Could global warming heat the crust....?

Question

....and cause earthquakes.

Answer 1

In a word - no.

Heat transfer takes place from a warm medium to a cold medium. The Earth's crust is hot (apart from the surface of it), heat is radiated upwards and outwards from the Earth's crust.

The Earths's crust is somewhat like a cracked eggshell, made up of many sections floating on the liquid mantle beneath the crust. These sections are called tectonic plates and they move very slowly (between 1 and 16cm a year). Sometimes they move apart from each other and effectively cause a giant tear in the Earth's surface - the Rift Valley in Africa is a good example of this, other plates collide and are pushed upwards at the point of impact, this creates mountain ranges and the Himalayas are a good example of this type of mountain building.

Sometimes when two plates push against each other they become jammed, the pressure increases until one plate suddenly yields and is forced upward of downward. It's this violent movement and immense release of energy that results in Earthquakes.

Global warming could affect earthquake activity if it were to melt vast amounts of the ice at the ice caps, this would alter the balance of the planet slightly and result in greater or lesser forces pushing downward on the tectonic plates. However, for all intents and purposes you can discount the role of global warming in respect of earthquakes (for well into the future at least).

Answer 2

The Earth's crust is composed of a sequence of super plates - tectonic plates. each and every so often those collide with one yet another and reason an upthrust premier to mountain chains such through fact the Himalayas, different plates are moving faraway from one yet another and actually tearing the Earth open, the super Rift Valley in Africa is a sturdy occasion of this. the cost at which the worldwide ameliorations geologoically is minute, plate strikes of something fairly a quantity mm a 300 and sixty 5 days would be seen intense. those strikes can crack open fissures and bring about different geological activities at the same time with earthquakes however the're no longer in charge for worldwide warming. surely, geological activities which result interior the launch of fabric from below the Earth's floor make a contribution to worldwide cooling. the clarification being that the fabric released, fairly sulphur dioxide, blocks out photograph voltaic. worldwide warming is happening regardless of the undeniable fact that this is for terribly distinctive motives.

Answer 3

It could heat the crust very slightly.. but it's effects on the crust will be nominal. A few degrees (which is what we are talking about with global warming) is enough to effect climate and weather patterns... it's not really anywhere near enough to effect rock and dirt (other than the effects from altered weather obviously)

Answer 4

Global warming could affect earthquake activity if it were to melt vast amounts of the ice at the ice caps, this would alter the balance of the planet slightly and result in greater or lesser forces pushing downward on the tectonic plates. However, for all intents and purposes you can discount the role of global warming in respect of earthquakes (for well into the future at least).

Answer 5

I was wondering when someone was going to blame earthquakes on global warming. It seems unlikely to me that could happen, but I have no evidence one way or the other.

Answer 6

NO !!!

After just some kilometers, the natural nuclear decay in the earth crust is the main source of heat, by far exceeding the amount of energy brought by the sun !

Answer 7

Not likely. Earthquakes are primarily caused by plate movements driven by forces deep within the earth, and not likely to be affected by surface temp changes

Answer 8

NO it is caused buy the molten liquid under the crust moving about

Answer 9

Nope, Those two are completely different and are not related.

Answer 10

yes & much much worse.
