How would conditions on Earth be different if its axis did not tilt? *
A There would be no seasons.
B There would be no years.
C There would be no temperature
D The equator would not be as warm in winter.

Answers

If the earth didn't have a tilt, we wouldn't have seasons. Instead, the environment would be unchanging, and the temperature would vary upon latitude. Equatorial regions would be constantly hot and humid, and polar regions would always be cold. There would no variability to the climate as the year progresses.

I think the answer is C

Sedimentary rocks begin forming when existing rocks are worn away by wind and rain in a process called weathering. Weathering breaks rock into smaller pieces called sediment. Erosion is the removal and movement of sediment. Weathering and erosion happen slowly, over thousands and even millions of years. Eventually, layers of sediment are deposited on top of one another and pressed together. Sedimentary rock is formed when sediment sticks together after liquid is squeezed out. Sometimes, fossils get trapped between sediment layers.

The sediment of sedimentary rocks can range in size from a grain of sand to a shell or pebble. The name of the rock that’s created depends on the sediment that it’s made of. For example, shale is made of clay. Conglomerate is made of coarse sediment the size of small pebbles. The sediments of limestone are small shells.

Which of the following is an example of erosion?

A
Wind breaking down an existing rock into smaller pieces.

B
Layers of sediment pressed and sticking together.

C
Small shells being moved by water to the shore.

D
Animal fossils getting trapped between sediment layers.

Answers

Answer:

I think the answer is C

Explanation:

Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment. Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment.

It would be b because layers of rocks is sedimentary “layers of rock”

Add all the net forces together and that number will be your new net force and that’s how it done

If the arrows are in the same direction then you have to add them. If the arrows are in opposite you have to take away. For example for question 5 8-4=4 so thE net force will be 4 and the arrow will be left as 8N is bigger. For question 4 they are in the same direction so you add them it will be 9N to the right. For question 3 they are in opposite so it will be 0 and both arrows are equal so the net force is 0 and then object is stationary

A force is simple a ___________ or a _______________.

The SI unit for force is ____________________.

When the net force on an object is not zero newton, the forces are said to be _______________________________.

When 2 forces act in opposite directions, you __________________ (add, subtract) the forces.

Answers

Answer: a force is simply a push or pull.

The SI unit for force is Newton(N) or kgm/s2

When the net force on an object is not zero the forces are said to be unbalanced since they do not cancel out each other .

When two forces act in opposite directions we substract the forces in order to get the resultant force acting on the object.
