Tectonic Theory
What are tectonic plates?
A tectonic plate is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere (crust and upper mantle).
We did an experiment that has showcased the movement of convection currents in the mantle in a simple way. So give the name of this small experiment.
Movement of biscuit (tectonic plates) in a viscous liquid, the rising syrup (mantle).
Give a term for stellar nursery
A stellar nursery is a place for stars to be born. Word stellar relates to stars, and nursery is a place to care for young people, animals or plants
Give the names of three hypothesises that is about formation of them moon
Capture Hypothesis
Accretion Hypothesis
Collision Theory
What's the name of the protoplanet that hit the earth?
Theia is the protoplanet which has hit the earth
Give 4 evidences for tectonic plates
The Jigsaw appearance of continental coast
Location of volcanoes and earthquakes
Fossil records
Alignment of magnetic materials in the Earth's crust
Define Convection Currents
Convection currents transfer heat from one place to another by mass of a fluid. Air warms and rises; air cools and sinks.
If you live in the ______ hemisphere, the Tarantula Nebula is the easiest one to see. It can be seen by human _____ eyes, but it wouldn't seem as colourful as the picture that is taken by a powerful telescope
If you live in the southern hemisphere, the Tarantula Nebula is the easiest one to see. It can be seen by human naked eyes, but it wouldn't seem as colourful as the picture that is taken by a powerful telescope
Explain the giant impact theory which has occured with protoplanet
Theia the protoplanet collided with the earth and caused ring of rocks and dust. They moved around the earth and created the moon.
What is accretion? (define it)
The process of growth or increase
Why can volcanoes occur away from the plate boundaries? Give the reason, name, and creator of the theory.
Yo, want some superpowers? Get the question right; otherwise: [...]
There are some places that contain exceptionally fixed areas in the mantle that melt the tectonic plates that move above them.
This theory was created by John Tuzo-Wilson and the name of the theory is "Hotspot theory."
CORRECT - Take 10 % of the points from whoever you want or +200 points🤩
INCORRECT - Lose 20 % of your score. 😶
Give me the name of a person and the decade in which he has proposed that "Even tectonic plates are moving apart and making new crust, they can't make Earth grow in size."
In the 1960s, a scientist called Harry Hammond Hess proposed that the ocean floor spreads on either side from a mid-ocean ridge like a conveyor belt.
Give 2 names of gases that nebulae are made up
What's the size of the most nebulae compared to our solar system
Hydrogen and Helium
10,000 bigger than our solar system
Give three evidences that support Collision Theory
The Earth's spin and the Moon's orbit have similar orientations – this supports an impact by a large object
There is evidence in other star systems of similar collisions
The Moon has a relatively small iron core – the Moon formed mainly from debris from the outer layers of the Earth which have less iron than the core.
When the Indian plate and Eurasian Plate collided and still forming?
They began to form about 50 million years ago, when the Indian Plate collided with the Eurasian Plate, and they are still forming.
What is a "Hypothesis", "Theory" and a "Law"?
(Find at least 2 of them to be accepted as correct)
Hypothesis is a testable explanation to a question
Theory is supported by large body of scientific evidence
Law describes what nature does under certain condition (can be reduced to mathematical equation)
When was the Mid-Atlantic Ridge was discovered?
The Mid-Atlantic Ridge was discovered in 1872
How stars are formed (give at least 3 steps)
1) In a stellar nursery, the dust and gas collapse together under the force of gravity.
2) When the mass of dust and gas collects together and becomes larger, the gravitational forces pulling inwards increase.
3) When the force gets very large, the pressure gets increased. If the pressure is high enough to cause loads of heat, it'll become a star. Otherwise it'll become a planet
Someone has proposed a new hypothesis. She/He suggests the Earth and Moon formed together from the impact of two protoplanets. Give me the name of the scientist and the year she proposed this hypothesis
In 2012, Robin M. Canup has suggested this hypothesis
What is the size of our moon? For you, you can only say the number till hundreds (Examle: if the number is 3735, you can say 3700. But it is not the correct answer)
1737 km or 1079 miles
Where the magnetic crystals in rocks have been found? What are these locations are called?
The magnetic crystals in rocks found in the middle of the Earth's oceans. These locations called mid-oceanic ridges
How Red Sea is formed (say the tectonic plate names)? What convection currents caused?
In African and Arabian plate, convection currents cause seafloor spreading. That's how red sea is formed
Once, NASA launched a large telescope that orbits the Earth. Give me the name of it and the year it was sent to space. (If you find the answer you'd have a powerful ability or if you can't, something bad is waiting for you...)
The Hubble Space Telescope is a large telescope that orbits the Earth. It was launched by NASA in 1990 and has been used to take very clear pictures of space because it is above Earth's atmosphere.
TRUE - SWAP or Deduct 50 points from everyone. 😆
INCORRECT - Add all digits of the time right now (minutes and hours only) and put a zero at the back. Subtract this number from yourself. 🤐
How many samples of rocks did the Apollo mission bring back?
If you find the correct answer something amazing iz waitin for you...
If you can't, [...]
The Apollo missions brought back 2200 samples of Moon rock
What is the Peru-Chile Trench known as? Which 2 tectonic plates are participated in this formation of the trench?
If you find the answer, you'll have an ability to [...]😎
If you can't, you'll pay with some of you points 😏
The Peru-Chile Trench, also known as the Atacama Trench. It delineates the boundary between the subducting Nazca Plate and the overriding South American Plate.
CORRECT - add points as the number of the highest team has got 🤑
INCORRECT - minus the quarter points of the highest team ☠
