The main reason why the tectonic plates move is the conversational currents. There is magma between the upper mantle and the asthenosphere that heats up at the upper mantle. The weight is so small that the magma rises with the help of these conversational currents. When the magma has ascended towards the asthenosphere, it has nowhere to go so the magma lies along the asthenosphere. There the magma cools down again because the asthenosphere is colder than the upper mantle, which makes the magma heavier and goes back down to the upper mantle, where the magma heats up again and everything starts all over again and so it goes on over and over again. Scientists have concluded that the earth's gravity causes two other processes that also cause the tectonic plates to move.
Ridge push - in the spreading zones, the sides of the tiles are raised and slide to the side as in a slide.
Slab pull - when a plate is pulled down by gravity in a subduction zone like an anchor.
Weathering and erosion
Explanation:
Weathering and erosion are the processes that would be partially responsible for the change in the landmasses. Since the image shows movement of continents to their current positions, their surfaces would have been sculpted by the agents of denudation through its 250mya history.
- Denudation is the gradual process of lowering and leveling of the earth surface by breaking and wearing away of such surfaces.
- The agents of denudation are wind, running water, ice and waves.
- Denudation is a constant process that the earth undergoes from time to time.

The total distance from jade's house to school is 5 times the distance from the coffee shop to her school = 7.5 miles
Distance is the overall movement of an object without any regard to path. we will outline distance as to how a lot ground an object has protected regardless of its starting or finishing point.
Equation;
Let the distance between coffee shop and school = X
Distance from Jade's house to coffee shop = 3 miles +2x
Total distance from Jade's house to school = 5*X
∴ the total distance = house to coffee shop + coffee shop to school
⇒ 5X = (3 + 2X + X)
⇒ 5X = ( 3 +3X)
⇒ 2X = 3
⇒ X = 1.5 miles
Therefore,
Distance = house to school = 5 * 1.5 = 7.5 miles
coffee shop to school = 1.5 miles
house to coffee shop = 3 + 2*1.5 = 6 miles
Hence, The total distance from jade's house to school is 5 times the distance from the coffee shop to her school = 7.5 miles
