GEOLOGY

Detailed explanation-1: -If two tectonic plates collide, they form a convergent plate boundary . Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common at subduction zones as well.

Detailed explanation-2: -When two plates carrying continents collide, the continental crust buckles and rocks pile up, creating towering mountain ranges. The Himalayas were born when the Indian subcontinent smashed into Asia 45 million years ago.

Detailed explanation-3: -Convergent plate boundaries occur when two plates move towards each other and collide. They can create mountains, volcanoes, and earthquakes. Divergent plate boundaries occur when two plates move away from each other and form a space between them.

Detailed explanation-4: -The Appalachian Mountains, along with the Caledonide Mountains in Greenland, the British Isles and Scandinavia, as well as the Atlas Mountains in northeastern Africa, are parts of a continental collision zone that formed 500 to 300 million years ago.

Detailed explanation-5: -Magma rises from the hot spots and erupts as lava through cracks in the Earth’s surface forming volcanoes. As a plate moves slowly across a hot spot, a chain of volcanoes or volcanic islands can form. The islands of Hawaii and Samoa were formed in this way.
