A volcanic eruption releasing rock, ash, and dust particles into the air is an example of which interaction?
the biosphere interacting with the geosphere
the geosphere interacting with the atmosphere
the geosphere interacting with the hydrosphere
the hydrosphere interacting with the atmosphere
The interaction described is that of the geosphere interacting with the atmosphere.
The geosphere refers to all the rock and mineral materials that we have on our planet including:
Lava in the mantle Soil Mountains and everything made of rockThe atmosphere is the air that surrounds the Earth including gases like Nitrogen and Oxygen.
When a volcano erupts therefore, it is releasing rock (geosphere) into the air (atmosphere).
As a result, we can conclude that a volcano erupting is an interaction between the geosphere and the atmosphere.

Which part of the angle is the vertex?
A. AB
B. Point A
C. AC
D. Point C
Answer:
Point A
Step-by-step explanation:
The vertex is where the two rays meet together
A is the vertex
The vertex of the angle is the shared endpoint of the two rays [tex]\underset{AB}{\rightarrow}[/tex] and [tex]\underset{AC}{\rightarrow}[/tex], that is, the vertex is at Point A. Hence, option B is the right choice.
What is a ray?A ray is made up of a half-line and its endpoint.
If a ray has an endpoint A and a B that is any other half-line point, then the ray is represented by [tex]\underset{AB}{\rightarrow}[/tex].
What is an angle?A pair of rays with a shared endpoint form an angle.
The rays are referred to as the angle's sides.
The shared endpoint is referred to as the angle's vertex.
How do we solve the given question?We are asked to identify the vertex of the given anis
The given angle is made of the rays [tex]\underset{AB}{\rightarrow}[/tex] and [tex]\underset{AC}{\rightarrow}[/tex], the shared endpoint is at Point A.
As we know, the shared endpoint is the vertex of the angle, so Point A is the vertex of the given angle. Hence, Option B is the right choice.

The degree of rotation will be equal to 24°.
It is given that we have a regular 15 sided polygon.
We need to find out the degree of rotation for it.
What is the formula to determine degree of rotation ?
The formula of degree of rotation is given by Degree of rotation = 360° / Number of sides.
As per the question ;
We have a regular 15 sided polygon.
or
No. of sides of regular polygon = 15
We know that ;
Degree of rotation = 360° / Number of sides
⇒ Degree of rotation will be equal to ;
= 360° / 15
= 24°
Thus , the degree of rotation will be equal to 24°.
