One reason is that the plates float on a hot boiling mentle. when the heat rises and the mentle expands the plates above it also moves.
the other reason is that the plates themselves move.plates have warmer inner sides that tend to rise. and colder outer side that tends to sink. this tug of war between the hotter and colder sides of the plate also helps them move.
Answer:
The day moon is a product of the sunlight reflected on the satellite. Sometimes, we can see the moon during the daytime, because depending on the moon´s position, sunlight is reflected on the satellite, allowing us to see from the Earth during the day.
Explanation:
The moon is a dull satellite that has no light by itself. The only way we can see it is through the reflection of the sunlight on this body. This effect also depends on the moon´s position concerning the Earth and to the sun. It is a natural product of the rotation and translation movement of the Earth and the moon.
This effect is related to the moon phases: new, first quarter, full and third quarter. During the daytime, we can see the waxing and waning gibbous phases because the moon is placed in a way that sunlight reaches it and reflects its shape. When this effect occurs, we can see that the star and the satellite get more separated each day. The moon gets to hide in the skyline later than the sun. This is why sometimes we can see the moon during the evening or the day.
Answer:
d. Some magma generated during seafloor spreading spills out to produce a new layer of seafloor called gabbro.
Explanation:
- The magma is spilled from the mid-oceanic ridges and spreads onto the seafloor creating a newer seafloor.
- This is why it's called as the divergent boundary due to the spreading of magma on both sides of the floor. Grabbo is a coarse-grained mafic intrusive igneous rock and is formed at the oceanic ridges.
