Answer:
Seafloor spreading occurs at Feature A and subduction occurs at Feature B
Explanation:
The mid-ocean ridge is the place where the ocean floor spreads. This feature can be found where two plates are moving away from one another. The gap that they live between them enables the magma from the mantle to easily rise up. As the magma comes to the ocean floor, it cools off and creates new crust. As the magma continues to come out, it builds up, creating an underwater mountain chain, known as a mid-ocean ridge.
The ocean trench on the other side, is the place where one plate moves below another plate, thus subducting. As the plate is subducting, it reaches the mantle layer, so its crust is melted by the high temperatures, resulting in the destruction of that crust.
Answer:
Negative punishment.
Explanation:
As the exercise briefly describes, when a stimulus is removed from a person or animal, resulting in a decrease in the probability of response, it is known as negative punishment. In behavioral terms, positive means adding whereas negative means taking. The goal of punishment is to decrease a determined behavior. Therefore, if a person takes something good for example a dog's bone, when the dog behaves poorly, it will likely decrease this response. And, if the dog behaves well, and you give him the bone, this will make him tend to act like that.
The first person to sail around Africa and to reach India ( and to get some precious spices from there!) was Portuguese Vasco da Gama, who did this in his journey that started in 1497 and reached India in 1498 ( and returned in 1499)
