The correct answer are: C. heat, and E. pressure.
All metamorphic rocks need this two factors so that they can be formed from either igneous or sedimentary rocks. The metamorphic rocks form deep into the ground where the pressure is higher and the temperature is higher as well, the deeper they form the bigger the pressure and temperature they experience. According to how big of a temperature and how big of a pressure the rocks have been exposed it determines into what type of metamorphic rocks they will turn into, and according to that what kind of a texture and appearance will they have. The amount of time of exposure to heat and pressure is also key to the type and quality of the metamorphic rocks.
<h2>Answer: False</h2>
The longest river in the world in is the Amazon, located in South America, with a length of 6800 kilometers, compared to 6695 of the Nile River.
It is understandable that for a long time it was believed that it was the Nile. However, a few years ago the Brazilian Institute of Geography and Statistics published an investigation claiming that the Amazon is the longest river in the world.
On the other hand, the Sahara Desert itself is the largest (warm) desert in the world, <u>but</u> the Antartic Desert occupies the first place with an area of 
compared to 
of the Sahara.
Taking into account that the definition of desert is a place with very little or no rainfall in the year.
<h2>Therefore this is false.</h2>
It's the picture of the Atlantic ocean. On average, the Atlantic Ocean is growing at a rate of about 2.5 cm/year.
So,
1. Since 2000, it grows about (2018-2000) x 2.5 = 45cm
2.( 2018 - 1492) x 2.5 = 1315 cm
3. 200 x 2.5 = 500 cm
4. The <span> Atlantic begin forming since mesozoic era</span>
Answer:
volcanoes are formed by eruptions of lava and ash when magma rises through cracks or weak spots
From rocks being added together over time
