A volcano with an empty magma chamber would be called a caldera
Explanation: During certain types of explosive eruptions, a volcano's magma chamber may empty enough for an area above it to subside, forming a type of larger depression known as a caldera.
A "projection" is a way of displaying the 3-D Earth in a 2-D form <em>(C)</em> ... like on a piece of paper.
There are many different map projections. Each one has advantages and disadvantages. It's not possible to correctly reproduce all the details of a globe surface on a flat piece of paper. Something's gotta give.
Answer:
Mechanical energy = 145 Joules
Explanation:
Given the following data;
Kinetic energy = 115J
Gravitational Potential energy = 30J
To find the mechanical energy;
Mechanical energy = kinetic energy + gravitational potential energy
Substituting into the equation, we have
Mechanical energy = 115 + 30
<em>Mechanical energy = 145 Joules. </em>
Mechanical energy can be defined as the ability (capacity) to do work. The two (2) main types of mechanical energy are;
<em>a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.</em>
<em>b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.</em>
Answer:
Coal is called a fossil fuel because it was made from plants that were once alive! Since coal comes from plants, and plants get their energy from the sun, the energy in coal also came from the sun.
The release of greenhouse gases damages the ozone layer, (the layer protecting us from the suns rays) exposing the planet to the suns harmful radiation rays, increasing the temperature by a small amount each year
