plate tectonics

Question 1

lithosphere

Answer 1

the rigid outer part of the earth, consisting of the crust and upper mantle.

Question 2

anthroposphere

Answer 2

The anthroposphere encompasses the total human presence throughout the Earth system including our culture, technology, built environment, and associated activities.

Question 3

mesosphere

Answer 3

The mesosphere is a layer of Earth’s atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere.

Question 4

inner core

Answer 4

nner Core The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1,220 kilometers (758 miles)

Question 5

outer core

Answer 5

Earth’s outer core is a fluid layer about 2,260 km (1,400 mi) thick, composed of mostly iron and nickel that lies above Earth’s solid inner core

Question 6

seismic waves

Answer 6

an elastic wave in the earth produced by an earthquake or other means.

Question 7

oceanic crust

Answer 7

oceanic crust, the outermost layer of Earth’s lithosphere that is found under the oceans and formed at spreading centres on oceanic ridges, which occur at divergent plate boundaries.

Question 8

continental crust

Answer 8

continental crust, the outermost layer of Earth’s lithosphere that makes up the planet’s continents and continental shelves and is formed near subduction zones at plate boundaries between continental and oceanic tectonic plates. The continental crust forms nearly all of Earth’s land surface.Oct 26, 2022

Question 9

density

Answer 9

Density is the substance’s mass per unit of volume. The symbol most often used for density is ρ although the Latin letter D can also be used.

Question 10

alfred wegener

Answer 10

Alfred Lothar Wegener was a German climatologist, geologist, geophysicist, meteorologist, and polar researcher. Alfred Wegener. Alfred Wegener ca.1924-30.

Question 11

continental drift

Answer 11

Continental drift is the hypothesis that the Earth’s continents have moved over geologic time relative to each other, thus appearing to have “drifted” …

Question 12

convergent boundary

Answer 12

A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as …

Question 13

divergent boundary

Answer 13

In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from …

Question 14

transform boundary

Answer 14

Transform boundaries are places where plates slide sideways past each other. At transform boundaries lithosphere is neither created nor destroyed. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. California’s San Andreas fault is a transform boundary.

Question 15

sea floor spreading

Answer 15

Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth’s lithosphere—split apart from each other. Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is the slow, churning motion of Earth’s mantle.Sep 27, 2022

Question 16

pangea

Answer 16

Pangaea or Pangea (/pænˈdʒiː.ə/) was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from the earlier …

Question 17

luarasia

Answer 17

Laurasia. / (lɔːˈreɪʃə) / noun. one of the two ancient supercontinents produced by the first split of the even larger supercontinent Pangaea about 200 million years ago, comprising what are now North America, Greenland, Europe, and Asia (excluding India)See also Gondwanaland, Pangaea.

Question 18

gondwana

Answer 18

Gondwana was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to …

Question 19

mesosarurus

Answer 19

What Were the Mesosaurs? During early Permian times (280–290 million years ago), life on land included several amphibians and lizard-like animals that were the ancestors of all the dinosaurs, reptiles, and mammals. Mesosaurus was a lizard-like animal that lived in South America and Africa during the Permian Period.Mar 7, 2019

Question 20

Glossopteris

Answer 20

Species of Glossopteris were the dominant trees of the middle- to high-latitude lowland vegetation across the supercontinent Gondwana during the Permian Period.
