6. You design an experiment in which you investigate it different types of fertilize atteet tomato plant height. You prepare 4 plots of soil, all containing tomato plants. To the first
plot, you add a potassium fertilizer. To the second pict, you add a nitrogen fertilitet To
the third plot, you add a phosphate fertizer. You do not add any fertilizer to the fourth
plot You eventually gather data by measuring the height of each tomato plant,
B. What is the independent variable?
C. What is the dependent variable?
D. What type of data are you gathering qualitative or quantitative!

A where is question A?

B types of fertilizer

C plant height

D quantitative

the control is no fertilizer

& what is the null hypothesis?

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
