1. what is pushing apart north america and eurasia?

1. why are there so many earthquakes in california?

1. what type of rock are continental plates made from?

1. what type of rock are oceanic plates made from?

1. which type of plate is most dense: oceanic or continental?

1. if an oceanic plate and a continent plate converge, or push towards each other, which plate will sink under the other one?

32 what landform is created when two continental plates push together at a convergent boundary?

1. what occurs when two continental plates move away from each other at a divergent boundary?

Explanation:

1. The west - coast of the US has a transform boundary (the San Andreas Fault) where the Pacific Plate and the North American Plate slide past each other.
2. Observation could be about the complexity of plate interactions or the variety of boundaries.
3. The largest tectonic plate is the Pacific Plate; the smallest could be the Juan de Fuca Plate among well - known ones.
4. Time will vary depending on individual play.
5. Mid - Atlantic Ridge spreading is pushing North America and Eurasia apart due to the upwelling of magma and seafloor spreading.
6. California has many earthquakes because it is on a transform boundary (San Andreas Fault) where plates are constantly moving and building stress.
7. Continental plates are made of granite - rich rock (felsic rock).
8. Oceanic plates are made of basalt - rich rock (mafic rock).
9. Oceanic plates are more dense than continental plates.
10. The oceanic plate will sink under the continental plate during convergence due to its higher density.
11. When two continental plates converge, mountain ranges like the Himalayas are formed.
12. When two continental plates diverge, rift valleys are formed.

Answer:

1. Transform boundary
2. Varies (e.g., Plate interactions are complex)
3. Largest: Pacific Plate; Smallest: Juan de Fuca Plate (among well - known ones)
4. Varies
5. Mid - Atlantic Ridge spreading
6. It is on a transform boundary (San Andreas Fault)
7. Granite - rich (felsic) rock
8. Basalt - rich (mafic) rock
9. Oceanic plate
10. Oceanic plate
11. Mountain ranges
12. Rift valleys
