How can you tell a concave slope on your map?
How can you tell a concave slope on your map? Concave: Contour lines showing a concave slope on a map will be closely spaced at the top of the terrain feature and widely spaced at the bottom. Bushwalkers going up the slope will find the terrain increasingly steep and challenging. What are the 10 terrain […]
What are the 3 major layers of the geosphere?
What are the 3 major layers of the geosphere? The Earth’s geosphere is divided into three chemical sections: The crust, composed almost entirely of light elements, like silicon. The mantle, which is 68% of the Earth’s mass. The core, the innermost layer; it is composed of very dense elements, such as nickel and iron. What […]
What are the three components of an electrical circuit?
What are the three components of an electrical circuit? Electric circuits An electric circuit has three parts: An energy source – like a battery or mains power. An energy receiver – like a lightbulb. An energy pathway – like a wire. Why you should not waste electricity? We should not waste electricity because it is […]

What is the half-life of AU 198?
What is the half-life of AU 198? 2.697 days How do you calculate the half-life of sodium 24? Notice that the time period between each of the yellow crosses is 15 hours. This tells us that the count rate of Sodium-24 halves every 15 hours. In other words, the activity of Sodium-24 is halved every […]

What happens when the two atoms are too close?
What happens when the two atoms are too close? Covalent bonds If two atoms get close enough together then the electrons of each atom will be attracted to both nuclii. If the atoms get two close then the nuclii will repell each other. Single sided arrows represent attraction. Double sided arrows represent repulsion. What happens […]
Why is there no Coriolis force at the equator?
Why is there no Coriolis force at the equator? Because there is no turning of the surface of the Earth (sense of rotation) underneath a horizontally and freely moving object at the equator, there is no curving of the object’s path as measured relative to Earth’s surface. The object’s path is straight, that is, there […]
