Answer:
Convergent and divergent plate boundaries
Explanation:
In a convergent plate boundary, two plates move towards each other. Due to the impact, the heavier tectonic plate subducts beneath the lighter plate. This results in the formation of a subduction zone, and there forms a trench above this zone. The rocks at greater depths, melts and mixes up with the magma and eventually rises upward, towards the surface in the over-riding plate, giving rise to the formation of volcanoes and volcanic arcs.
In a divergent plate boundary, two plates move away from one another. Due to this opposite motion of plates, there occur cracks on the seafloor and land areas, from where the magma comes out. With continuous spreading, there forms a ridge, which is commonly known as the mid-oceanic ridge. This type of plate boundary is responsible for the formation and expansion of the ocean basin. For example, the mid-Atlantic ridge.
Answer:
<u>Time is measured in Lunar month </u>
Explanation:
- The lunar month is the time the moon takes to pass through each phase i.e new moon to half and then to the full moon etc. Taking about 29 days, 12 hours, 44 minutes and 3 seconds to complete this rotation on its axis.
- Thus the moon only takes 27.3 days to complete this action. Thus as the moon goes back in its orbit it takes 2.2 days to catch up. Moon also has the same elliptical longitude as that of the sun as seen from the earth's surface.
- The motion of the moon is in an eastward direction along with the motion of stars, thus it shows the same face to earth every day. This is evident as it moves just 13 degrees in 24 hours.
The contrapositive of the conditional statement is option d: If the graph of two variables is not a linear function, then the two variables are not directly proportional.
<h3>What is the statement about?</h3>
To known a statement that is contrapositive, you will need to negate the hypothesis as well as the conclusion of the statement, and also switch their positions.
Hence:
- If two variables are directly proportional, so their graph is a linear function.
- If two variables are not directly proportional, so their graph is not a linear function.
Therefore, The contrapositive of the conditional statement is option d: If the graph of two variables is not a linear function, then the two variables are not directly proportional.
