Answer:
During the time of Pangaea most of the dry land on Earth was joined into one huch landmass that covered nearly a third of the planet's surface. The giant ocean that surrounded the continent is known as what?
Pangaea existed during what geological time periods, which were times of great change?
Most distributions of rocks within Earth's crust, including minerals, fossil fuels, and energy resources, are a direct result of the history of plate motions and collisions and the corresponding changes in the configurations of the continents and ocean basins. Research and explain how plate tectonics could account for these resources exactly.
North America has gradually grown in size over the past 4 billion years through a complex set of interactions with other continents, including the addition of many new crustal segments. What were these continents and what areas of the United States were created by new crustal segments exactly.
Well to start off on a graph the x goes left and right and the y goes up and down. you always read coordinates (x,y), so -4 needs to go left and make -6 and the 2 needs to go up making 4 so your new coordinates are (-6,4)

Answer:
a. three directions at ~90°
Explanation:
Galena is known for its presence in all types of rocks (igneous, metamorphic and sedimentary rocks). It is predominantly ore of lead which has a chemical configuration of PbS and lead sulfide. Also, newly severed chunks of galena display excellent cleavage in three directions at ninety degrees.
Hence, in this case, the correct answer is "galena’s cleavage is best described as three directions at ~90°"
