Hydrogen Gas |
|
|
What gas is produced when acids react with carbonates? |
Carbon Dioxide |
|
|
What is litmus paper? |
Paper stained with litmus which is used to indicate the acidity or alkalinity of a substance. Blue litmus paper turns red under acid conditions, and red litmus paper turns blue under alkaline conditions. |
|
|
What does corrosive mean? |
Destroy and damage other substances with which it comes into contact. |
|
|
On which axis of a graph is the dependant variable plotted? |

If a reaction needs heat input to start it, where is the word heat put in the equation? |
On the left side of the equation, because it is a reactant. |
|
|
What happens at plate boundaries? |
They either diverge, converge or transform. |
|
|
What happens at a divergent plate boundary? |
The plates pull apart, which then allows magma from the mantle to rise. |
|
|
What happens at a convergent plate boundary? |
1. The oceanic crust gets punched into the continental crust, the oceanic crust is more dense than the continental crust forcing it under the continental crust. 2. The continental crust pushes against the continental crust, pushing against each other, forcing them upwards and creating a mountain. |
|
|
What happens at a transform plate boundary? |
The plates slide past each other, causing tremors and earthquakes. |
|
|
Explain the tectonics plate theory. |
-Approximately 30 plates -The plates move on a layer of molten rock in the mantle -The plates move becauseheat causes the partially molten rock in the mantleto expand and rise towards the surface. It spreadsout, cools and falls back under the force of gravity.This creates a convection current that keeps the platesmoving slowly. |

|
|
What is a vulcanologist? |
