問題一覧

are ideas or explanations that do not adhere to the scientific method and lack empirical support. Includes philosophical concepts, religious beliefs, etc

Non- Scientific Theories

based on observation, experimentation, and evidence.

Scientific theories

These theories propose that a divine being or force created the universe

Creationist Theories

How old are young earth creationism?

6,000 years ago

how old are old earth creationism?

13.6 billion years ago

The emergence of the universe began as incredibly hot dense point, smaller than subatomic particles. It comes from a big explosion

BigBang Theory

how old is the Methuselah star?

14.46 billion years old

Who proposed the bigbang theory?

Georges Lemaitre

An alternative cosmological theory suggest that the redshift or light from distant galaxies is due to light losing energy as it travel through space as opposed to the expansion of universe

Tired Light Hypothesis

The universe has no beginning or end and remains or unchangeable in a constant state

Steady State Theory

Who proposed the steady state theory?

Fred hoyle, Thomas Gold, Hermann Bondi

Theory about the formation of solar system

Nebular hypothesis

rotating disk of gas and dust surrounding a newformed star

Protoplanetary disk

Solid particles began to stick together and collide, forming planetesimals

Planetesimal Formation

Rocky planets mostly composed of iron and nickel

Terrestrial planets

Gas planets or gas Giants mostly consist of helium and gas

Jovian planets

The smallest and close to the sun

Mercury

Hottest planet

Venus

only planet that can support life and habitable

Earth

Red planet

Mars

Largest planet

Jupiter

Known for its beautiful rings

Saturn

Icy planet

Uranus

Blue planet with great dark spots

Neptune

What layer of the earth does most earthquakes occur?

Crust

Layer of the earth that generates magnetic field

Outer core

How many percent does crust makes up of the earth?

Two types of crust

Oceanic, Continental

Largest layer of the earth

Mantle

Two regions of mantle

Upper mantle, Lower mantle

This is where magma is stored

Upper mantle

is the outer layer of the mantle

Asthenosphere

- Middle layer - Very thick layer - This where convection current occurs

Lower mantle

It is the liquid layer

Outer core

It is the solid layer

Inner core

Who discovered the discontinuity between crust and mantle?

Andreja Mohorovicic

Who discovered the discontinuity between mantle and outer core?

Beno Gutenburg

Who discovered the discontinuity between outer core and inner core?

Inge Lehmann

The movement of tectonic plates leads to the formation of folds primarily at convergent boundaries where plates collide.

Plate movement

Upward arching folds where the oldest rocks are found at the center

Anticlines

Downward arching folds where the youngest rocks are found at the center

Synclines

Folds where one limb is tilted beyond vertical

Overturned folds

At convergent boundaries, where plates collide, the crust is compressed causing it to fold and fracture. This compression can create a reverse or thrust faults.

Compression

At divergent boundaries, where plates pull apart, the crust is stretched and thinned, leading to normal faults.

Tension

At transform boundaries, where plates slides past each other horizontally, shear stress cause horizontal displacement along strike slip faults.

Shear stress

Is a geologic process in which tectonic plates split apart from each other

Seafloor spreading

is the process where new oceanic crust is formed at the mid ocean ridges and slowly moves away from the ridge, expanding the ocean floor.

Seafloor spreading
