What type of boundary is created by seafloor spreading?

• divergent

• convergent

• transform

Answer explanation

Seafloor spreading occurs at divergent boundaries where tectonic plates move apart, allowing magma to rise and create new oceanic crust. This process is fundamental to the formation of mid-ocean ridges.

What type of boundary is this?

• convergent

• divergent

• transform

Answer explanation

A transform boundary occurs where two tectonic plates slide past each other horizontally. This movement can cause earthquakes, making 'transform' the correct choice among the options provided.

What type of boundary is this?

• convergent

• transform

• divergent

Answer explanation

A convergent boundary occurs where two tectonic plates move towards each other, often causing one plate to be forced beneath the other. This is why the correct answer is 'convergent'.

What type of boundary is this?

• convergent

• divergent

• transform

Answer explanation

A divergent boundary occurs where tectonic plates move apart, allowing magma to rise and create new crust. This process is characteristic of mid-ocean ridges, making 'divergent' the correct choice.

Which is a plate boundary where both plates move away from each other?

• divergent

• plate

• convergent

• transform

Answer explanation

A divergent plate boundary occurs when two tectonic plates move away from each other, allowing magma to rise and create new crust. This is in contrast to convergent boundaries where plates move towards each other.

What type of boundary does a fault create?

• divergent

• convergent

• transform

Answer explanation

A fault creates a transform boundary, where two tectonic plates slide past each other horizontally. This movement can cause earthquakes, distinguishing it from divergent and convergent boundaries.

• the mantle

• magma

• tectonic plates

Answer explanation

The surface of the Earth is divided into large slabs of rock known as tectonic plates. These plates float on the semi-fluid mantle beneath them, and their movement is responsible for many geological phenomena.
