Minerals

Question 1

What’s crystallization?

Answer 1

Magma, that’s molten rock cools over time and solidifies. It can occur beneath or above the surface.

Question 2

What’s igneous rock?

Answer 2

Rocks formed from the crystallization of magma.

Question 3

What’s weathering?

Answer 3

Influences of the atmosphere slowly disintegrate and decompose rocks.

Question 4

What’s sediment?

Answer 4

Particles or results of weathering and erosion which is carried

Question 5

What’s lithification

Answer 5

Sediments converge into sedimentary rocks.

Question 6

What’s sediment rock?

Answer 6

Rock is formed by the weathered products of a preexisting rock (ex: igneous undergoing weathering, sediment, and lithification) and has been transported and lithified.

Question 7

What’s a metamorphic rock?

Answer 7

Preexisting rock deep within the Earth that’s already a solid state but is altered by heat/pressure, or chemically active fluids.

Question 8

Alternative path for igneous rock?

Answer 8

Instead of weathering, igneous rocks can be buried deep subjected to intense heat and pressure becoming metamorphic.

Question 9

An alternative path for metamorphic rock?

Answer 9

Can be transported by weathering undergoing sediment and lithification to sediment rock.

Question 10

Hydrologic cycle

Answer 10

Enough time, water can be everywhere

Question 11

Geologic time

Answer 11

Different eons, eras, periods, epics

Question 12

Atom

Answer 12

Smallest fraction of an element

Question 13

What are the main part of an atom?

Answer 13

Protons, neutrons, neutrons

Question 14

Electron cloud

Answer 14

Where the electrons are

Question 15

What’s atomic number?

Answer 15

The protons in a nucleus. Uncharged atom, this is the same as electrons

Question 16

What’s an Ion?

Answer 16

A charged atom has differences in protons and electrons. Uncharged has the same amount of pro and elc

Question 17

What’s an mass number?

Answer 17

Protons and neutrons in the nucleus

Question 18

What’s an isotope?

Answer 18

same amount of protons + electrons but different amount of neutrons

Question 19

What would evaporate first O16 or O18?

Answer 19

O16 is lighter because it has 8 neutrons instead of 10.

Question 20

Octet rule

Answer 20

The tendency to have 8 electrons.

1-3 electrons will go away
5-7 electrons will collect to make 8
4 can either gain or lose electron
8 electrons are noble gasses

Question 21

What’s the story of minerals?

Answer 21

In the past there were only 12 minerals and in the present now there’s 4300 mineral groups.

Question 22

How did minerals evolve when the Sun became luminous 4.56 Ga (giga anum= 1 billion years ago)?

Answer 22

Went from 12 to 60 minerals just by adding heat

Question 23

How did h2o contribute to mineral groups increase 4.55 Ga?

Answer 23

Aqueous and Thermal heat alteration and now increased to 250 minerals.

Question 24

What else formed 4.55-3.5 Ga?

Answer 24

Clay, evaporates, Chemical interactions and 350-500 new minerals.

Question 25

What else formed 4.0-3.5 Ga?

Answer 25

Granite/contential rocks
