The correct answer is B. 50ft
Explanation
This image is a contour line in which each line represents a cut of the terrain at a specific height, you can see that the first line has a number zero, the third line has a number 100ft and the sixth line has a number 200ft. Therefore, it can be stated that each line represents an ascent of 50 ft in height because the interval corresponds to 50 ft in height. So, line 1, 0 ft; line 2, 50 ft; line 3, 100 ft; line 4, 150 ft; line 5, 200 ft; and so on. So the correct answer is B. 50ft.
Metamorphism of pre-existing sedimentary or igneous rocks occurs by heat from nearby magma called an igneous intrusion.
Answer: Option C
<u>Explanation:</u>
Contact metamorphism occurs when the hot igneous rock thrusts into some some other rock which exists previously. Then the pre-existing rock is baked by heat and during this process no additional pressure is added and this leads to the change in the mineral structure of the rock. Contact metamorphism is occurred only with heat and not by adding any additional pressure on the rock.
Middle America is an isthmus that connects North and South America.
Explanation:
Middle America, or more commonly referred to as Central America, is actually part of North America. It represents the southernmost part of the continent, but is often put as a separate region because of its shape which makes it distinct from the rest of the continent. In fact, it can be said that Middle America is an isthmus that is connecting the two large continental masses of North America and South America.
This region's northern boundary is still disputable, and it varies from author to author, though in general it is borders of Belize and Guatemala that are taken as the northernmost parts. On the south it is Colombia's border, on the east it is the Caribbean Sea, while on the west is the Pacific Ocean. As a region, because of the multiple tectonic plate boundaries, Middle America is geologically highly active, with volcanic and earthquake activities being relatively common.
The countries that comprise this region are:
- Guatemala
- Belize
- El Salvador
- Nicaragua
- Honduras
- Costa Rica
- Panama
