a. It has a liquid water; almost 70%
b. Plate tectonics
c. has a atmosphere
how many amount of water had of earth?
70%
4 factors that make Earth habitable
- Temperature
- Atmosphere
- Energy
- Nutrients
why Earth is considered as habitable?
a. has a right distance from the sun
b. protected from harmful solar radiation by its magnetic field
c. has the right amount of ingredients for life, including watrr and carbon
earth is different from other planet because?
Earth is the only planet that have a liquid water on the surface
similarities of earth, venus, and mars
a. They all have a terrestrial planets
b. They all have atmosphere
c. They all almost have the same time to rotate in their axes
d. Earth and Mars both have a water
e. All have a carbon dioxide
f. All have a landforms
earth, venus, and mars differences
a. Venus has no water
b. Venus and Mars don’t have a oxygen
c. Earth has life forms
known as harbour life
Earth
What is the Earth’s Subsystem
Atmosphere ( air )
Hydrosphere ( water )
Lithosphere ( land )
Biosphere ( living things )
The blanket of gas that surrounds Earth to help keep us warm, it also protect js from harmful solar radiation
Atmosphere
Came from the word “hydro” which means water
Hydrosphere
Came from the word “litho” which means stone or rocks
Lithosphere
Came from the word “bio” means life, and it consists kf of all living things
Biosphere
What is building blocks of Rocks
Minerals
2 properties of minerals
Chemical Composition and Crystalline Composition
Components of matter that cannot broken into simpler particles
Elements
Characteristics of shape of an individual _______,
Help convey the shape of a crystal. Bladed, cubic, granular, prismatic
Crystal Habit
Tendency of some minerals to break along flat surfaces
cleavage
The Manner in which Mineral breaks other than along planes of cleavage
Fracture
The resistance of a mineral to SCRATCHING, controlled by the bond strength between its atoms
Hardness
Formula for calculating the specific gravity
specific gravity= density of the o object / density of water
Most obvious property of a Mineral, oftrn used in indentification
Color
Color of the fine POWDER of a mineral, usually obtained by rubbing the mineral
Streak
The quality and intensity of light reflected from the surface of a mineral
Luster
Minerals reaction to stress or minerals toughness and resistance to breaking deformation
Tenacity
What is types of tenacity
Brittleness
Malleability
Ductility
Flexible but inelastic
Flexible but elastic
Sectility
Its Study the Minerals
Geologists
Chemical elements include silicon and oxygen…
Silicates
Chemical elements include carbon and oxygen as major part of their chemical composition
Carbonates
Chemical elements include sulfur bonded to a metal ion
Sulfide
Consist kf only one element and thus the element occurs in native state
Native Element
