When it's beneath the surface, the molten rock is called magma. When it reaches the surface, it erupts as lava, ash and volcanic rocks. With each eruption, rocks, lava and ash build up around the volcanic vent. The nature of the eruption depends on the viscosity of the magma.
Answer:
The answer is Option B: plate tectonics.
Explanation:
Plate tectonics is a theory about the structure of the earth's crust. In plate tectonics, the continents are viewed as a part of a system of rigid lithospheric plates which move slowly over the underlying mantle of the Earth. The model for plate tectonics builds on the concept of continental drift, which is an idea developed during the first decades of the 20th century. In continental drift theory, all the world's continents were once joined into a land mass that geologists have called Pangea during the late Paleozoic and early Mesozoic eras. It began to break up about 175 million years ago. In the beginning in the late Triassic, the continents began to break up with Laurasia comprising with what is North America and Eurasia and Gondwanaland which was South America and Africa, India, Arabia, Antarctica, and Australia. The shift in plates and their movement create mountain ranges and continents form and move to different latitudes that change the climate as these land masses moved.
True - for there are some insects that are resistant for example there are few types of beetles.
Hope this helps
Answer:
This statement is true since the formation of this ocean arose 200 million years ago, making it the last in shape during the division of the Pangea supercontinent.
Pangea began to fragment due to the force of Earth's tectonic plates, separating the ancient continent of America and leaving a large body of water in between.
Explanation:
The second major phase of Pangea's disintegration began at the beginning of the Cretaceous (150-140 million years ago), when the supercontinent Gondwana divided into four smaller continents (Africa, South America, India, and Antarctica / Australia).
Answer:
thermohaline circulation
Explanation:
Thermohaline circulation occurs through the difference in density between the waters of the sea current in relation to the temperature and the amount of salt that they present. Thus, this oceanographic phenomenon makes the waters with the highest concentrations of salt, the surface waters in the North Atlantic, near Greenland, are swallowed by the part with the lowest concentration, sinking completely and causing a turnaround in the maritime space. This throws the waters with the lowest salt concentration upwards, displacing the deeper waters and attracting the warm tropical surface waters
