Sam bought a new car seven years ago today - absolute age
Sarah s company was formed a few years after James’s company - relative age
Luke’s school was built in December, 100 years ago. - relative age
Alice’s school is older than Luke’s school - relative age
Louisa owned a car long before Sam - relative age
James’ company has been in existence since 1991 - absolute age
relative age - the age of an event is determined in relation with another event (or another person)
Absolute age - the age of an event is a fixed moment in time, which can be traced back with precision and does not depend on another event, person or age
The main purpose of a dike is protecting the land behind it from flooding.
Answer:
C. When the oceanic lithosphere, which is more dense, sinks and pulls the plate with it
Explanation:
Slab pull and other mechanisms are responsible for the motion of plates. Every tectonic plate is driven by mantle convection.
- Convection is a form of heat transfer in fluids.
- It is as a result of differences in density and temperature values.
- The oceanic crust is denser and colder.
- As hot magma from deep within the subsurface rises and move through cracks, the oceanic lithosphere is drawn down and deeper.
- This cycling between the cold lithosphere and hot rising plumes provides the mechanism that drives plate motion.
The correct answer is - True.
The transform boundaries of the tectonic plates are boundaries where two tectonic plates are sliding against each other. As they do that, they do create geological activity around the boundary, and earthquakes are a common occurrence. Another trademark of these boundaries are the faults, that stretch for several km in a linear manner, usually parallel to the boundary itself. Most of these faults are located in the ocean basins and they are connecting the offsets of the mid-ocean ridges, but they can also be found on land, like it is the case in California.
