Explanation:
Pangea was a super-continent on the earth which formed about 330 million years ago during the Paleozoic and began breaking up during the early Mesozoic, about 175 million years ago.
Most of the present day continents formed as a result of the separation of the Pangea in the early Mesozoic.
The first scientist to propose the existence of this super-continent was Alfred Wegener in 1912. He suggested the continental drift hypothesis to explain the separation of the land masses.
Today, the theory has been revised to the theory of plate tectonics which provides a better mechanism to understand the drifting of the continents.
Here are some of the evidences to support the existence of Pangea;
This among many other evidences underscores the existence of a supercontinent called Pangea.
b. bedrock.
c. aggregate.
d. pollen.
By the angle addition postulate and substitution, the m∠POS would be - 65⁰
Angle Addition Postulate is the measure of the larger angle is the sum of the measures of the two smaller angles.
Substitution postulate states that a quantity may be substituted for its equal in any expression.
Then substitute the angle measurements into the resulting equation to find m∠POS
m∠POQ + m∠QOR = m∠POR (by angle addition)
m∠POR + m∠ROS = m∠POS (by substitution)
Solution:
m∠POS = m∠POQ + m∠QOR + m∠ROS
= 19° + 31° + 15°
= 65°
Thus, the m∠POS would be - 65° by the angle addition postulate and substitution postulate.

Answer:
65
Explanation:
Add 19, 31, 15 =65
65=POS
False
b. They measure distance north and south of the prime meridian.
c. They measure distance east and west of the prime meridian.
d. They measure distance north and south of the equator.
They measure the distance north and south of the prime meridian is the statement accurately describes lines of latitude, also called parallels, on a map. Hence, option B is correct.
Latitude lines, often called parallels, are imaginary lines that divide the world in half. They run from east to west, yet they calculate your distance north or south.
The equator is the most well-known parallel. At 0 degrees latitude, it evenly divides the Earth into the Northern and Southern hemispheres. Meridians are imaginary lines that divide the world; they are also referred to as lines of longitude.
Running from north to south, they gauge the distance either east or west, from pole to pole. The prime meridian travels through Greenwich, England, at a longitude of 0 degrees.
Thus, option B is correct.

They are older than the Appalachian Mountains
They are shorter than the Appalachian Mountains
They are younger than the Appalachian Mountains
They are taller than the Appalachian Mountains
The statements about the Rocky Mountains are true
The Rocky Mountains are known for their tall peaks that are surrounded by valleys, glaciers, and dense forests. More than just hills and mountains can be found there. Wide-open grasslands and running rivers are surrounded by hilly slopes.
The Appalachians are considerably older than the Rocky Mountains. The Appalachian Mountains were formed over the last 480 million years whereas the Rocky mountains began forming 60 million years ago.
The Cordillarians' eastern edge mountain range is the Rocky Mountains. National parks of great significance can be found in the mountain range.

Answer: They are younger than the Appalachian mountains
They are taller than the Appalachian mountains
Explanation:
The Appalachian mountains highest peak is about 6,684 feet while the Rocky mountains highest peak is 14,440 feet
The Appalachian mountains are 480 million years old while the Rocky mountains are only about 300 million years old
