Answer:
Options (A), (B), (C), and (D)
Explanation:
The volcanic activity refers to the eruption of magma at the surface of the ocean floor and continental land areas, forming volcanoes.
Some of the tectonic settings that are associated with volcanic activity are as follows-
- Mantle plumes- These are the large uprising bodies of magma that are generated due to the formation of convection current in the mantle. These are localized body and are located away from the tectonic boundaries. For example, Hawaii is formed as the plates moved over the mantle plumes.
- Continental rifts- This refers to the eruption of magma at the surface of the continents, due to the divergent motion of two continental plates. It results in the formation of a rift, rift valley and then later forms an ocean.
- Island arcs- These are formed due to the collision of two oceanic plates, where the volcanoes are formed on the lighter oceanic plate due to the rising up of magma.
- Continental arcs- These are formed due to the collision between an oceanic and a continental plate, where the volcanoes are formed due to the uprising of magma in the lighter continental plates.
Answer:
Well, I'm not sure because degrees Fahrenheit doesn't show. The degrees Celcius depends on Fahrenheit.
Explanation:
Answer:
there's a few processes I've learned of that creates landforms.
Events such as landslides, floods, and other natural changes in nature can cause land to change shape.
Physical weathering and erosion also can cause land formation. The rocks that break down changes the shape of land.

Answer:
The perimeter of the triangle is 2+√2
Explanation:
Since one of the angles of the triangle is 90°, the triangle in question is a right angled triangle.
Since two angles of the triangle are also equal, then two of the its sides will be equal.
Let the opposite and the adjacent sides of the triangle be 1. To get the hypotenuse side, we will apply the Pythagoras theorem which States;
Hypotenuse² = Adjacent²+opposite²
Hyp² = 1²+1²
Hyp = √1²+1²
Hyp = √2
The third side of the triangle is √2.
The perimeter of the triangle will be the sum of all its sides i.e 1+1+√2
= 2+√2
The perimeter of the triangle will be 2+√2
