Answer:the alternate rising and falling of the sea, usually twice in each lunar day at a particular place, due to the attraction of the moon and sun.
"the changing patterns of the tides" Witch makes the high tide, and low tide
Explanation:
Alkanes are hydrocarbons with only single bonds between the carbon atoms, therefore, they do not contain any double bonds.
In chemistry, an alkane is a type of hydrocarbon where all of the carbon-carbon bonds are single bonds, meaning they share just one pair of electrons. Double bonds share two pairs of electrons and are typically found in alkenes, a different type of hydrocarbon. Therefore, an alkane does not have any double bonds.

Explanation:
Combustion is an exothermic reaction which involves the burning of a compound in the presence of oxygen. Combustion is a very useful life process as it produces heat and light.
For a complete combustion reaction to occur, the compound must be burnt over excess oxygen. The product is usually carbondioxide and water with release of some particulate matter.
In incomplete combustion, there is deficiency of oxygen. Here, oxygen becomes the limiting agent and it drives the reaction to an end. Incomplete combustion is always accompanied with the production of poisonous carbon monoxide and Carbon. We see incomplete combustion when smoke forms or when burning is accompanied by production of soot.
What makes a combustive process complete or not is the availability of oxygen gas for the reaction.
B. specific heat
C. freezing point
D. solubility
b.igneous rock is eroded to from metamorphic rock.
c.metamorphic rock melts to from sedimentary rock.
d.none ofthe above.
In the rock cycle, sedimentary rock is heated and a squeezed to from metamorphic rock.
They are the types of rocks which are formed as a result of accumulation of minerals or organic particles at the surface of the earth.Sedimentation is the name given to a collective process which cause the particles to settle.
The study of sedimentary rocks is useful in civil engineering and as important sources of coal, fossil fuels and ores.The color of sedimentary rock is often determined by iron content and sometimes due to the presence of organic matter.
They are classified based on origin in to 4 types which are clastic, biochemical ,chemical and other sedimentary rocks.While based on composition they are classified as siliciclastic,carbonate ,evaporite,organic rich,siliceous ,iron-rich and phosphatic sedimentary rocks.
