What are the things common to two pictures but not on the other?
Therefore, the things that are common to two pictures but are not found on the other is that the first picture only has one person, while the other two pictures have two people in them. Also, the person in the first picture is projecting directly at the camera, while the other two pictures are not.
What negative lifestyles are depicted in the picture?
Answer: The negative lifestyles that are depicted in the pictures are cigarette smoking, eating unhealthy foods, drinking alcohol, sleep deprivation, polluting the environment etc.
What can you say about the relative motion of blocks 1 and 2 How about 3 and 4?
Answer Expert Verified It shows relative motions between block 1 and 2 and between blocks 3 and 4. It was observed that the block 2 is moving or separating away from block 1, while block 4 is moving or separating away from block 3.
What do you think is happening to the Earth’s crust in those pictures?
What do you think is happening to the earth’s crust in those pictures? Answer: The land masses are moving away from each other creating fissures and cracks on the surface and eventually the two land masses will divided by ocean water.
What are the common four pictures?
What are common in the four pictures?
- Waterfalls.
- Valleys.
- Ridges.
How thick is the crust of the earth?
about 30 km
How far can a human go underground?
12 kilometers
Is the crust the thinnest of the major subdivisions?
The Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core and the inner core. Out of them, the crust is the thinnest layer of the Earth, amounting for less than 1% of our planet’s volume.
Which crust is thicker?
Earth’s crust is generally divided into older, thicker continental crust and younger, denser oceanic crust. The dynamic geology of Earth’s crust is informed by plate tectonics.
Which type of crust is less dense?
continental crust
Why is oceanic crust so dense and heavy?
Oceanic crust is denser because it generally melts to a higher fraction than continental crust. Generally lighter minerals melt before denser ones. When rocks melt to 20–30% like they do at mid-ocean ridges, the result is more dense than when rocks melt to form continental plates, which is typically 1–5%.
Why is the crust thicker under mountains?
The crust is thickened by the compressive forces related to subduction or continental collision. The buoyancy of the crust forces it upwards, the forces of the collisional stress balanced by gravity and erosion. This forms a keel or mountain root beneath the mountain range, which is where the thickest crust is found.
What is the largest tectonic plate on Earth?
Pacific Plate
What causes the tectonic plates to continually move?
The main driving force of plate tectonics is gravity. If a plate with oceanic lithosphere meets another plate, the dense oceanic lithosphere dives beneath the other plate and sinks into the mantle. The sinking oceanic lithosphere drags the rest of the tectonic plate and this is the main cause of plate motion.
How fast do tectonic plates move?
They move at a rate of one to two inches (three to five centimeters) per year.
