Answer:
Christianity
Explanation:
Biological weathering is the weakening and subsequent disintegration of rock by plants, animals and microbes.
this correct answer is true
(1) Holocene
(2) Pleistocene
(3) Oligocene
(4) Eocene
Answer:
Grasses evolved around 40 million years go, that is in the Paleogene period.
Paleogene can be divided into Oligocene, Eocene and Paleocene.
40 Millions years ago falls into Eocene - this is the correct answer.
Grasses actually appeared rather late, and other plants, including ones with flowers appeared earlier.
b. north
c. east
d. south
Answer:
b. north with a lat long of 45°24′N 75°40′W
Explanation:
The submarine was initially 3500 meters below sea level and then ascends 1200 meters, so its new position would be 2300 meters below sea level.
Sea level is considered the reference point for measuring the depth of objects underwater. When the submarine was initially at 3500 meters below sea level, it means it was submerged 3500 meters beneath the surface of the water.
When the submarine ascends by 1200 meters, it moves closer to the surface. The new position is calculated by subtracting the ascent (1200 meters) from the initial depth (3500 meters):
3500 meters - 1200 meters = 2300 meters
So, the submarine's new position after ascending 1200 meters is 2300 meters below sea level.
To learn more about Sea Level:
The submarine's new position is 4700m below sea level.
To find the submarine's new position, we need to add the ascent distance to the initial depth. The submarine starts at a depth of 3500m below sea level and ascends 1200m.
To calculate the new position, we add the ascent distance to the initial depth:
3500m + 1200m = 4700m
Therefore, the submarine's new position is 4700m below sea level.

A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, lava spews from long fissures and geysers spurt superheated water. Frequent earthquakes strike along the rift. Beneath the rift, magma—molten rock—rises from the mantle. It oozes up into the gap and hardens into solid rock, forming new crust on the torn edges of the plates. Magma from the mantle solidifies into basalt, a dark, dense rock that underlies the ocean floor. Thus at divergent boundaries, oceanic crust, made of basalt, is created.
When two plates come together, it is known as a convergent boundary. The impact of the two colliding plates buckles the edge of one or both plates up into a rugged mountain range, and sometimes bends the other down into a deep seafloor trench. A chain of volcanoes often forms parallel to the boundary, to the mountain range, and to the trench. Powerful earthquakes shake a wide area on both sides of the boundary.
If one of the colliding plates is topped with oceanic crust, it is forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into new crust. Magma formed from melting plates solidifies into granite, a light colored, low-density rock that makes up the continents. Thus at convergent boundaries, continental crust, made of granite, is created, and oceanic crust is destroyed.
