The experimenting stage, since the scientist would need to record his or her data on a chart
Answer:
C. Heat and Pressure
Explanation:
The arrow which is labeled A points from igneous rock to metamorphic rock.
There are three types of Rocks:
1. Igneous Rock
2. Metamorphic Rock
3. Sedimentary Rock
Rock cycle:
Rock cycle is the process that describes the transition between these three types of rocks. Each type has its own form and its own equilibrium condition. The rock type alters when it is pushed out of its equilibrium conditions.
Transition of Igneous rock to Metamorphic rock:
Igneous rock forms when magma cools down. The transition of Igneous Rock to Metamorphic Rock is a result of a process called Metamorphism. Metamorphism is the alteration in the structure of rock as a result of certain heat and pressure conditions. Inside Earth heat comes from pressure. Heat with pressure does not melt the rock but it bakes the rock. Baking is not melting but it changes the shape of the rock while it is still solid. It actually forms crystals. Because the rock changes its structure, it is called Metamorphic Rock.
Answer:
19 cm sq
Explanation:
you have to count one full and half area occupied by leaf in each box, then you have to multiply with 1 cm sq.
Answer:
2.27kg
Explanation:
The Potential energy gained = Force gravity× Height
Force gravity on the ball is GPE/ height
56.8/2.5=22.72N
the mass = 22.72/10= 2.27kg
centripetal acceleration can be determined using the following equation;
a = v² / r
a= centripetal acceleration
v = velocity
r = radius
substituting the values in the equation,
a = (300 m/s)*(300m/s) / (1.85 *1000) m
= 48.64 ms-²
