earth science
collection of different but related disciplines that together give us a unique
understanding of the world in which we live and its context in space
earth science disciplines
1. hydrology
2. geology
3. oceanography
4. meteorology
5. astronomy
Interactive components of the Earth
1. hydrosphere
2. geosphere
3. biosphere
4. atmosphere
geology
the study of the earth, specifically rocks and the planet's crust
hydrology
Study of water
oceanography
Study of Earth's oceans
meteorology
The study of the earth's atmosphere in relation to weather and climate
astronomy
study of the universe
common views about Earth's history
1. Young-Earth creation
2. Old-Earth creation
3. theistic evolution
4. naturalistic evolution
Young-Earth creation
oldest and most strongly supported view
1. all of God's work of creation was accomplished in a six-rotational day period a few
thousands of years ago
2. God directly and miraculously created organisms that have since diversified
3. humans were created separately and miraculously apart from others to be rulers over
creation
4. global Flood destroyed the world and its inhabitants at the time of Noah; responsible
for the majority of sedimentary rocks and fossils found on the planet's surface
Old-Earth creation
1. Earth is ancient (4.55 billion years)
2. creation by God was over many millions or billions of years
3. humans were new and miraculous creations by God
4. Noah's flood was a local rather than global event
, Theistic evolution
1. also called "evolutionary creation"
2. God created life using only evolution
3. all of life is genetically connected (humans share ancestry with apes)
4. Noah's flood was either local or a non-historical myth
Naturalistic Evolution
1. non-theistic view, with no discernable role for God
2. all of life is genetically connected
3. dominant view among scientists today
4. genetic continuity between man and non-human animals
there is no singular scientific method
true
which two views agree with naturalistic evolution?
Old-Earth creation and theistic evolution
what does it mean to do good science?
leads us to great discoveries, advances, and insights
basic characteristics of scientific method
observation - prompt questions - think of hypothesis or predictions - test hypothesis -
evaluate success
natural sciences can be divided into two categories
1. experimental science
2. historical science
experimental science
what we most often think of; controlled conditions in which hypothesis is tested in
repeatable fashion
historical science
an event that cannot be repeated, seek to discover events that occurred one time in the
past
Brand's model of science/religious interactions
Brand claims that science and religion have their own sets of rules and principles but
also claims there is an interface between them, where one domain can inform or benefit
the other
atmosphere
outermost component of Earth; collection of Earth's gases
what gases make up our atmosphere
nitrogen and oxygen
how much water of the hydrosphere are in oceans?
97%
how much water of the hydrosphere is in glaciers?
>2%
thickness of the crust
5-70 km
depth to crust
670 km
depth to lower mantle
2,890 km
