The California miners found silver in the blue sand and sticky soil which caused problems because they were primarily looking for gold and there was a lot of silver in the way.
A slow change such as continents moving will create differences in ecosystems. This is also the same effect caused by a rapid change such a meteorite striking earth. These two phenomena will create diversity and different living conditions. The slow change however, will give organisms time to adopt giving them a good chance of survival unlike a rapid change which will give most, if not all, organisms little chance to survive.

Answer:
4. Solar energy makes food grow. By eating the food we can create a store of chemical energy inside us. We can use this stored energy to do work like wind an alarm clock. The clock now has potential energy.
5. You pedaling the bike is transforming chemical energy, supplied by the breakdown of the food you eat, into mechanical energy to turn the pedals. The chemical energy is potential and the mechanical energy is kinetic
6. As a pendulum swings, its potential energy converts to kinetic and back to potential. Recall the concept of conservation of energy—that energy may change its form, but have no net change to the amount of energy.
7. Renewable resources def: ways to generate energy from (theoretically) unlimited natural resources. These resources are either available with no time limit or replenish more quickly than the rate at which they are consumed
Examples of Renewable resources
• Solar energy.
• Wind energy.
• Geothermal energy.
• Hydropower.
• Bioenergy.
Nonrenewable resources def: A non-renewable resource is a natural resource that cannot be readily replaced by natural means at a quick enough pace to keep up with consumption. An example is carbon-based fossil fuel. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas
