Answer:
Compression squeezes rocks together, causing rocks to fold or fracture (break) (figure 1). ... Rocks under tension lengthen or break apart. Tension is the major type of stress at divergent plate boundaries. When forces are parallel but moving in opposite directions, the stress is called shear
Explanation:
Answer:
Explanation:
A - this is true because if you look at how long each line is for Italy compared to Somalia, it's longer
D - if you look at the longest line for Somalia - it's the longest line for Somalia so I believe this is the right answer
Answer:
None of these answers, that I know of, remove carbon dioxide from the air, photosynthesis how ever does in fact do that.
Explanation:
Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2.
Answer:
(C) ocean floor
Explanation:
The protolith or parent rocks that forms schists are basically mudstones and shales. These are clastic sedimentary rocks that are rich in fines(clay sized particles).
Most shales are usually formed in deep ocean floors because larger sized clastic sediments cannot reach these environments. Winds and waves acts as active agents to deposit fines on the ocean floor.
Since shales are predominantly made up of clay minerals which are products of micas that have been chemically altered, we expect these clay minerals which are hydrous(contains water) to revert back to mica under metamorphic conditions.
As metamorphic transformation progresses under intense pressure and temperature and also minerological transformation, our rock moves from slate, to phllylite and then to schists.
Slate is a low grade metamorphic rock that is usually fine grained and foliated. As metamorphism increases, mica begins to grow and a shiny lustre appears in the rock, a phyllite results. Schists have larger mica grains and are foliated also.
Desert dunes are mostly made of sandstones. Their metamorphic transformation yields quartzite.
Coral reefs ar made up of rich calcite deposits and would form a metamorphic rock known as marble.
