GEOLOGY

Detailed explanation-1: -At conservative plate margins, tectonic plates slide past each other. There is no volcanic activity associated with conservative plates, though earthquakes can often occur. This is because plates do not pass each other smoothly; friction causes resistance.

Detailed explanation-2: -This type of transform boundary produces shallow earthquakes and accompanying ground faulting. The friction between the two plates is often so great that the two sliding margins become ‘stuck’ together, allowing stresses to build up, which are then relieved by large earthquakes.

Detailed explanation-3: -About 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on.

Detailed explanation-4: -Lithosphere is neither created nor subducted, and whilst conservative plate margins do not result in volcanic activity, they are the sites of extensive shallow focus earthquakes, occasionally of considerable magnitude.
