Which explanations provide support for continental drift theory? Check all that apply.
Dinosaurs lived on many continents.
Coal fields match up across continents.
Tropical plant fossils were found in Arctic areas.
Similar rock types are found across continents.
Evidence of glaciers can be found in South Africa.
Coal fields match up across continents.

Evidence of glaciers can be found in South Africa.
<h3><u>
Explanation:</u></h3>
The way the continents on the earth shifts its position is explained by the Continental drift theory. Alfred Wegener was the one who fist proposed this theory in 1912. This theory also explains how similar rocks are formed on the different continents and also the reason why some of the animal and plant fossils looks similar.
The evidences that supports the continental drift theory can be Coal fields match up across continents. Fossils of Glossopteris supports the theory of continental drift with coal fields and coastlines
. The land features, climate changes are some of the evidences that also supports the theory of continental drift.The evidences of the glaciers that can be found in South Africa also supports the explanation of the continental drift.
When plates pull apart underwater, the hot magma instantly rises and spreads itself to form a new ocean floor.Under a continent, the crust splits open to allow magma out. The magma might make its way slowly to the surface, creating warm areas and hot springs or geysers as surface water meets it.<span>Or the magma might explode, bringing into existence a new volcano where there was only cool earth before.</span>
Constellations are based off of many Greek and Roman fables. Many of their gods and beliefs are pictured in the stars, which is where we get most of our constellations. Hope this helps!
Answer:
v = √(2gh)
Explanation:
Given:
Δy = h
v₀ = 0
a = g
Find: v
v² = v₀² + 2aΔy
v² = (0)² + 2gh
v = √(2gh)
You can also prove this with conservation of energy.
PE = KE
mgh = ½mv²
v = √(2gh)
In order to calculate the unknown reaction force, we need to know that the sum of forces pointing down is equal the sum of the forces pointing up, so all forces will be in equilibrium.
So we have:
