1. SCIENCE- Name the 3 main layers of the earth.

Atmosphere. Ground and Dirt

Conficous,Minadous and Fenerous

Outer, Inner and Core

Crust, Mantle and Core

Crust, Inner Core and Outer Core

The correct answer is "Crust, Mantle and Core." The Earth is composed of several layers, with the crust being the outermost layer. The crust is the thinnest layer and is made up of solid rock. Beneath the crust is the mantle, which is a thick layer of semi-solid rock. The core is the innermost layer and is divided into the inner core and the outer core. The inner core is solid, while the outer core is liquid. These three layers play a crucial role in the structure and dynamics of the Earth.

3. ENGLISH- What must any piece of writing have?

An Author

A Beginning a Middle and a End

Sentences

A Title

Correct spelling

A piece of writing must have a beginning, a middle, and an end in order to be considered complete and coherent. These three components help to structure the writing and provide a clear flow of ideas or information. Without a beginning, the reader may feel lost or confused about the context or purpose of the writing. The middle section develops and expands on the main ideas, providing supporting details or arguments. Finally, the end brings closure to the writing, summarizing the main points or offering a conclusion. Overall, having a beginning, a middle, and an end helps to create a well-rounded and engaging piece of writing.

4. MATHS- Work out the area of a triangle L=4cm and W=30cm

15cm

120cm

60cm

220cm

50cm

The area of a triangle is calculated by multiplying the length of the base by the height and dividing the result by 2. In this case, the length of the base is given as 4cm and the width (which is actually the height in this case) is given as 30cm. So, the area of the triangle can be calculated as (4cm * 30cm) / 2 = 120cm². Therefore, the correct answer is 120cm.
