Answer:
it is under secondary industry
Answer:
The crust size remains constant because the older crust is melted at subduction zones.
Explanation:
The crust is constnatly created on Earth, but the crust is constantly getting destroyed as well. This situation leads to the total size of the crust being roughly at the same level, or rather constant, as one side a new one emerges, while at the same time, on the other side it gets destroyed.
The vast majority of the new crust is formed where there are divergent plate boundaries. Here, a gap opens up between the plates that move away and magma is constantly rising to the surface and creates new crust. When it comes to the destruction of crust, it occurs at subduction zones. Here, one plate moves below another plate, and as it does it reaches the upper mantle where it gets melted and recycled because of the high temperatures and pressure.
Answer:
On the oceans of the Earth, gravity and inertia work in opposition, causing tidal bulges on opposite sides of the planet. The moon's gravitational force pulls the ocean's waters toward it on the "near" side of the Earth (the side facing the moon), resulting in a bulge.
Explanation:
Answer:
a) w = 98°
b) x = 137°
Explanation:
The reason is that they are angles at a point
Which means they are equal to 360°.
Example;
a) 165° + 97° + w = 360°
262° + w = 360°
You then group like terms
w = 360° - 262°
w = 98°
Note: The reason is the same for b)
The word minerals mean A formal definition of a mineral, as used by geologists would be: A naturally occurring inorganic solid that has a definite chemical composition, and an ordered internal structure. Geologists are able to identify minerals because they have characteristic physical properties.
