra fria level?
The image represents the various classification of Earth's environment based on the altitude. To each zone correspond a certain type of climate, where certain types of plants for example can or cannot grow. That's called "Altitudinal zonation". Basically, the higher you go, the colder it gets. That's especially useful to describe the climate in tropical but mountainous regions, like Latin America.
Difference between tierra caliente and tierra fria:
Tierra caliente (warm land) level is the lowest and goes from sea level up to 2,000 or 3,000 feet depending on who you ask, and it's the perfect for fruits and most livestock for example.
Tierra fria (cold land) level starts at 6,000 feet. It's a zone where virtually no livestock can be found and only robust vegetables (like potatoes) can grow easily.
The main differences are of course their altitude but also, as a consequence of the altitude, the types of plants that can grow in each level, which are extremely different.

Explanation:
Describe how the sea erodes the coast (3 marks)
Answer:
There are three main ways in which the coast can be eroded by the sea:
Hydraulic action: lots of sea water crashes against the land, causing air and water to become trapped and compressed in surface cracks. When the sea retreats the air expands, weakening the cracks in the rock and causing pieces of the rock to break off.
Corrasion: caused by bits of rock hitting the cliffs and other parts of the land, causing more bits of rock to break off.
Corrosion: involves the chemical action of sea on rock, often happens with limestone beaches, when the limestone dissolves in the sea water although the salt can affect some other stones as well.
Explanation:
Answer:
Waves can erode the coastline in a similar way to the water in rivers. This usually occurs when the sea takes lots of energy from the power of destructive waves. Transportation - the movement of eroded material up and down, and along the coast.
