What causes the tectonic plates to move according to the most widely accepted theory? A. External impacts from asteroids B. Convection in the asthenosphere (a part of the mantle) C. Chemical reactions in the core D. Changes in sea - level 相关知识点: ...
They will move towards the equator over time C. Their body size will become much smaller D. They will start to hibernate all year round 相关知识点: 试题来源: 解析 B。解析:当板块运动使一些大陆向极点移动时,环境会变得寒冷。原本生活在这些大陆的温血动物为了寻找更适宜的温暖环境,会随着时间向...
Tectonic plates move because the Earth is constantly trying to dissipate itsinternal heat. The heat from the planet’s core drivesconvection currentsin the mantle, which creates a dynamic system where tectonic plates are carried along the surface. Additionally,gravityassists in pulling the plates at...
They move side to side, back and forward, all various ways. Slightly. This is called tectonic flow or something like that (forgotten). Each tectonic plate moves in their own direction. Which part are the tectonic plates in? It isn't in anything, it is on top of the earth crust. ...
between the plates generates friction. A lot of the boundary areas are near the shoreline of the ocean, which is one reason why those areas are often more prone to geological activity. Studies have shown that the continents move at a speed roughly equivalent to 4 inches (about 10 cm) per...
What Happens to Google Maps When Tectonic Plates Move?George Musser
. Hot magma flows up through spaces created between tectonic plates as they move. . Hot magma flows up at a point where a tectonic plate has been stretched thin.5、What is the professor’s opinion of the two main hypotheses he presents? . Neither hypothesis can explain the formation of ...
Earthquakes happen all the time, on land and in the ocean – but the majority are so small that people do not even feel them. "The surface of the earth is made of tectonic plates, which are about 100 kilometers thick, they move around together. So when they collide or ...
Tectonic plates move at a rate of 1 to 2 inches (3 to 5 centimeters) per year,according to National Geographic. That's about as fast as your fingernails grow! How many plates are there? Because Earth is spherical, its tectonic or lithospheric plates are fractured into dozens of curved sec...
The instrument that measures seismic waves is called a seismometer, or seismograph. Seismic waves are energy waves that move in different layers under... Learn more about this topic: Seismograph | Definition & Measurement from Chapter 21/ Lesson 13 ...
