What's true about the continental drift theory?
All scientists believed it since its development by Alfred Wegner.
One evidence that proves it is that the earth was always separated in different continents.
One evidence that proves it is that fossils of some animals and plants of the same species were found in separated parts of the Earth.
The continents broke apart in a couple of years to form what we see now.
Which alternative complements the following idea: "Continental drift was a theory that explained how continents shifted position on Earth's surface. "
"For example, fossils of the ancient reptile mesosaurus are only found in southern Africa and South America."
"It explains that Earth's crust is fractured into rigid, moving plates."
"Millions of years ago, it broke up and drifted to their current positions."
"But geologists didn’t believe it, because Wegner didn't have a good model to explain how the continents moved apart."
ABOUT MOUNTAINS’ FORMATION IT’S CORRECT TO SAY.
Old mountains tend to be steep and pointy due to the process of erosion.
Mountains only form when tectonic plates diverge.
All mountains are formed over millions of years.
Volcanic mountains can be formed in only a few days.
Dome mountains are created when _______ rock called _____ pushes up below the surface of the Earth, forming a bump.
(a)
Which of the following measures the size of an earthquake?
Seismograph
Tachometer
Thermometer
Monograph
Which of the following statements is not true?
An underwater earthquake can cause a tsunami.
The hot molten rock deep below Earth's surface is called lava.
A volcano is a rupture on the crust of the Earth.
The Earth's crust is constantly moving throughout the world.
Which of the following can cause a tsunami? Mark the possible options.
earthquakes
landslides
a mountain forming
a ship accident
WHY IS THE LOCATION OF THE INDONESIAN ISLANDS CALLED THE “RING OF FIRE”?
It refers to the area where wildfires are more common.
Because it’s where tectonic plates drift apart causing the separation of continents.
It’s where seismic activities are rare.
It refers to the area when the activities of tectonic plates cause more natural disasters.
WHAT’S TRUE ABOUT THE STAGES OF VOLCANOES?
A dormant volcano is the one which has erupted some years ago, and there is a possibility that it will erupt again in the future.
Volcanoes that erupted thousands of years ago and there isn’t a possibility to erupt again are considered dormant.
An active volcano is the one that has erupted recently, but won’t erupt again anytime soon.
An extinct volcano will erupt in the near future.
WHAT’S INCORRECT ABOUT THE FORMATION OF VOLCANOES?
They can be formed on both land and in the ocean around the boundaries of tectonic plates.
They are formed when a continental plate moves under the oceanic plate, in the subduction zone.
They are formed when tectonic plates diverge and magma from the earth's upper mantle rises up to fill the spaces.
When volcanoes form in the ocean, they form new crust on the surface because the magma cools down.
