it decreases... that's why the two poles are the coldest places on earth... however, considering the earth is a sphere the angle you are talking about is relative to the point on earth which you are referring to... therefore, there will always be a point on the earth's surface where the suns rays are hitting at exactly 90 degrees...
If the sun's rays hit the Earth's surface at a direct spot, which is usually around the equator, that area would be the warmest. Any area that is far away from the sun's rays is usually cold.

The angle at which the sunlight strikes the Earth
Sunbeams do NOT strike the Earth's surface at the same angle. Like dusk some places have an angular strike during the winter months. This is the main reason we have seasons.

Because Earth is a sphere that is tilted on it's axis.

When it decreases the showdows get smaller and fade but when the angle increases the shadow gets bigger.
Swallows use both the Earth's magnetism and the angle of the sun to find their way to the tropics when they migrate. They may also use topographic features and their sense of smell to find their way to the tropics for the winter.
