how long ago the big bang happened
A. 10.9 billion years ago
B. 26.6 billion years ago
C. 11.7 billion years ago
D. 13.7 billion years ago
What is D. 13.7 billion years ago
100
when a high mass star explodes
What is supernova
100
the last element made by stars witch also kills them
What is iron
100
define core
What is The dense center of the Earth, made mostly of iron, and some nickel. The movement of molten iron and nickel in the outer core generates the Earth's magnetic field.
100
one way people misused Darwins ideas
What is sterilization, survival of the fittest, eugenics, immigration
200
The process by which planets form as material orbiting some stars gathers together through collisions and gravitational or electrostatic attraction, eventually forming larger and larger bodies.
What is accreation
200
what is the last cycle of a low mass star
What is black dwarf
200
The most common chemical element in the planet Earth, iron forms the majority of its inner and outer core. The process of creating new elements through nuclear fusion in stars ends with iron as there is not enough energy in a star’s core to fuse two iron atoms together and form any heavier elements.
What is iron
200
The solid outer layer of the Earth, consisting of moving plates both of the continental (lighter, made of granite) and oceanic (heavier, made of basalts) varieties.
What is crust
200
Four commonly accepted attributes of life are that it uses energy from the environment by eating or breathing or photosynthesizing (metabolism); it makes copies of itself (reproduction); over many generations it can change characteristics to adapt to its changing environment (adaptation); and it can regulate internal conditions in order to maintain a stable state (homeostasis).

What is gravity, time, space, quarks, electrons, electromagnetism,
300
define cluster
What is A group of galaxies held together by their mutual gravitational pulls.
300
3 of the 7 elements during a stars death cycle
What is carbon, iron, oxygen, neon, silicon, helium, hydrogen
300
happened to the solar system about 4.5 billion years ago
when did the sun formed
300
one of the Goldilocks conditions for life on earth
What is liquid water, the right amount of energy
400
Nicolas Copernicus was the first to say this
What is the sun is the center of the universe
400
the type of star our star is our sun
What is main sequence low mass
400
The combining of lighter atomic nuclei into heavier atomic nuclei. This process can release a great deal of energy, and is what powers most stars.
What is fusion
400

What is hadeon, accretion, protozoic, Phanerozoic
400
how long ago life first appeared
What is 4 billion years ago
500
the Goldilocks conditions of the big bang
What is we can only speculate
500
the time a supernova last
What is seconds
500
define carbon or how it is formed to stars
What is A chemical element with six protons that is formed in the death cycle of medium and large stars. Carbon is the basis for all known life on Earth.
500
name the eons in order of time
What is Hadean, Archean, Proterozoic, Phanerozoic
500
The capacity of living organisms or cells to regulate internal conditions (for example, temperature) in order to maintain a stable state.
