Study Questions from Chapters 1 and 2 and The Nature of Science
The test on ____________ will may contain multiple choice, diagrams, short answer or matching. These questions will give you an idea of what type of things you need to study.
The solar system began as a 10 billion Km wide cloud of gas and dust
The outer core is liquid iron and nickel.
Only into the crust, no further.
An oblate spheroid due to the rotation of earth on its axis
- The shadow of earth on the moon during a lunar eclipse is spherical
- The position of the stars rotate slowly during the course of the night
- The mast of a ship will appear first over the horizon when a ship is traveling towards you.
Below 20 meters depth temperature will rise 1 degree C for every 40 meter you travel down. Above 20 meters the temperature will cool as you go down.
An educated guess
See page 10 in your book.
No, because of the shape of the earth. At the poles a person is closer to the ceter of gravity, therefore, weighs more. At the equator a person is further from the center of gravity, therefore, weighing less.
The separation of items into groups of a common attribute. Earths layers are differentiated or layered due to different densities.
Volcanoes gave out gases which condensed and fell as rain.
Silicon and oxygen
Know the Proto-Planet Hypothesis all of it!
- All planets revolve around the sun in the same direction
- Most planets revolve around the sun on the same axis
- There is still left over material in the solar system (meteors and comets)
Density is how much matter is packed into a given amount of space. Density = mass/volume
Distance between 2 points and the angle between the 2 points
Gasses entered the air due to volcanoes and fissures in the earth. These gases condensed and carbon dioxide was introduced. Green plants began to grow and with the help of the sunlight and photosynthesis, free oxygen was introduced. These gases built up to what they are today.
Poles are flattened and the equator bulges out.
