They are formed when the rock is still in it's MOLTEN state (liquid-like) and then when it cools, it hardens. The lasting appearance is that of solid rock looking like a bunch of folds on your grandfather's forehead.

What is the fold and what's the oldest rock where is are in the center of the fold?

A fold is a geological structure where rock layers are bent or curved due to tectonic forces, typically resulting in the formation of ridges and valleys. The oldest rock in the center of a fold is often referred to as the "nucleus" or "core" of the fold and is usually a type of metamorphic or igneous rock that has undergone significant geological processes. In many cases, this oldest rock is referred to as the "axial" or "central" part of the fold. The specific age of the oldest rock can vary widely depending on the geological context and location of the fold.


Can you fold checks without causing any damage to them?

Yes, you can fold checks without causing damage as long as you fold them carefully along the crease lines and avoid folding them too tightly or forcefully. It is recommended to use a gentle touch when folding checks to prevent any tearing or creasing.


How you will find center of a paper without using any instruments?

If the paper is regular in shape (a rectangle, for instance), fold it in half so that opposite edges meet. Then fold it in half the other way. The two fold lines will cross at the center.


When does a geological fold occur?

A geological fold occurs when a flat surface like sedimentary rock are deformed and bent. It can occur through natural stress, water pressure or man made causes and engineering.

How can you write a lot of info on one notecard without cheating?

You can write small so that you can get more information on the card. To keep information separated on the card, you can fold the card and write different subjects within the fold lines.


What are lines of semmetry?

If you canfold something in half and the two sides are identical then the fold is a line of symmetry. A circle has an infinite lines of symmetry because you can fold it in infinite places and it will always be the same. An oval has two - you can fold it the long way or the short way.


What are symmetry lines look like?

Something that you can fold and its equal....


What is a fold that is tilted beyond 90 degrees?

A fold that is tilted beyond 90 degrees is known as an "overturned fold." In this type of fold, the layers of rock are bent to such an extent that one limb of the fold has flipped over, resulting in a steep or vertical orientation. Overturned folds often occur in highly compressed geological settings, where intense tectonic forces cause significant deformation of the Earth's crust. These folds can be important indicators of the geological history and stress conditions in a region.


What is four fold symmetry?

It means 4 lines of symmetry as for example a square has 4 lines of symmetry


What is sides of a fold where curvature is at a minimum are termed?

The sides of a fold where curvature is at a minimum are termed "limbs." In geological terms, the limbs are the sections of the fold that extend away from the hinge, which is the point of maximum curvature. The angle between the limbs can vary, influencing the overall shape and classification of the fold.


How many lines of symitry does a circle have?

It has two lines of symitry. Symitry is when you can fold something in half and you get the same shape in both sides. For exaple: in a circle you have the same shape if you fold it horizontally or vertically. :)
