Answer:
b. each has its own geologic history.
Explanation:
An ocean is a body of salt water which covers approximately 70% of the Earth's surface. About 97% of the Earth's water is comprised of ocean and as such it is the most prominent and defined feature of the Earth. There are basically four (4) categories of an oceanic basin and these are;
<em>1. The Pacific ocean. </em>
<em>2. The Artic ocean. </em>
<em>3. The Atlantic ocean. </em>
<em>4. The Indian ocean. </em>
On the other hand, Continents can be defined as very large landmasses or area of land typically surrounded and separated by water. It is divided into seven (7) main categories and these are;
<em>1. Africa. </em>
<em>2. Asia. </em>
<em>3. Antarctica. </em>
<em>4. South America. </em>
<em>5. North America. </em>
<em>6. Australia. </em>
<em>7. Europe. </em>
Continents differ in appearance from ocean basins because each has its own geologic history. Thus, a continent is less denser and comprise of a thick granite material while an oceanic basin is dense and an older basalt.
When a continent is compared with an oceanic crust, it was discovered that the continental crust is lighter in colour than the oceanic crust.
Airborne fragments<span> of lava, called tephra, are ejected from a single vent. The lava cools rapidly and builds up around the vent, forming a crater at the summit. Cinder cone volcanoes are fairly small, generally only about 300 feet (91 meters) tall and not rising more than 1,200 feet (366 meters).</span>
Answer:
the pressure exerted by the weight of the atmosphere, which at sea level has a mean value of 101,325 pascals (roughly 14.6959 pounds per square inch).
Answer:
Answered
Explanation:
we can very well understand this question with the help of Psychometric chart as the amount of vapor in the atmosphere decrease the vapor pressure(pressure exerted by the vapor depends upon the amount of vapor) will surely decrease and dew point temperature must also decrease from the psychometric chart ( since both relative humidity and dew point temperature are horizontal lines on psychometric chart. Hence, option B and C are correct
