L2 Flashcards
The smallest planet and closet to the sun
Mercury
The hottest planet in the solar system
Venus
The only planet with liquid
Earth
Really dusty and cold with a thin atmosphere
Mars
twice the size of the other planets so they call me giant
jupiter
Surrounded by a series of rings
Saturn
Rotate on a tilt planet
uranus
the smallest giant and further from the sun
Neptune
WHAT MAKES OUR PLANET THE ONLY LIVING PLANET IN THE SOLAR SYSTEM?
Right distance to the sun
The presence of an atmosphere
Right amount of gravity
The presence of oxygen
The presence of liquid water
Generation of internal heat.
is the thin gaseous layer that envelopes the lithosphere.
ATMOSPHERE
The present atmosphere is composed of ______, _____, ___-, and trace amount of other gases.
78% nitrogen (N), 21% oxygen (O2), 0.9% argon
One of the most important processes by which the heat on the Earth’s surface is redistributed is through _____.
atmospheric circulation.
There is also a constant exchange of heat and moisture between the atmosphere and the hydrosphere through the ____.
hydrologic cycle
Layers of the ATMOSPHERE
Exosphere
thermosphere
mesosphere
stratosphere
troposphere
is the closest to the Earth’s surface and is the layer in which we live. It extends from the surface up to around 10-15 km and is characterized by temperatures that decrease with altitude.
troposphere
examples of troposphere
Hot air balloon and airplane
extends from the top of the troposphere up to around 50 km.
This layer is characterized by temperatures that increase with altitude due to the presence of ozone.
Stratosphere
example of stratosphere
Radiosonde
extends from the top of the stratosphere up to around 85 km. This layer is characterized by temperatures that decrease with altitude and is the coldest layer in the atmosphere
mesosphere
example of mesosphere
meteors and meteorological racket
is characterized by temperatures that increase with altitude due to the presence of charged particles that absorb energy from the sun.
thermosphere
example of thermosphere
aurora lights
is the outermost layer of Earth’s atmosphere.
It is an important part of the Earth’s atmosphere, as it provides protection from harmful radiation from the Sun and other sources.
exosphere
example of exosphere
spaceship and satellite
About 70% of the Earth is covered with liquid water _____and much of it is in the form of ocean water.
(hydrosphere)
Only 3% of Earth’s water is ____: two-thirds are in the form of ____, and the remaining one-third ____,___ and __-
fresh, ice, streams, lakes, and groundwater.
WATER CYCLE
EVAPORATION
CONDENSATION
PRECIPITATION
TRANSPIRATION
SURFACE RUN OFF
INFILTRATION
includes the rocks of the crust and mantle, the metallic liquid outer core, and the solid metallic inner core.
LITHOSPHERE
Layers of the Earth
Crust
Mantle
Core
outermost layer
thinnest layer (5-70km thick)
where we live
CRUST
2 Types of Crust
Continental Crust and Oceanic Crust
dry land,
Made up of granite,
less dense
Continental Crust
ocean floor,
Basalt,
thinner than cont. crust
but more dense
Oceanic Crust
thickest layer (2900km thick)
1600-4000 F
66% of earth’s mass
flowing
Composition:
Molten rock
Magma
MANTLE
two parts of core
outer core and inner core
Liquid iron and nickel that’s spinning
Outer Core
Solid iron and nickel
Solid because of all the pressure of the rest of the Earth surrounding it.
Inner Core
is the set of all life forms on Earth
biosphere
It covers all ecosystems—from the soil to the rainforest, from mangroves to coral reefs, and from the plankton-rich ocean surface to the deep sea.
