Answer: b) earthquake activity
Options:
a) earth's density
b) earthquake activity
c) volcanic activity
d) atmospheric composition
Explanation:
Earthquake activity
: Seismic waves are responsible for the earth trembling during earthquakes. An earthquake occurs as seismic waves travel through the interior of Earth’s surface. A seismograph measures the characteristics of these waves such as how fast they travel as well as their strength.
By studying these attributes in different places, scientists come to understand the makeup of earth’s internal structure. The type of seismic waves most important to this study are body waves which travel through the earth’s interior
.
The <em>Mid-Atlantic Ridge </em>is composed of the youngest crustal bedrock.
<h2><u>Answer:</u></h2>
For the right triangle to be given in name of three letters such as this, the right angle is most likely to be in the center, in this case letter K. To determine the common trigonometric properties of a certain angle we may use of the mnemonics SOH - CAH - TOA.
sin angle = opposite side / hypotenuse
cosine angle = adjacent side / hypotenuse
tangent angle = opposite side / adjacent side
If we let small letter j, k, and l be the sides opposite to angles J, K, and L, respectively. Then, the cos (L) will be,
cos (L) = j/k
There are 8 planets in our solar system
Answer:
Explanation:
Catalytic converters are used as an exhaust emission control device and are used to remove toxic gases and products by catalyzing the redox reactions.
The Corporate Average Fuel Efficiency (CAFE) standards were set of rules enacted in the USA to increase the efficiency of fuel engines and hence to reduce the emission rates .
The ethanol as compared to the conventional gasoline emits 50 per cent or lesser greenhouse gases to the environment .
