Science 1
Is the rate at which Energy is transformed from one form to another.
How do you call the area of magnetic force arround a magnet?
Magnetic Field
What is Motion?
Is the state in which one object's distance from another changing.
What does the Topography of an area Include?
Elevation, Relief and Landform
Explain what is Map Projection:
Is a frameworkof lines that helps to transfer points on Earth's three dimensional surface onto a flat map
What is a short circuit?
Is a connection that allows current to take the path of least resistance.
How do magnetic field lines work?
They spread out from one pole, curve arround the magnet and return to the other pole.
Define Magnetism:
The force of attraction or repulsion of magnetic materials.
What is an Elevation?
The height above sea level of a point on Earth's surface
Define Wathering:
The process that breaks down Rocks and other substances
Define what is a Magnet:
Any material that attracts iron and materials that contain iron
What is electromagnetism?
Is the relationship between elecrticity an magnetism
What does an electric motor do?
Tranforms electrical energy into mechaical energy
Explain what is a Relief:
The difference in elevation between the highest and lowest parts of an area
What is Erosion?
The process of wearing down and carrying away Rocks
What is magnetism?
The attraction or repulsion of magnetic materials.
What are the characteristics of Selenoids and Electromangets?
Bothe use electric current and coil wires to produce magnetic fields
What is a conductor?
A material that conducts heat and electricity well
What is a Landform?
Is a feature of Topography such as a hill or Valley
What is the composition of Soil?
Mixture of rock particles, minerals, decayed organic material, water and air.
Explain how the attraction of Magnetic Poles works?
Magnetic poles that are unlike attract each other and Magnetic Poles that are alike repel each other.
Define what is a Selenoid:
A coil of wire with a current
Define Direct current:
Are charges that flow in only one directionin a circuit
Plains, Mountains, Plateaus and Landform Regions
