How many non- living systems does the Earth have ? |
5 |
|
|
What system is denser near the surface and be come less dense further ? |
Atmosphere |
|
|
The atmosphere contains mostly oxygen . True or false |
False ( It contains 78% Nitrogen ) |
|
|
Troposphere |
Bottom layer of atmosphere , The gasses swirl around , causes weather , temp. decreases as you move upward , contains most of the mass but is a thin layer |
|
|
Stratosphere |
Located above the troposphere, gasses more stable than troposphere and from flat layers, Location of ozone , Temp. increases |
|
|
Ozone |
Located in the stratosphere , filters ultraviolet (UV) radiation from the sun |
|
|
Mesosphere |
Temperature decreases with height throughout the mesosphere. |
|
|
Thermosphere
|
between mesosphere and exosphere , Temp. Increases |
|
|
Exosphere |
Last layer, Lowest density |
|
|
How much water is in the hydrosphere? |
1.3 billion km^3 ( 1,000,000,000 000 liters ) |
|
|
3 compositions of geosphere |
Core, mantle , crust |
|
|
Biosphere |
Contains all of the living things( Only living system ) |
|
|
Cryosphere |
frozen water part of the Earth |
|
|
Most of our fresh water is frozen . true or false |
True |
|
|
90 % of freshwater is in the Cryosphere. true or false |
False ( 79% freshwater ) |
|
|
How can you classify minerals |
Physical characteristics : Streak , color, hardness, luster , fracture / cleavage , crystal shape |
|
|
How do you classify rocks ( into igneous , sedimentary, metamorphic ) |
By how they are formed |
|
|
What is the difference between moving water and the solid part |
The moving water moves freely and the solid part can not |
|
|
What is composed of the oceanic crust ( metamorphic , sedimentary, igneous ) |
Only igneous rock |
|
|
What is composed of the continental crust ? ( metamorphic , sedimentary, igneous ) |
metamorphic , sedimentary, and igneous rocks |
|
|
What types of rocks is the crust made of |
metamorphic , sedimentary, and igneous rocks |
|
|
What is the mantle made of |
rocks ( hotter and denser rocks compared to crust ) |
|
|
what is the inner core made of |
solid iron |
|
|
what is the outer core made of |
More liquid ( made of nickel ) |
|
|
What is the order of the atmosphere and what is each part for |
troposphere : bottom layer , causes weather , gases swirl around . contains most mass stratosphere : contain ozone layer , temp increases , from flat layers mesosphere : temp. decreases thermosphere : temp. increases exosphere : lowest density
